&lt;p&gt;Named the MACDefender, the scareware sample shows a bogus interface,  insisting that the end user is infected, and that their OS is in an  insecure state. The researchers emphasize on the social engineering  elements of the scareware, including the fact that although the site  shows a fake Windows screen, the scareware itself is a well designed Mac  application with no spelling or grammar mistakes in its description.&lt;/p&gt; &lt;p&gt;The scareware will periodically open pornographic content on the  affected Mac, in order to trick the users into thinking they’re infected  with malware. The scareware is sold for $59,95, part of a scareware  affiliate network targeting Mac OS X users in particular.&lt;/p&gt; &lt;p&gt;Users are advised to exercise extra caution when dealing with  suspicious downloads, especially ones delivered through blackhat search  engine optimization techniques.&lt;/p&gt;&lt;p&gt;[Source:&lt;a href="http://www.zdnet.com/blog/security/new-mac-os-x-scareware-delivered-through-blackhat-seo/8614"&gt; zdnet&lt;/a&gt;]&lt;br /&gt;&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-6757978510646581453?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/6757978510646581453/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=6757978510646581453' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/6757978510646581453'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/6757978510646581453'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2011/05/new-mac-os-x-scareware-delivered.html' title='New MAC OS X scareware delivered through blackhat SEO'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-4831100150002123677</id><published>2011-04-18T07:27:00.001-07:00</published><updated>2011-04-18T07:33:15.776-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Windows'/><category scheme='http://www.blogger.com/atom/ns#' term='Adobe'/><category scheme='http://www.blogger.com/atom/ns#' term='Metasploit'/><category scheme='http://www.blogger.com/atom/ns#' term='Exploit'/><title type='text'>Emergency Adobe Flash Player patch coming today</title><content type='html'>&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=8548"&gt;&lt;img class="size-full wp-image-2344 alignright" title="Adobe Flash, Apple Safari fail privacy tests" src="http://i.zdnet.com/blogs/2009/01/broken_flash.png" alt="" width="128" height="128" /&gt;&lt;/a&gt;&lt;/p&gt; &lt;p&gt;&lt;br /&gt;&lt;/p&gt;&lt;p&gt;Less than a week after warning that hackers were embedding malicious  Flash Player files (.swf) into Microsoft Word documents to launch  targeted malware attacks, Adobe plans to release an emergency Flash  Player patch today to fix the underlying problem.&lt;/p&gt; &lt;p&gt;The patch will fix a “critical” vulnerability in Flash Player  10.2.153.1 and earlier versions for Windows, Mac OS X Linux and Solaris.&lt;/p&gt; &lt;p&gt;&lt;span id="more-8548"&gt;&lt;/span&gt;&lt;/p&gt; &lt;p&gt;According to this &lt;a href="http://secunia.com/advisories/44119/"&gt;Secunia advisory&lt;/a&gt;, the flaw allows a hacker to completely hijack a vulnerable Windows computer:&lt;/p&gt; &lt;p style="padding-left: 30px;"&gt;&lt;em&gt;A vulnerability has been reported in  Adobe Flash Player, which can be exploited by malicious people to  compromise a user’s system.&lt;/em&gt;&lt;/p&gt; &lt;p style="padding-left: 30px;"&gt;&lt;em&gt;The vulnerability is caused due to an  error when parsing ActionScript that adds a custom function to the  prototype of a predefined class. This results in incorrect  interpretation of an object (i.e. object type confusion) when calling  the custom function, which causes an invalid pointer to be dereferenced.&lt;/em&gt;&lt;/p&gt; &lt;p&gt;Secunia has posted a &lt;a href="http://secunia.com/blog/210"&gt;technical analysis&lt;/a&gt; of the flaw as well.&lt;/p&gt; &lt;p&gt;Adobe has confirmed that the vulnerability (CVE-2011-0611) could  cause a crash and potentially allow an attacker to take control of the  affected system.&lt;/p&gt; &lt;p style="padding-left: 30px;"&gt;&lt;em&gt;There are reports that this  vulnerability is being exploited in the wild in targeted attacks via a  malicious Web page or a Flash (.swf) file embedded in a Microsoft Word  (.doc) or Microsoft Excel (.xls) file delivered as an email attachment,  targeting the Windows platform. At this time, Adobe is not aware of any  attacks via PDF targeting Adobe Reader and Acrobat. Adobe Reader X  Protected Mode mitigations would prevent an exploit of this kind from  executing.&lt;/em&gt;&lt;/p&gt; &lt;p&gt;A patch for Google Chrome users is already available in &lt;a href="http://googlechromereleases.blogspot.com/2011/03/stable-and-beta-channel-updates_15.html"&gt;Chrome version 10.0.648.205&lt;/a&gt;.&lt;/p&gt;

Details from Adobe’s &lt;a href="http://www.adobe.com/support/security/bulletins/apsb09-08.html"&gt;advisory&lt;/a&gt;:&lt;/p&gt; &lt;p&gt;&lt;span id="more-3664"&gt;&lt;/span&gt;&lt;/p&gt; &lt;p style="padding-left: 30px;"&gt;This vulnerability could allow an attacker who successfully exploits this vulnerability to take control of the affected system.  Adobe has provided a solution for the reported vulnerability (CVE-2009-1860).  This issue was previously resolved in Shockwave Player 11.0.0.465; the Shockwave Player 11.5.0.600 update resolves a backwards compatibility mode variation of the issue with Shockwave Player 10 content.  To resolve this issue, Shockwave Player users on Windows should uninstall Shockwave version 11.5.0.596 and earlier on their systems, restart, and install Shockwave version 11.5.0.600, available here: &lt;a href="http://get.adobe.com/shockwave/"&gt;http://get.adobe.com/shockwave/&lt;/a&gt;.

These vulnerabilities affect all versions of Windows, including Vista and Windows Server 2008.  Microsoft expects to see exploit code for these flaws but reckons the reliability will be “inconsistent.”&lt;/li&gt;&lt;li&gt;&lt;a href="http://www.microsoft.com/technet/security/Bulletin/MS09-007.mspx" target="_blank"&gt;MS09-007&lt;/a&gt;: (IMPORTANT): This bulletin includes a patch for &lt;em&gt;a solitary vulnerability&lt;/em&gt; in Windows, which could allow spoofing if an attacker gains access to the certificate used by the end user for authentication.  Again, Microsoft says “inconsistent exploit code” is likely.   The bulletin is available for all versions of Windows — Windows 2000 through Windows Server 2008.&lt;/li&gt;&lt;li&gt;&lt;a href="http://www.microsoft.com/technet/security/Bulletin/MS09-008.mspx" target="_blank"&gt;MS09-008&lt;/a&gt; (IMPORTANT): This update resolves&lt;em&gt; two privately reporte&lt;/em&gt;d vulnerabilities and &lt;em&gt;two publicly disclosed&lt;/em&gt; vulnerabilities in Windows , which could allow a remote attacker to redirect network traffic intended for systems on the Internet to the attacker’s own systems. Microsoft says the patches correct the way that Windows DNS servers cache and validate queries, and by modifying the way that Windows DNS servers and Windows WINS servers handle WPAD and ISATAP registration.  For these issues, Microsoft warns that “consistent exploit code” is likely.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;Windows users should treat the “critical” bulletin with the highest possible priority.&lt;/p&gt;&lt;p&gt;[Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;] &lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-7489023278574931374?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/7489023278574931374/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=7489023278574931374' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/7489023278574931374'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/7489023278574931374'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/03/microsoft-fixes-critical-windows-kernel.html' title='Microsoft fixes critical Windows kernel, WINS flaws'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-4842214383477830750</id><published>2009-03-12T23:03:00.000-07:00</published><updated>2009-03-12T23:09:17.009-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Passwords'/><category scheme='http://www.blogger.com/atom/ns#' term='Spam And Phishing'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Hackers'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Botnets'/><category scheme='http://www.blogger.com/atom/ns#' term='Phlashing Attacks'/><title type='text'>New study details the dynamics of successful phishing</title><content type='html'>&lt;a href="http://blogs.zdnet.com/security/?p=2846#comments"&gt;&lt;span&gt;&lt;/span&gt;&lt;/a&gt;&lt;a href="http://i.zdnet.com/blogs/phishme_ethical_phishing_demo.jpg"&gt;&lt;img class="size-full wp-image-2847 alignleft" src="http://i.zdnet.com/blogs/phishme_ethical_phishing_demo.jpg" alt="" height="110" width="150" /&gt;&lt;/a&gt;Can you teach an old employee new phishing protection tricks? &lt;p&gt;In a recently presented &lt;a href="http://www.misti.com/includes/conferences/agendadetails.asp?pID=174&amp;amp;ISS=21541&amp;amp;SID=697529"&gt;study by the Intrepidus Group&lt;/a&gt;, the company behind the &lt;a href="http://phishme.com/"&gt;PhishMe.com&lt;/a&gt; spear phishing awareness service allowing companies to ethically attempt to phish their employees on their way to build security awareness, &lt;a href="http://media.haymarketmedia.com/Documents/2/InfoSecWorld-2009_1415.pdf"&gt;presents some interesting key findings&lt;/a&gt; based on 32 phishing scenarios tested against a total of 69,000 employees around the world. Here they are:&lt;/p&gt; &lt;p&gt;&lt;span id="more-2846"&gt;&lt;/span&gt;&lt;/p&gt; &lt;ul&gt;&lt;li&gt;23% of people worldwide are vulnerable to targeted/spear phishing attacks&lt;/li&gt;&lt;li&gt;Phishing attacks that use an authoritative tone are 40% more successful than those that attempt to lure people through reward-giving&lt;/li&gt;&lt;li&gt;Men and women are both equally susceptible to phishing&lt;/li&gt;&lt;li&gt;On an average 60% of corporate employees that were found susceptible to targeted spear phishing responded to the phishing emails within three hours of receiving them&lt;/li&gt;&lt;li&gt;People are less cautious when clicking on active links in emails than when they are requested for sensitive data&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;Metrics are invaluable, but in this case the obsession with metrics can result in more insecurities since it excludes the possibility of blended threats. For instance, last year I was closely monitoring a similar &lt;a href="http://ddanchev.blogspot.com/2008/05/skype-phishing-pages-serving-exploits.html"&gt;blended Skype phishing campaign&lt;/a&gt;, where the cybercriminals (IkbMan) were attempting to optimize the click-through rate of their campaign by &lt;a href="http://ddanchev.blogspot.com/2008/12/skype-phishing-pages-serving-exploits.html"&gt;serving client-side exploits to the visitors&lt;/a&gt;, “just in case” if they find the site suspicious and do not enter any accounting data. For the time being the exploit is served instantly upon visiting the phishing site, however, the possibility for serving it only if the user hasn’t entered anything and is leaving the site is always there.&lt;/p&gt; &lt;ul&gt;&lt;li&gt;Go through related phishing trends and tactics: &lt;a href="http://blogs.zdnet.com/security/?p=2707"&gt;Research: 76% of phishing sites hosted on compromised servers&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=2366"&gt;Microsoft study debunks phishing profitability&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=1641"&gt;Phishers increasingly scamming other phishers&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=1104"&gt;DIY phishing kits introducing new features&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=2095"&gt;Phishers apply quality assurance, start validating credit card numbers&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=2064"&gt;Lack of phishing attacks data sharing puts $300M at stake annually&lt;/a&gt;&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;Considering one of the key points from Intrepidus Group’s study, namely that “&lt;em&gt;People are less cautious when clicking on active links in emails than when they are requested for sensitive data&lt;/em&gt;“, a phishing email should be treated as spam, namely (in a perfect world) it shouldn’t be even allowed to reach the employee’s mailbox. Otherwise, it appears that the trade-off for coming up with quality metrics on the current degree of security awareness in regard to phishing, is the potential exposure of the tested population against potential blended threats.&lt;/p&gt; &lt;p&gt;With managed localization services in the sense of dedicated translators of messages to be used in spam, phishing, and malware campaigns already a fact, the cybercrime ecosystem will soon be talking in a native language, and with the increasingly automated phishing tools whose features were once available to a more sophisticated crowd of cybecriminals, now available for free - the future of phishing looks promising.&lt;/p&gt; &lt;p&gt;The only threat that can outpace its growth &lt;a href="http://blogs.zdnet.com/security/?p=2275"&gt;is the threat posed by&lt;/a&gt; the much more efficient and sophisticated &lt;a href="http://blogs.zdnet.com/security/?p=2596"&gt;financial data targeting tactic of using crimeware&lt;/a&gt; targeting each and every E-banking site simultaneously upon successful infection.&lt;/p&gt;&lt;p&gt;[Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;] &lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-4842214383477830750?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/4842214383477830750/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=4842214383477830750' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/4842214383477830750'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/4842214383477830750'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/03/new-study-details-dynamics-of.html' title='New study details the dynamics of successful phishing'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-6375159192470877262</id><published>2009-03-12T23:00:00.000-07:00</published><updated>2009-03-12T23:03:54.761-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Passwords'/><category scheme='http://www.blogger.com/atom/ns#' term='XSS Exploit'/><category scheme='http://www.blogger.com/atom/ns#' term='SQL Injection'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Anti Virus'/><category scheme='http://www.blogger.com/atom/ns#' term='Hackers'/><category scheme='http://www.blogger.com/atom/ns#' term='Pen testing'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Phlashing Attacks'/><title type='text'>International Kaspersky sites susceptible to SQL injection attacks</title><content type='html'>&lt;p&gt;&lt;a href="http://i.zdnet.com/blogs/kaspersky_iframe_injected.gif"&gt;&lt;img class="size-full wp-image-2843 alignleft" src="http://i.zdnet.com/blogs/kaspersky_iframe_injected.gif" alt="" height="96" width="142" /&gt;&lt;/a&gt;According to a security group going under the name of &lt;a href="http://nemesis.te-home.net/index.html?about"&gt;TeamElite&lt;/a&gt;, the international sites of Kaspersky Iran (&lt;strong&gt;kasperskylabs.ir&lt;/strong&gt;), Taiwan (&lt;strong&gt;web.kaspersky.com.tw&lt;/strong&gt;) and South Korea (&lt;strong&gt;kasperskymall.co.kr)&lt;/strong&gt;

&lt;p&gt;&lt;span id="more-2842"&gt;&lt;/span&gt;&lt;/p&gt; &lt;p&gt;The group’s analysis comes shortly after the series of posts by a Romanian group of serial pen-testers of security vendors, which discovered similar flaws in the web sites of &lt;a href="http://www.hackersblog.org/2009/02/11/f-securecom-sql-injection-cross-site-scripting/"&gt;F-Secure&lt;/a&gt;, &lt;a href="http://www.hackersblog.org/2009/02/18/emeasymanteccom-vulnerabil-la-blind-sql-injection/"&gt;Symantec&lt;/a&gt;, &lt;a href="http://www.hackersblog.org/2009/02/15/in-atentia-bitdefender/"&gt;BitDiffender&lt;/a&gt;, and &lt;a href="http://www.hackersblog.org/2009/02/07/usakasperskycom-hacked-full-database-acces-sql-injection/"&gt;Kaspersky USA&lt;/a&gt;.&lt;/p&gt; &lt;p&gt;Let’s start from the basics. PR contingency planning in the spirit of total denial is perhaps the worst thing a vendor can do in this case. Despite the fact that these are reseller web sites and are managed by local companies, they still have the license to harness the power of the brand of an information security company, and therefore not demonstrating basic security awareness by taking care of trivial web application vulnerabilities on these sites, can undermine the brand’s integrity and what it stands for at the first place.&lt;/p&gt; &lt;p&gt;From a pragmatic perspective, the licensing company can either exercise pen-testing authority over the locally managed web sites, keep an eye on them through &lt;a href="http://xssed.com/earlywarning"&gt;community service warning systems&lt;/a&gt;, or introduce obligatory pen-testing before a license is obtained.&lt;/p&gt; &lt;p&gt;Both groups have been notifying the affected vendors according to their posts.&lt;/p&gt;&lt;p&gt;[Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;] &lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-6375159192470877262?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/6375159192470877262/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=6375159192470877262' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/6375159192470877262'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/6375159192470877262'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/03/international-kaspersky-sites.html' title='International Kaspersky sites susceptible to SQL injection attacks'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-418999319098887408</id><published>2009-03-12T22:56:00.000-07:00</published><updated>2009-03-12T23:00:43.799-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Passwords'/><category scheme='http://www.blogger.com/atom/ns#' term='Exploit Code'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Anti Virus'/><category scheme='http://www.blogger.com/atom/ns#' term='Adobe'/><category scheme='http://www.blogger.com/atom/ns#' term='Arbitrary  Code  Execution'/><category scheme='http://www.blogger.com/atom/ns#' term='Hackers'/><category scheme='http://www.blogger.com/atom/ns#' term='Pen testing'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Botnets'/><title type='text'>USAID.gov compromised, malware and exploits served</title><content type='html'>&lt;a href="http://blogs.zdnet.com/security/?p=2817#comments"&gt;&lt;span&gt;0&lt;/span&gt;&lt;/a&gt;&lt;a href="http://i.zdnet.com/blogs/usaid.jpg"&gt;&lt;img class="size-full wp-image-2818 alignleft" src="http://i.zdnet.com/blogs/usaid.jpg" alt="" height="62" width="199" /&gt;&lt;/a&gt;The Azerbaijan section at the United States Agency for International Development (&lt;a href="http://www.google.com/safebrowsing/diagnostic?site=http://azerbaijan.usaid.gov/&amp;amp;hl=en"&gt;azerbaijan.usaid.gov&lt;/a&gt;) has been compromised and is embedded with malware and exploits serving scripts approximately around the 1st of March. The malicious script is taking advantage of a series of redirects which are dynamically loading live exploits, or rogue security software and are all currently active. &lt;a href="http://thompson.blog.avg.com/2009/03/usaid-indeed.html"&gt;Roger Thompson&lt;/a&gt; at AVG Technologies &lt;a href="http://www.youtube.com/watch?v=gjYhxsDeShQ&amp;amp;feature=channel_page"&gt;featured a video demonstrating&lt;/a&gt; what happens when an unprotected user visits the site. &lt;p&gt;Let’s dissect the attack, take into consideration the big picture, and bring a skeleton out of the closet — one of the malware’s phone back locations is a domain exclusively used by &lt;a href="http://en.wikipedia.org/wiki/Russian_Business_Network"&gt;the Russian Business Network&lt;/a&gt; back in January, 2008.&lt;/p&gt; &lt;p&gt;&lt;span id="more-2817"&gt;&lt;/span&gt;&lt;/p&gt; &lt;p&gt;&lt;a href="http://i.zdnet.com/blogs/usaid_compromised1.png"&gt;&lt;img class="size-full wp-image-2821 alignleft" src="http://i.zdnet.com/blogs/usaid_compromised1.png" alt="" height="43" width="220" /&gt;&lt;/a&gt;&lt;/p&gt; &lt;p&gt;This particular campaign relies on an embedded malicious script that appears to be dynamically creating subdomains within the cybercriminal’s controlled domain. For instance, &lt;strong&gt;cs.ucsb.edu.4afad2ceace1e653.should-be .cn/jan10 .cn&lt;/strong&gt; is where the first redirection in USAID.gov’s attack takes place. From there, the surfer is taken to &lt;strong&gt;orderasia .cn/index.php&lt;/strong&gt; and then to &lt;strong&gt;orderasia .cn/iepdf.php?f=old&lt;/strong&gt; where the exploitation of multiple (patched) Adobe Reader and Acrobat buffer overflows takes place.

A single instance of WarVOX on a residential broadband connection, with a typical VoIP account, can scan over 1,000 numbers per hour. The speed of WarVOX is limited only by downstream bandwidth and the limitations of the VoIP service. Using two providers with over 40 concurrent lines we have been able to scan entire 10,000 number prefixes within 3 hours.&lt;/em&gt;&lt;/li&gt;&lt;/ul&gt; &lt;ul&gt;&lt;li&gt;&lt;em&gt;The resulting call audio can be used to extract a list of modems that can be fed into a standard modem-based wardialing application for fingerprinting and banner collection. One of the great things about the WarVOX model is that once the data has been gathered, it is archived and available for re-analysis as new signatures, plugins, and tools are developed. The current release of WarVOX (1.0.0) is able to automatically detect modems, faxes, silence, voice mail boxes, dial tones, and voices.&lt;/em&gt;&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;Moore hopes WarVOX can replace the “slow and inefficient” systems currently in place to identify security holes in phone systems.&lt;/p&gt; &lt;p&gt;This &lt;a href="http://warvox.org/media/warvox-1.0.0.pdf"&gt;presentation&lt;/a&gt; (.pdf) covers the motivation behind the tools and the implementation details.&lt;/p&gt;[Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;]&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-7328979388088461000?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/7328979388088461000/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=7328979388088461000' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/7328979388088461000'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/7328979388088461000'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/03/metasploits-hd-moore-releases-war.html' title='Metasploit&apos;s HD Moore releases &apos;war dialing&apos; tools'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-2291857158021911354</id><published>2009-03-12T22:50:00.000-07:00</published><updated>2009-03-12T22:53:00.742-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Wi-Fi security'/><category scheme='http://www.blogger.com/atom/ns#' term='Patch Watch'/><category scheme='http://www.blogger.com/atom/ns#' term='Exploit Code'/><category scheme='http://www.blogger.com/atom/ns#' term='DDos Attack'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Data  theft'/><category scheme='http://www.blogger.com/atom/ns#' term='Arbitrary  Code  Execution'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Apple'/><title type='text'>Security holes in Apple Time Capsule, AirPort Base Station</title><content type='html'>&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=2799"&gt;&lt;img class="size-full wp-image-2800 alignleft" src="http://i.zdnet.com/blogs/apple_base_station.png" alt="" height="84" width="159" /&gt;&lt;/a&gt;Apple has released a firmware update with fixes for three documented security vulnerabilities affecting its Time Capsule and AirPort Base Station products.&lt;/p&gt; &lt;p&gt;The vulnerabilities could lead to denial-of-service or information disclosure attacks via specially crafted packets. Details on &lt;a href="http://support.apple.com/kb/HT3467"&gt;the vulnerabilities&lt;/a&gt;:&lt;/p&gt; &lt;p&gt;&lt;span id="more-2799"&gt;&lt;/span&gt;&lt;/p&gt; &lt;ul&gt;&lt;li&gt;&lt;strong&gt;CVE-2008-2476 - &lt;/strong&gt;The IPv6 Neighbor Discovery Protocol implementation does not validate the origin of Neighbor Discovery messages. By sending a maliciously crafted message, a remote user may cause a denial of service, observe private network traffic, or inject forged packets. This update addresses the issue by performing additional validation of Neighbor Discovery messages.&lt;/li&gt;&lt;li&gt;&lt;strong&gt;CVE-2008-0473&lt;/strong&gt; -  An out-of-bounds memory access issue exists in the handling of PPPoE discovery packets. By sending a maliciously crafted PPPoE discovery packet, a remote user may be able to cause an&lt;br /&gt;unexpected device shutdown. This update addresses the issue through improved bounds checking.&lt;/li&gt;&lt;li&gt;&lt;strong&gt;CVE-2008-3530&lt;/strong&gt; - When IPv6 support is enabled, IPv6 nodes use ICMPv6 to report errors encountered while processing packets. An implementation issue in the handling of incoming ICMPv6 “Packet Too Big” messages&lt;br /&gt;may cause an unexpected device shutdown. This update addresses the issue through improved handling of ICMPv6 messages.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;Apple says the update (firmware version 7.4.1)  is installed into Time Capsule or AirPort Base Station with 802.11n* via AirPort Utility provided with the device.&lt;/p&gt;&lt;p&gt;[Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;] &lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-2291857158021911354?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/2291857158021911354/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=2291857158021911354' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/2291857158021911354'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/2291857158021911354'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/03/security-holes-in-apple-time-capsule.html' title='Security holes in Apple Time Capsule, AirPort Base Station'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-8868463509669681093</id><published>2009-03-12T22:38:00.000-07:00</published><updated>2009-03-12T22:46:57.671-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Zero-Day  Attacks'/><category scheme='http://www.blogger.com/atom/ns#' term='Spam And Phishing'/><category scheme='http://www.blogger.com/atom/ns#' term='Patch Watch'/><category scheme='http://www.blogger.com/atom/ns#' term='Complex Attacks'/><category scheme='http://www.blogger.com/atom/ns#' term='Viruses And Worms'/><category scheme='http://www.blogger.com/atom/ns#' term='Arbitrary  Code  Execution'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><title type='text'>Coming on Patch Tuesday: 3 Windows bulletins, 1 critical</title><content type='html'>&lt;a href="http://blogs.zdnet.com/security/?p=2794#comments"&gt; &lt;span&gt;&lt;/span&gt;&lt;/a&gt;&lt;a href="http://blogs.zdnet.com/security/?p=2794"&gt;&lt;img class="size-full wp-image-2796 alignleft" src="http://i.zdnet.com/blogs/windows_update_icon.png" alt="" height="91" width="91" /&gt;&lt;/a&gt;Microsoft today outlined plans to ship three security bulletins for software vulnerabilities in the Windows operating system. &lt;p&gt;One of the three bulletins will carry a “critical” rating, meaning that it will cover flaws that could be exploited to launch remote code execution attacks.&lt;/p&gt; &lt;p&gt;&lt;span id="more-2794"&gt;&lt;/span&gt;&lt;/p&gt; &lt;p&gt;According to the &lt;a href="http://www.microsoft.com/technet/security/bulletin/ms09-mar.mspx"&gt;advance notice&lt;/a&gt; from Microsoft, the other two bulletins are rated “important” and can expose Windows users to spoofing attacks.&lt;/p&gt; &lt;p&gt;All three bulletins require a restart after deployment.&lt;/p&gt; &lt;p&gt;All supported versions of Windows will be affected by next Tuesday’s releases, including the newer Windows Vista and Windows Server 2008.&lt;/p&gt; &lt;p&gt;This month’s batch of patches will NOT include a fix for a known — and under attack — code execution vulnerability affecting Microsoft Office.

The CSRF flaw affects Gmail’s “Change Password” function, since according to Diaz the session cookie is automatically sent by the browser in every request making the attack possible.&lt;/p&gt; &lt;p&gt;Google’s response came fast, and it’s in the form of - “&lt;a href="http://www.darkreading.com/security/vulnerabilities/showArticle.jhtml?articleID=215800241"&gt;We do not consider this case to be a significant vulnerability.&lt;/a&gt;” :&lt;/p&gt; &lt;p&gt;&lt;span id="more-2773"&gt;&lt;/span&gt;&lt;/p&gt; &lt;blockquote&gt;&lt;p&gt;We’ve been aware of this report for some time, and we do not consider this case to be a significant vulnerability, since a successful exploit would require correctly guessing a user’s password within the period that the user is visiting a potential attacker’s site,” the spokesperson said. “Despite  the very low chance of guessing a password in this way, we will explore ways to further mitigate the issue. We always encourage users to choose strong passwords, and we have an indicator to help them do this.&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;Compared to the futile password guessing attempts in order to execute the attack, nothing can replace flaw-independent approaches like social engineering. From a pragmatic perspective, malicious attackers have an extensive number of tactics to chose from if they were trying to obtain your Gmail password. Starting from plain simple &lt;a href="http://blogs.zdnet.com/security/?p=2682"&gt;phishing campaigns&lt;/a&gt;, and going to a more &lt;a href="http://www.garchiver.com/what-happened.htm"&gt;efficiency-centered&lt;/a&gt; approaches - remember the &lt;a href="http://www.codinghorror.com/blog/archives/001072.html"&gt;G-Archiver&lt;/a&gt; fiasco?&lt;/p&gt; &lt;ul&gt;&lt;li&gt;Related posts: &lt;a href="http://blogs.zdnet.com/security/?p=1911"&gt;Google downplays Chrome’s carpet-bombing flaw&lt;/a&gt;;

was the &lt;a href="http://mtc.sri.com/Conficker/"&gt;pseudo-random domain generation algorithm&lt;/a&gt; used for the generation of dynamic command and control locations in order to make it nearly impossible for researchers and the industry to take them down.  However, once the domain registration algorithm was successfully reverse engineering, it became possible to &lt;a href="http://blogs.zdnet.com/security/?p=2388"&gt;measure the estimated number of affected hosts&lt;/a&gt; by registering several of the upcoming phone back locations.&lt;/p&gt; &lt;p&gt;What if the Conficker worm suddenly decided that the phone-back locations for March were those of legitimate sites?&lt;/p&gt; &lt;p&gt;&lt;span id="more-2754"&gt;&lt;/span&gt;&lt;/p&gt; &lt;p&gt;&lt;a href="http://www.sophos.com/security/blog/2009/03/3457.html"&gt;According to Sophos&lt;/a&gt;, during March, the millions of Conficker infected hosts will attempt to phone back to several legitimate domains, among which is a Southwest Airlines owned &lt;strong&gt;wnsux.com&lt;/strong&gt;, potentially causing a distributed denial of service attack on all of them. Here’s a list of the legitimate domains and dates on which Conficker will attempt to contact/potentially DDoS them:&lt;/p&gt; &lt;p&gt;Music Search Engine - &lt;strong&gt;jogli.com&lt;/strong&gt; on 8th of March&lt;br /&gt;Southwest Airlines - &lt;strong&gt;wnsux.com&lt;/strong&gt; on 13th of March&lt;br /&gt;Women’s Net in Qinghai Province - &lt;strong&gt;qhflh.com&lt;/strong&gt; on 18th of March&lt;br /&gt;Phonetics by Computer - &lt;strong&gt;praat.org&lt;/strong&gt; on 31th of March&lt;/p&gt; &lt;p&gt;In an attempt to mitigate this attack, Southwest Airlines owned &lt;strong&gt;wnsux.com&lt;/strong&gt; domains was modified yesterday and is no longer resolving to a particular IP. However, &lt;strong&gt;praat.org&lt;/strong&gt; is a redirect to the &lt;a href="http://www.fon.hum.uva.nl/praat/"&gt;University of Amsterdam’s Institute of Phonetic Sciences&lt;/a&gt; and just like &lt;strong&gt;qhflh.com &lt;/strong&gt;and &lt;strong&gt;jogli.com &lt;/strong&gt;is still active.&lt;/p&gt; &lt;p&gt;The reverse engineering of the domain registration algorithm not only made it possible to anticipate the upcoming command and control locations, but also, allowed security companies to pre-register them and lock them under the &lt;a href="http://asert.arbornetworks.com/2009/02/the-conficker-cabal-announced/"&gt;Conficker Cabal alliance with members such as Microsoft and the ICANN&lt;/a&gt;.  Moreover, perhaps the most pragmatic mitigation solution implemented on a large scale so far, has been &lt;a href="http://blog.opendns.com/2009/02/09/stats-are-back-and-conficker/"&gt;OpenDNS updated Stats System which automatically stops resolving Conficker’s latest domains&lt;/a&gt;, a feature which they introduced last month.&lt;/p&gt; &lt;p&gt;For the time being, the Conficker botnet remains in a “stay tuned” mode with the real malicious payload to be delivered at any particular moment. &lt;a href="http://www.microsoft.com/technet/security/Bulletin/MS08-067.mspx"&gt;A patch has been available&lt;/a&gt; since October, 2008.&lt;/p&gt; &lt;p&gt;&lt;em&gt;Conficker graph courtesy of &lt;a href="http://blogs.technet.com/mmpc"&gt;Microsoft’s Malware Protection Center&lt;/a&gt;.&lt;/em&gt;&lt;/p&gt;&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;] &lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-551118992696309652?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/551118992696309652/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=551118992696309652' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/551118992696309652'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/551118992696309652'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/03/conficker-worm-to-ddos-legitimate-sites.html' title='Conficker worm to DDoS legitimate sites in March'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-3048098350997392803</id><published>2009-03-09T05:33:00.000-07:00</published><updated>2009-03-09T05:41:00.935-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Mozilla'/><category scheme='http://www.blogger.com/atom/ns#' term='Exploit Code'/><category scheme='http://www.blogger.com/atom/ns#' term='iPhone'/><category scheme='http://www.blogger.com/atom/ns#' term='Reverse Engineering'/><category scheme='http://www.blogger.com/atom/ns#' term='Adobe'/><category scheme='http://www.blogger.com/atom/ns#' term='Hackers'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Apple'/><category scheme='http://www.blogger.com/atom/ns#' term='Vulnerability Research'/><category scheme='http://www.blogger.com/atom/ns#' term='Patch Watch'/><category scheme='http://www.blogger.com/atom/ns#' term='DDos Attack'/><category scheme='http://www.blogger.com/atom/ns#' term='Data  theft'/><category scheme='http://www.blogger.com/atom/ns#' term='Arbitrary  Code  Execution'/><title type='text'>Pwn2Own hacker: Apple Safari is 'easy pickings'</title><content type='html'>&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=2748"&gt;&lt;img class="alignleft" src="http://blogs.zdnet.com/security/images/apple_safari.jpg" alt="" height="76" width="76" /&gt;&lt;/a&gt;Charlie Miller, the security researcher who won last year’s Pwn2Own hacker contest, is predicting that Apple’s Safari browser will be the easiest target this year.&lt;/p&gt; &lt;p&gt;In a note posted on the popular Daily Dave mailing list, Miller describes Safari as “easy pickin’s” and forecasts that at least four zero-day Safari flaws will be used during &lt;a href="http://blogs.zdnet.com/security/?p=2531"&gt;the contest at CanSecWest&lt;/a&gt; later this month.&lt;/p&gt; &lt;p&gt;&lt;span id="more-2748"&gt;&lt;/span&gt;&lt;strong&gt;[ SEE: &lt;a title="Permanent Link to Pwn2Own hacker contest targets browsers, smart phones" rel="bookmark" href="http://blogs.zdnet.com/security/?p=2531"&gt;Pwn2Own hacker contest targets browsers, smart phones&lt;/a&gt; ]&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;This year’s contest will pit hackers &lt;a href="http://dvlabs.tippingpoint.com/blog/2009/02/25/pwn2own-2009"&gt;against browsers and smart phones&lt;/a&gt; with Internet Explorer, Firefox, Safari, Opera and Chrome among the high-profile targets.

(If you’re unfamiliar with these attacks, I recommend reading about them at the &lt;/em&gt;&lt;a href="http://owasp.org/" target="_blank"&gt;&lt;em&gt;Open Web Application Security Project (OWASP) Web&lt;/em&gt;&lt;/a&gt;&lt;em&gt;.) We could mitigate much of the risk of these vulnerabilities by frequently changing our URLs — not once every 200 years but once every 10 minutes. Attackers would no longer be able to exploit application vulnerabilities by mass e-mailing poisoned hyperlinks because the links would be broken and invalid by the time the messages reached their intended victims.&lt;/em&gt;&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;Of course, there are some caveats, especially in cases where bookmarking and e-mailing static links are necessary:&lt;/p&gt; &lt;ul&gt;&lt;li&gt;&lt;em&gt;URL rewriting may not be appropriate for all applications. One negative side effect of this approach is that although attackers are no longer able to e-mail malicious hyperlinks, legitimate users are similarly prevented from sending valid links or even from bookmarking pages in the application. Any page marked as a landing page could be bookmarked, but as I mentioned before, you need to be very cautious when using landing pages. Therefore, if you expect users of your application to bookmark pages other than the home page, URL rewriting is probably not a good solution for you.&lt;/em&gt;&lt;/li&gt;&lt;li&gt;&lt;em&gt;Additionally, while URL rewriting is a fast and easy defense-in-depth mechanism, it is just that: defense-in-depth. It is by no means a silver bullet against XSS or any other attacks. An automatically expiring URL can still be exploited by an attacker with access to a Web server of his own. Instead of sending out malicious hyperlinks that point directly to the vulnerable page, he can send out hyperlinks that point to his own site. When his site gets a hit from one of the phished e-mails, it can contact a landing page on the vulnerable site to obtain a valid time stamp and then redirect the user accordingly.&lt;/em&gt;&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;Sullivan argues that URL rewriting does make the attacker’s work more difficult: he now has to convince a user to follow a hyperlink to his Web site (evil.contoso.com) rather than a trusted one (&lt;a title="www.msn.com" href="http://www.msn.com/" target="_blank"&gt;www.msn.com&lt;/a&gt;), and he is also leaving a very clear trail back to himself for law enforcement agencies to follow. However, this will probably be of little comfort to any victims who fall for the phished e-mail and have their identities stolen as a result.&lt;/p&gt; &lt;ul&gt;&lt;li&gt;&lt;em&gt;Do use URL rewriting as an extra defensive measure, but always be sure to address vulnerabilities at the root of the problem.&lt;/em&gt;&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;Read the &lt;a href="http://msdn.microsoft.com/en-us/magazine/dd458793.aspx" target="_blank"&gt;entire article here&lt;/a&gt;.&lt;/p&gt;&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;] &lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-7704806451297657444?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/7704806451297657444/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=7704806451297657444' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/7704806451297657444'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/7704806451297657444'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/03/url-rewriting-can-help-thwart-web-app.html' title='URL rewriting can help thwart Web app attacks'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-1982857184180643136</id><published>2009-02-28T02:54:00.000-08:00</published><updated>2009-02-28T02:56:29.947-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Windows Vista'/><category scheme='http://www.blogger.com/atom/ns#' term='Vulnerability Research'/><category scheme='http://www.blogger.com/atom/ns#' term='Complex Attacks'/><category scheme='http://www.blogger.com/atom/ns#' term='Data  theft'/><category scheme='http://www.blogger.com/atom/ns#' term='Arbitrary  Code  Execution'/><category scheme='http://www.blogger.com/atom/ns#' term='Microsoft'/><title type='text'>Microsoft takes aim at Vista 'SoftMod' hack</title><content type='html'>&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=2720"&gt;&lt;img class="size-full wp-image-2724 alignleft" style="" src="http://i.zdnet.com/blogs/win_vista_logo.png" alt="" height="75" width="102" /&gt;&lt;/a&gt;Starting this week, Microsoft will ship an update to Windows Vista Ultimate users to ferret out cracked copies of its most expensive and feature-packed operating system.&lt;/p&gt; &lt;p&gt;The renewed anti-piracy campaign is aimed directly at the activation exploit known as the “SoftMod hack,” according to a post on Microsoft’s WGA blog.&lt;/p&gt; &lt;p&gt;&lt;span id="more-2720"&gt;&lt;/span&gt;&lt;/p&gt; &lt;p&gt;This &lt;a href="http://support.microsoft.com/kb/940510"&gt;Knowledge Base article explains&lt;/a&gt;:&lt;/p&gt; &lt;ul&gt;&lt;li&gt;This update enables Windows Vista to detect activation exploits that bypass product activation and that interfere with usual Windows operation. An activation exploit is a form of software that replaces or modifies authentic Windows components. When activation exploits are present on a system, it indicates that a software or hardware vendor may have tampered with genuine Windows to enable the sale of counterfeit software. Therefore, the security and the privacy of the computer are put at risk. After this update is installed, you will know if activation exploits are present on the system.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;According to Alex Kochis, director of Microsoft’s Windows Genuine group, &lt;a href="http://blogs.msdn.com/wga/archive/2009/02/24/update-to-windows-vista-activation-exploit-detection-begins-today.aspx"&gt;this is what a user would see&lt;/a&gt; on a  system that has detected the SoftMod activation exploit:&lt;/p&gt; &lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=2720"&gt;&lt;img class="alignnone size-full wp-image-2725" src="http://i.zdnet.com/blogs/softmod_hack.png" alt="" height="456" width="480" /&gt;&lt;/a&gt;&lt;/p&gt; &lt;p&gt;&lt;em&gt;* Hat tip: &lt;a href="http://www.computerworld.com/action/article.do?command=viewArticleBasic&amp;amp;articleId=9128592&amp;amp;source=rss_topic17"&gt;Gregg Keizer&lt;/a&gt;.&lt;/em&gt;&lt;/p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;]&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-1982857184180643136?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/1982857184180643136/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=1982857184180643136' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/1982857184180643136'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/1982857184180643136'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/02/microsoft-takes-aim-at-vista-softmod.html' title='Microsoft takes aim at Vista &apos;SoftMod&apos; hack'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-8672863215530684674</id><published>2009-02-28T02:51:00.000-08:00</published><updated>2009-02-28T02:53:33.384-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Vulnerability Research'/><category scheme='http://www.blogger.com/atom/ns#' term='Zero-Day  Attacks'/><category scheme='http://www.blogger.com/atom/ns#' term='Complex Attacks'/><category scheme='http://www.blogger.com/atom/ns#' term='Exploit Code'/><category scheme='http://www.blogger.com/atom/ns#' term='Open Source'/><category scheme='http://www.blogger.com/atom/ns#' term='Arbitrary  Code  Execution'/><category scheme='http://www.blogger.com/atom/ns#' term='Pen testing'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Web 2.0'/><title type='text'>Google wants to buy Native Client security flaws</title><content type='html'>&lt;a href="http://blogs.zdnet.com/security/?p=2702#comments"&gt;&lt;span&gt;&lt;/span&gt;&lt;/a&gt;&lt;a href="http://i.zdnet.com/blogs/google_code_small.png"&gt;&lt;img class="size-full wp-image-2703 alignleft" src="http://i.zdnet.com/blogs/google_code_small.png" alt="" height="55" width="153" /&gt;&lt;/a&gt;Google is (indirectly) buying security vulnerabilities from white hat hackers. &lt;p&gt;Under the guise of a Native Client Security Contest, the search engine firm is offering big cash prizes to hackers who find bugs and other security flaws in the open-source research technology for running x86 native code in Web applications.&lt;/p&gt; &lt;p&gt;&lt;span id="more-2702"&gt;&lt;/span&gt;&lt;/p&gt; &lt;p&gt;&lt;strong&gt;[ SEE: &lt;a title="Permanent Link to Android security team appeals to hackers" rel="bookmark" href="http://blogs.zdnet.com/security/?p=1746"&gt;Android security team appeals to hackers&lt;/a&gt; ]&lt;br /&gt;&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;From the contest &lt;a href="http://code.google.com/contests/nativeclient-security/faq.html" target="_blank"&gt;FAQ&lt;/a&gt;:&lt;/p&gt; &lt;ul&gt;&lt;li&gt;To participate, you will need to test the Native Client builds, identify security exploits which affect the current Native Client build at the time of submission and report them to our team.

Or the &lt;a href="http://blogs.zdnet.com/security/?p=2544"&gt;massive comment-spam attack on Digg.com&lt;/a&gt;?&lt;/p&gt; &lt;p&gt;It appears that the cybercriminals behind both of these campaigns aren’t giving up just yet, and are currently experimenting with a catchy social engineering attack at YouTube which is once again attempting to serve rogue security software under the disguise of a required media codec.&lt;/p&gt; &lt;p&gt;Here’s how the new campaign looks like.&lt;/p&gt; &lt;p&gt;&lt;span id="more-2695"&gt;&lt;/span&gt;&lt;/p&gt; &lt;p&gt;&lt;a href="http://i.zdnet.com/blogs/youtube_social_engineering_fake_codec.jpg"&gt;&lt;img class="size-full wp-image-2697 alignleft" src="http://i.zdnet.com/blogs/youtube_social_engineering_fake_codec.jpg" alt="" height="107" width="170" /&gt;&lt;/a&gt;This time their experiment relies on a new “visual social engineering vector”, a message “&lt;em&gt;Click Here to Join the Club&lt;/em&gt;” or “&lt;em&gt;Click Here for Free Porn&lt;/em&gt;” is embedded within the legitimate video, with a pointer enticing the user into clicking on the PornTube link right next to it. This novel approach slightly differs from previous campaigns involving fake YouTube sites, or the use of the very same malware links this time basically posted within the comments of a video.&lt;/p&gt; &lt;p&gt;The campaign does suffer from a major weakness, and that’s its adult content which YouTube has already — perhaps automatically — started removing. The fake codecs used in the campaign act as downloaders for rogue security software, with the cybercriminals earning revenue in the process. Moreover, not only are the Google Video, Digg.com’s and this latest campaign launched by the same attackers, but the malware campaigners behind them continue using highly toxic net blocks residing within the Latvian DATORU EXPRESS SERVISS Ltd (&lt;strong&gt;zlkon.lv&lt;/strong&gt;), and the Dutch WORLDSTREAM DBM  which makes them fairly easy to keep track of - at least for now.&lt;/p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;]&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-1343105959742523702?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/1343105959742523702/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=1343105959742523702' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/1343105959742523702'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/1343105959742523702'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/02/malware-campaign-at-youtube-uses-social.html' title='Malware campaign at YouTube uses social engineering tricks'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-5997630342373108332</id><published>2009-02-27T22:57:00.000-08:00</published><updated>2009-02-27T23:16:45.199-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Spam And Phishing'/><category scheme='http://www.blogger.com/atom/ns#' term='Patch Watch'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Data  theft'/><category scheme='http://www.blogger.com/atom/ns#' term='Anti Virus'/><category scheme='http://www.blogger.com/atom/ns#' term='Spyware and Adware'/><category scheme='http://www.blogger.com/atom/ns#' term='Arbitrary  Code  Execution'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Apple'/><category scheme='http://www.blogger.com/atom/ns#' term='Botnets'/><category scheme='http://www.blogger.com/atom/ns#' term='Firefox'/><title type='text'>Apple catches up on Safari (browser) security</title><content type='html'>&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=2675"&gt;&lt;img class="alignleft" src="http://blogs.zdnet.com/security/images/safari_browser.png" alt="" height="81" width="85" /&gt;&lt;/a&gt;After years of lagging behind on important security features, Apple has finally added a malware-blocker, a phishing filter and support for EV (extended validation) certificates into the latest refresh of its Safari Web browser.&lt;/p&gt; &lt;p&gt;The malware roadblock headlines a &lt;a href="http://www.apple.com/safari/features.html#security"&gt;list of Safari 4 security features&lt;/a&gt; that also includes cookie blocking, private browsing, secure encryption, safe downloads and parental controls.&lt;/p&gt; &lt;p&gt;&lt;span id="more-2675"&gt;&lt;/span&gt;&lt;br /&gt;&lt;strong&gt;[ SEE: &lt;a title="If a browser doesn't have anti-phishing technology (like Safari) ditch it" rel="bookmark" href="http://blogs.zdnet.com/security/?p=916"&gt;PayPal: If a browser doesn't have anti-phishing technology (like Safari) ditch it&lt;/a&gt; ]&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;Apple has been &lt;a href="http://blogs.zdnet.com/security/?p=916"&gt;heavily criticized in the past&lt;/a&gt; for neglecting basic security features in Safari.   PayPal CIO Michael Barrett &lt;a href="http://news.yahoo.com/s/infoworld/20080228/tc_infoworld/95634"&gt;went so far as to suggest&lt;/a&gt; that end users should avoid the browser because of the missing protections.&lt;/p&gt; &lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=2675"&gt;&lt;img class="size-full wp-image-2676 alignright" src="http://i.zdnet.com/blogs/apple_ev_cert.jpg" alt="" height="156" width="286" /&gt;&lt;/a&gt;&lt;/p&gt; &lt;p&gt;Now, it looks like Apple has finally caught up.

It covers a total of five vulnerabilities and affects Flash Player 10.0.12.36 and earlier&lt;/strong&gt;&lt;strong&gt; ]&lt;/strong&gt; &lt;p&gt;Sometime later today, Adobe will issue a patch for at least one critical vulnerability affecting its ubiquitous Flash Player.  If you live on the Windows ecosystem, this is a heads-up to pay attention to &lt;a href="http://www.adobe.com/support/security/"&gt;Adobe’s security updates page&lt;/a&gt; and treat this as a high-priority issue.&lt;/p&gt; &lt;p&gt;According to an advisory from iDefense, the company that brokered the disclosure process, the patch will fix a Flash Player vulnerability that could allow an attacker to use rigged Shockwave Flash files to execute arbitrary code with the privileges of the current user.&lt;/p&gt; &lt;p&gt;&lt;span id="more-2666"&gt;&lt;/span&gt;&lt;/p&gt; &lt;p&gt;From the &lt;a href="http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=773"&gt;iDefense alert&lt;/a&gt;:&lt;/p&gt; &lt;ul&gt;&lt;li&gt; During the processing of a Shockwave Flash file, a particular object can be created, along with multiple references that point to the object. The object can be destroyed and its associated references removed. However a reference can incorrectly remain pointing to the object. The invalid object resides in uninitialized memory, which the attacker may control to gain arbitrary execution control.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;To exploit this vulnerability, iDefense said a targeted user must load a malicious Shockwave Flash file created by an attacker.  This can be trivially done via social engineering techniques or injecting content into a compromised, trusted site or advertising network.&lt;/p&gt; &lt;ul&gt;&lt;li&gt; Utilizing various techniques, an attacker is able to re-allocate and control the memory used by the destroyed object. This allows the attacker to subvert execution when a virtual function is called via the invalid reference.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;The flaw was confirmed latest version of Flash Player (9.0.124.0). Previous versions may also be affected. iDefense said it tested exploitation on Windows XP SP3 and Windows Vista SP1.&lt;/p&gt; &lt;ul&gt;&lt;li&gt;iDefense believe that all platforms supported by Flash Player are affected by this vulnerability, including Linux and MacOS.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;Adobe was first notified of this issue last August.  The company is currently in the midst of &lt;a href="http://blogs.zdnet.com/security/?p=2631"&gt;responding to zero-day attacks&lt;/a&gt; against bugs in its Adobe Reader and Acrobat products.&lt;/p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;]&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-7950899023001632618?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/7950899023001632618/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=7950899023001632618' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/7950899023001632618'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/7950899023001632618'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/02/heads-up-critical-adobe-flash-player.html' title='Heads-up: Critical Adobe Flash Player patch coming'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-8544279447777677045</id><published>2009-02-27T21:33:00.000-08:00</published><updated>2009-02-27T21:58:40.958-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Passwords'/><category scheme='http://www.blogger.com/atom/ns#' term='Hackers'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><title type='text'>Chinese hackers deface the Russian Consulate in Shanghai</title><content type='html'>&lt;a href="http://blogs.zdnet.com/security/?p=2641#comments"&gt;&lt;span&gt;&lt;/span&gt;&lt;/a&gt;&lt;a href="http://i.zdnet.com/blogs/russia_consulate_china_defaced.jpg"&gt;&lt;img class="size-full wp-image-2642 alignleft" src="http://i.zdnet.com/blogs/russia_consulate_china_defaced.jpg" alt="" height="105" width="164" /&gt;&lt;/a&gt;That was fast. &lt;a href="http://www.thedarkvisitor.com/2009/02/chinese-hackers-take-down-russian-consulate-website/"&gt;Chinese hackers&lt;/a&gt; collaborating with the Chinese Hacking Union, a two-years old training community for wannabe hackers, hacked and defaced the official web site of  &lt;a href="http://www.rusconshanghai.org.cn/"&gt;the General Consulate of the Russian Federation in Shanghai, PRC&lt;/a&gt; in response to the recent accusations that a &lt;a href="http://www.telegraph.co.uk/news/worldnews/asia/china/4697845/Russian-navy-accused-of-sinking-Chinese-cargo-ship.html"&gt;Russian navy vessel has sank a Chinese cargo ship&lt;/a&gt;. &lt;p&gt;The message left on the now “under maintenance” site translates as follows:&lt;/p&gt; &lt;p&gt;&lt;span id="more-2641"&gt;&lt;/span&gt;&lt;/p&gt; &lt;blockquote&gt;&lt;p&gt;“Russia invaded our territory to kill people from the People’s Republic.

Symantec is continuing to monitor the vulnerability’s use in the wild.&lt;/p&gt; &lt;p&gt;While examining the JavaScript code used for “heap-spraying” in these PDFs, we can see the same comments that show that these separate exploit attempts come from the same source! It seems likely that the people behind this threat are using targeted attacks against high-ranking people within different organizations—for example, locating the CEO’s email address on the company website and sending a malicious PDF in the hope that their malicious payload will run. Once the machine is compromised, the attackers may gain access to sensitive corporate documents that could be costly for companies breached by this threat.&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;&lt;a href="http://i.zdnet.com/blogs/spy_protect_adobe_zeroday.jpg"&gt;&lt;img class="size-full wp-image-2634 alignleft" src="http://i.zdnet.com/blogs/spy_protect_adobe_zeroday.jpg" alt="" height="109" width="146" /&gt;&lt;/a&gt;For the time being, cybercriminals chose to generate less noise by launching targeted attacks just like they did earlier this week using &lt;a href="http://blogs.zdnet.com/security/?p=2607"&gt;IE7’s MS09-002 vulnerability&lt;/a&gt;. However, as we’ve previously seen it’s only a matter of time until copycat attackers start using it on a large scale.&lt;/p&gt; &lt;p&gt;With several targeted campaigns currently active, what are the chances that a sample malware campaign would be once again monetizing infected hosts by infecting them with rogue security software similar to &lt;a href="http://blogs.zdnet.com/security/?p=2388"&gt;Conficker’s first release&lt;/a&gt;? Huge.&lt;/p&gt; &lt;ul&gt;&lt;li&gt;Go through related incidents using Adobe exploits: &lt;a href="http://blogs.zdnet.com/security/?p=1815"&gt;MSN Norway serving Flash exploits through malvertising&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=1664"&gt;CNET’s Clientside developer blog serving Adobe Flash exploits&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=2142"&gt;Rigged PDFs exploiting just-patched Adobe Reader flaw&lt;/a&gt;&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;Upon analyzing the binary served once an infected host gets successfully exploited from a sample campaign, it’s attempting to trick the user into install the very latest rogue security software Spyware Protect 2009. The cute part is that the cybercriminals didn’t manage to successfully configure their campaign resulting in a 404 error.&lt;/p&gt; &lt;p&gt;What’s important to point out is that the original targeted attacks detected by the Shadowserver Foundation are once again using a well known and previously abused Chinese DNS provider (&lt;strong&gt;js001.3322.org&lt;/strong&gt;) with more details about its owner available in a &lt;a href="http://www.businessweek.com/magazine/content/08_16/b4080032218430_page_8.htm"&gt;related BusinessWeek article&lt;/a&gt;.&lt;/p&gt;&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;] &lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-8598141066100943407?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/8598141066100943407/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=8598141066100943407' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/8598141066100943407'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/8598141066100943407'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/02/adobe-reader-9-and-acrobat-9-zero-day.html' title='Adobe Reader 9 and Acrobat 9 zero day exploited in the wild'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-17002775651395336</id><published>2009-02-27T21:16:00.000-08:00</published><updated>2009-02-27T21:29:26.749-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Passwords'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Anti Virus'/><category scheme='http://www.blogger.com/atom/ns#' term='Hackers'/><category scheme='http://www.blogger.com/atom/ns#' term='Botnets'/><title type='text'>New Symbian-based mobile worm circulating in the wild</title><content type='html'>&lt;span style="display: none;" class="more"&gt;&lt;/span&gt;     &lt;script&gt;     var tb1 = new CNET.Blog.Toolbar.Interact();     CNET.Blog.Toolbar.Interact.allToolbars.push(tb1);     tb1.id = 'zdsecurity_2617';     CNET.Blog.Toolbar.Interact.service.contentId.push(tb1.id);     tb1.idContainer = 'interact_'+tb1.id;     tb1.title = 'New Symbian-based mobile worm circulating in the wild';     tb1.emailTitle = 'New Symbian-based mobile worm circulating in the wild | Zero Day | ZDNet.com';     tb1.diggTopic = 'tech_news';     tb1.diggBodyText = 'A ZDNET Blog';     tb1.absoluteUrl = 'http://blogs.zdnet.com/security/?p=2617';     tb1.relativeUrl = '?p=2617';     tb1.commentUrl = '?p=2617#comments';     tb1.blogThisUrl = 'index.php?blogthis=1&amp;p=2617';     tb1.noTalkback = '';     tb1.numTalkbacks = '';     tb1.votingId = tb1.id;     tb1.voteCount = 15;     tb1.voteTotal = 17;      tb1.recommend.hasVoted = false;     tb1.recommend.contentId = 'zdsecurity_2617';     tb1.recommend.userId = '';     tb1.recommend.encodedTitle = 'TmV3IFN5bWJpYW4tYmFzZWQgbW9iaWxlIHdvcm0gY2lyY3VsYXRpbmcgaW4gdGhlIHdpbGQ.';     tb1.recommend.encodedUrl = 'aHR0cDovL2Jsb2dzLnpkbmV0LmNvbS9zZWN1cml0eS8_cD0yNjE3';     tb1.recommend.rpcHost = 'blogs.zdnet.com';     tb1.recommend.loginUrl = 'http://www.zdnet.com/1320-4_24-44.html?path=';     tb1.recommend.returnUrl = 'http://blogs.zdnet.com/security/?p=2617';     tb1.recommend.cookieResults = '';     tb1.init();&lt;/script&gt;&lt;a href="http://i.zdnet.com/blogs/symbian.jpg"&gt;&lt;img class="size-full wp-image-2618 alignleft" src="http://i.zdnet.com/blogs/symbian.jpg" alt="" height="97" width="155" /&gt;&lt;/a&gt;F-Secure and &lt;a href="http://fortiguardcenter.com/advisory/FGA-2009-07.html"&gt;Fortinet are investigating&lt;/a&gt; a newly discovered &lt;a href="http://www.f-secure.com/weblog/archives/00001609.html"&gt;mobile malware&lt;/a&gt; identified as &lt;a href="http://www.fortiguardcenter.com/VirusEncyclopedia/search/encyclopediaSearch.do?method=quickSearchDirectly&amp;amp;virusName=SymbOS/Yxes.A%21worm"&gt;SymbOS/Yxes.A!worm&lt;/a&gt; or “Sexy View”. The malware is affecting &lt;span class="item"&gt;S60 3rd Edition series devices, and has a valid certificate signed by Symbian tricking the mobile device user into thinking it’s a legitimate application. In terms of propagation, “Sexy View” propagates by collecting all the phone numbers from the infected device, and then SMS-es itself to all of them including a link to a web site hosting a copy of it.&lt;br /&gt;&lt;/span&gt; &lt;p&gt;SymbOS/Yxes.A!worm is the second mobile malware detected in the wild for 2009, followed by last month’s discovery of &lt;a href="http://blogs.zdnet.com/security/?p=2415"&gt;Trojan-SMS.Python.Flocker&lt;/a&gt; by Kaspersky Labs. A trend, a fad, or opportunists experimenting for mobile malware’s prime time in 2009?&lt;/p&gt; &lt;p&gt;&lt;span id="more-2617"&gt;&lt;/span&gt;&lt;/p&gt; &lt;p&gt;Using spam and phishing as analogies, both, spammers and phishers require huge databases of harvested email address in order to hit them directly. What used to be old-fashioned directory attacks where they were attempting to guess user names and associate them with email boxes, is today’s &lt;a href="http://www.projecthoneypot.org/statistics.php"&gt;greatly matured underground market segment&lt;/a&gt; offering millions of segmented (on per country, city, industry, email provided basis) emails which cybecriminals easily integrate within their campaign management kits.&lt;/p&gt; &lt;p&gt;What’s particularly interesting about SymbOS/Yxes.A!worm is that it appears that the worm’s main objective is to harvest information from the infected devices such as phone numbers, IMEI, IMSI as well as the phone type. This data harvesting approach is pretty similar to that of email harvesting tools, and in the long term the harvested data will be monetized and resold to phone scammers whose activities are already driving the success of such site as &lt;a href="http://whocallsme.com/"&gt;WhoCallsme?&lt;/a&gt; and &lt;a href="http://800notes.com/"&gt;800notes&lt;/a&gt;.&lt;/p&gt; &lt;p&gt;Moreover, &lt;a href="http://fortiguardcenter.com/advisory/FGA-2009-07.html"&gt;Guillaume Lovet&lt;/a&gt;, a senior manager of Fortinet’s Threat Research Team is also speculating on the potential for a mobile botnet due to the ways in which Yxes.A!worm spreads: “&lt;em&gt;As far as our analysis goes, the worm currently does not take commands from the remote servers it contacts. However, since the copies hosted on the malicious servers are controlled by the cyber criminals, they may update them whenever they want, thereby effectively mutating the worm, adding or removing functionality. We’re really at the edge of a mobile botnet here.&lt;/em&gt;”&lt;/p&gt; &lt;p&gt;With carriers, manufacturers, and service providers clearly aware of the emerging mobile malware threat, thankfully, they seem to be thinking in the right direction - according to &lt;a href="http://www.mcafee.com/us/local_content/reports/mobile_security_report_2009.pdf"&gt;McAfee’s 2009’s Mobile Security Report&lt;/a&gt;, when asked “&lt;em&gt;Who Should Bear the Cost of Securing Mobile Devices?&lt;/em&gt;” 44% of the mobile device manufacturers forwarded the responsibility to themselves instead of their clients.&lt;/p&gt; &lt;p&gt;In times when your mobile number and physical location for a successful scam targeting is prone to become a valuable good in the underground economy, your vigilance remains a cost-effective solution.&lt;/p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;]&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-17002775651395336?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/17002775651395336/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=17002775651395336' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/17002775651395336'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/17002775651395336'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/02/new-symbian-based-mobile-worm.html' title='New Symbian-based mobile worm circulating in the wild'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-2809418787722838314</id><published>2009-02-17T21:13:00.000-08:00</published><updated>2009-02-17T21:16:18.448-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Windows Vista'/><category scheme='http://www.blogger.com/atom/ns#' term='Exploit Code'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Pen testing'/><category scheme='http://www.blogger.com/atom/ns#' term='Microsoft'/><category scheme='http://www.blogger.com/atom/ns#' term='Vulnerability Research'/><category scheme='http://www.blogger.com/atom/ns#' term='Complex Attacks'/><category scheme='http://www.blogger.com/atom/ns#' term='Patch Watch'/><category scheme='http://www.blogger.com/atom/ns#' term='DDos Attack'/><category scheme='http://www.blogger.com/atom/ns#' term='Data  theft'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Arbitrary  Code  Execution'/><category scheme='http://www.blogger.com/atom/ns#' term='Botnets'/><title type='text'>Microsoft: ‘Consistent exploit code likely’ for IE vulnerabilities</title><content type='html'>&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=2521"&gt;&lt;img class="alignleft" style="" src="http://blogs.zdnet.com/security/images/internet_explorer.png" alt="" height="107" width="101" /&gt;&lt;/a&gt;Microsoft today shipped four bulletins with patches for at least 8 documented security vulnerabilities affecting Windows users and warned that “consistent exploit code could be easily crafted” to launch attacks via the Internet Explorer browser.&lt;/p&gt; &lt;p&gt;The &lt;a href="http://www.microsoft.com/technet/security/Bulletin/MS09-feb.mspx"&gt;Patch Tuesday batch&lt;/a&gt; includes fixes for a pair of code execution holes in IE, two bugs in the Microsoft Exchange Server, a remote code execution issue in the Microsoft SQL Server, and three separate flaws haunting users of Microsoft Office Visio.&lt;/p&gt; &lt;p&gt;&lt;span id="more-2521"&gt;&lt;/span&gt;&lt;/p&gt; &lt;p&gt;The Internet Explorer bulletin (&lt;a href="http://www.microsoft.com/technet/security/Bulletin/MS09-002.mspx"&gt;MS09-002&lt;/a&gt;) should be treated with urgency because the flaws can be exploited to launch drive-by download attacks.&lt;/p&gt; &lt;ul&gt;&lt;li&gt;This security update is rated Critical for Internet Explorer 7 running on supported editions of Windows XP and Windows Vista. For Internet Explorer 7 running on supported editions of Windows Server 2003 and Windows Server 2008, this security update is rated Moderate.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;The Microsoft warning that consistent exploit code was likely suggests that it’s very easy for an attacker to host a specially crafted Web site and attack unpatched users who surfed to the rigged Web site.&lt;/p&gt; &lt;ul&gt;&lt;li&gt;The attacker could also take advantage of compromised Web sites and Web sites that accept or host user-provided content or advertisements. These Web sites could contain specially crafted content that could exploit this vulnerability.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;Enterprise administrators will also want to pay special attention to the Microsoft Exchange update (&lt;a href="http://www.microsoft.com/technet/security/Bulletin/MS09-003.mspx"&gt;MS09-003&lt;/a&gt;) which covers two different vulnerabilities that expose users to code execution or denial-of-service attacks.&lt;/p&gt; &lt;p&gt;Microsoft explains:&lt;/p&gt; &lt;ul&gt;&lt;li&gt;The first vulnerability could allow remote code execution if a specially crafted TNEF message is sent to a Microsoft Exchange Server. An attacker who successfully exploited this vulnerability could take complete control of the affected system with Exchange Server service account privileges. The second vulnerability could allow denial of service if a specially crafted MAPI command is sent to a Microsoft Exchange Server. An attacker who successfully exploited this vulnerability could cause the Microsoft Exchange System Attendant service and other services that use the EMSMDB32 provider to stop responding.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;The company says it expects to see “inconsistent exploit code” published for this bulletin.  However, nCircle director of security operations Andrew Storms says this is a very serious problem.&lt;em&gt;&lt;br /&gt;&lt;/em&gt;&lt;/p&gt; &lt;p&gt;“This vulnerability means that any cybercriminal sending a well crafted email attachment to an enterprise could gain complete control over the server and gaining one of the keys to the kingdom,” Storms said.&lt;/p&gt; &lt;p&gt;“All kinds of highly confidential and proprietary information pass through an Exchange server every day.  Gaining control over it and its content would be a gold mine to any cyber criminal,” he added.&lt;/p&gt;&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;] &lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-2809418787722838314?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/2809418787722838314/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=2809418787722838314' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/2809418787722838314'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/2809418787722838314'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/02/microsoft-consistent-exploit-code_17.html' title='Microsoft: ‘Consistent exploit code likely’ for IE vulnerabilities'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-6071406668121958558</id><published>2009-02-17T21:08:00.000-08:00</published><updated>2009-02-17T21:12:29.266-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Passwords'/><category scheme='http://www.blogger.com/atom/ns#' term='Exploit Code'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Anti Virus'/><category scheme='http://www.blogger.com/atom/ns#' term='Arbitrary  Code  Execution'/><category scheme='http://www.blogger.com/atom/ns#' term='Hackers'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Microsoft'/><category scheme='http://www.blogger.com/atom/ns#' term='Botnets'/><title type='text'>Targeted malware attacks exploiting IE7 flaw detected</title><content type='html'>&lt;a href="http://blogs.zdnet.com/security/?p=2607#comments"&gt;&lt;span&gt;&lt;/span&gt;&lt;/a&gt;&lt;a href="http://i.zdnet.com/blogs/internet_explorer_7_logo.png"&gt;&lt;img class="size-full wp-image-2608 alignleft" src="http://i.zdnet.com/blogs/internet_explorer_7_logo.png" alt="" height="105" width="105" /&gt;&lt;/a&gt;Researchers at &lt;a href="http://blog.trendmicro.com/another-exploit-targets-ie7-bug/"&gt;TrendMicro have detected a targeted malware attack&lt;/a&gt; exploiting last week’s patched &lt;a href="http://www.microsoft.com/technet/security/Bulletin/MS09-002.mspx"&gt;critical MS09-002 vulnerability affecting Internet Explorer 7&lt;/a&gt;.  Upon opening the spammed Microsoft office document, vulnerable users are automatically forwarded to a Chinese &lt;a href="http://www.virustotal.com/analisis/577b04ed88784ca07fc5e97f945b424e"&gt;live exploit site&lt;/a&gt; which still &lt;a href="http://www.virustotal.com/analisis/5a028710a513ba50bab70c3e7b9ebf41"&gt;remains active&lt;/a&gt;. &lt;p&gt;The attack has also been &lt;a href="http://www.avertlabs.com/research/blog/index.php/2009/02/17/ms09-002-exploit-in-the-wild-uses-msword-lure/"&gt;confirmed by McAfee&lt;/a&gt; and &lt;a href="http://isc.sans.org/diary.php?storyid=5884"&gt;by the ISC&lt;/a&gt;, who point out that the cybercriminals appear to have reverse engineered Microsoft’s patch in order to come up with the exploit.&lt;/p&gt; &lt;p&gt;From TrendMicro’s post:&lt;/p&gt; &lt;p&gt;&lt;span id="more-2607"&gt;&lt;/span&gt;&lt;/p&gt; &lt;blockquote&gt;&lt;p&gt;The threat starts with a spammed malicious .DOC file detected as XML_DLOADR.A. This file has a very limited distribution script, suggesting it may be a targeted attack. It contains an ActiveX object that automatically accesses a site rigged with a malicious HTML detected by the Trend Micro Smart Protection Network as HTML_DLOADER.AS.&lt;/p&gt; &lt;p&gt;HTML_DLOADER.AS exploits the CVE-2009-0075 vulnerability, which is already addressed by the MS09-002 security patch released last week. On an unpatched system though, successful exploitation by HTML_DLOADER.AS downloads a backdoor detected as BKDR_AGENT.XZMS.&lt;/p&gt; &lt;p&gt;This backdoor further installs a .DLL file that has information stealing capabilities. It sends its stolen information to another URL via port 443.&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;The attackers trade-off in this case is to either launch a less noisy targeted attack, or attempt to target as many users as possible by using legitimate web sites as infection vectors, a choice that depends on what they’re trying to achieve, and who are they targeting in particular.&lt;/p&gt; &lt;p&gt;Who’s behind the attack anyway? The web service (&lt;strong&gt;9966.org&lt;/strong&gt;) used as a “phone back” location with the stolen data, is a well known one used primarily by Chinese hackers in previous massive SQL injections attacks, which doesn’t necessarily mean the campaign is launched by Chinese hackers, since it could be international hackers from anywhere using a well known malicious infrastructure in order to forward the responsibility to local hackers.&lt;/p&gt; &lt;p&gt;Moreover, in this particular campaign I can easily argue that the window of opportunity for abusing this vulnerability in a targeted fashion, is just as wide open as &lt;a href="http://blogs.zdnet.com/security/?p=2517"&gt;attempting to exploit the same hosts by diversifying the use of different exploits&lt;/a&gt;. For instance, despite the timely exploitation of MS09-002, based on the &lt;a href="http://blogs.zdnet.com/security/?p=2388"&gt;number of Conficker affected hosts globally&lt;/a&gt;, a situation where once again a patch is present, there’s a great chance that some of the hosts they’re attempting to exploit through the use of MS09-002 are already part of Conficker’s botnet, or remain susceptible to outdated vulnerabilities.&lt;/p&gt; &lt;p&gt;So far, no massive malware campaigns are taking advantage of the exploit, but users are advised to &lt;a href="http://secunia.com/vulnerability_scanning/online/"&gt;self-audit themselves&lt;/a&gt; against known client-side vulnerabilities and &lt;a href="http://www.microsoft.com/technet/security/Bulletin/MS09-002.mspx"&gt;MS09-002&lt;/a&gt; in particular.&lt;/p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;]&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-6071406668121958558?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/6071406668121958558/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=6071406668121958558' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/6071406668121958558'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/6071406668121958558'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/02/targeted-malware-attacks-exploiting-ie7.html' title='Targeted malware attacks exploiting IE7 flaw detected'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-7736856153748613581</id><published>2009-02-17T21:03:00.000-08:00</published><updated>2009-02-17T21:08:19.976-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Passwords'/><category scheme='http://www.blogger.com/atom/ns#' term='DDos Attack'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Anti Virus'/><category scheme='http://www.blogger.com/atom/ns#' term='Hackers'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Botnets'/><title type='text'>Crimeware tracking service hit by a DDoS attack</title><content type='html'>&lt;a href="http://blogs.zdnet.com/security/?p=2596#comments"&gt;&lt;span&gt;&lt;/span&gt;&lt;/a&gt;&lt;a href="http://i.zdnet.com/blogs/abusechddos.jpg"&gt;&lt;img class="size-full wp-image-2599 alignleft" src="http://i.zdnet.com/blogs/abusechddos.jpg" alt="" height="87" width="173" /&gt;&lt;/a&gt;A week after a &lt;a href="http://www.abuse.ch/?p=1037"&gt;newly launched crimeware tracking service&lt;/a&gt; went public, cybercriminals didn’t hesitate to prove its usefulness by &lt;a href="http://www.abuse.ch/?p=1065"&gt;launching a distributed denial of service attack (DDoS) against it.&lt;/a&gt; According to the Swiss security blog, the Zeus tracker came under attack from a previously known source that also attacked &lt;strong&gt;abuse.ch&lt;/strong&gt; over an year ago taking advantage of a well known do-it-yourself DDoS malware. &lt;p&gt;Just like November 2008’s &lt;a href="http://blogs.zdnet.com/security/?p=2188"&gt;DDoS attack against the anti-fraud site Bobbear.co.uk&lt;/a&gt; — with evidence that the attack was commissioned &lt;a href="http://blogs.zdnet.com/security/images/ddos_for_hire_bobbear.png"&gt;provided by Zero Day&lt;/a&gt; back then — the single most evident proof of the usefulness of your cybercrime tracking service always comes in the form of a direct attack against its availability.&lt;/p&gt; &lt;p&gt;What is &lt;a href="https://zeustracker.abuse.ch/monitor.php?filter=online"&gt;the Zeus Tracker&lt;/a&gt; anyway, and why is it so special at the first place?&lt;/p&gt; &lt;p&gt;&lt;span id="more-2596"&gt;&lt;/span&gt;&lt;/p&gt; &lt;p&gt;&lt;a href="http://i.zdnet.com/blogs/crimeware_on_demand_3.jpg"&gt;&lt;img class="size-full wp-image-2603 alignleft" src="http://i.zdnet.com/blogs/crimeware_on_demand_3.jpg" alt="" height="58" width="199" /&gt;&lt;/a&gt;The Zeus Tracker is a full-disclosure project keeping track of known Zeus hosting locations, &lt;a href="http://ddanchev.blogspot.com/2008/04/crimeware-in-middle-zeus.html"&gt;one of the most ubiquitous crimeware applications&lt;/a&gt; cybercriminals take advantage of for years. Moreover, by maintaining &lt;a href="https://zeustracker.abuse.ch/blocklist.php"&gt;a real-time blocklist&lt;/a&gt; that allows the community to easily take action against known Zeus domains/IPs it shouldn’t come as a surprise that the service is getting attacked - simply because it exposes active crimeware campaigns.&lt;/p&gt; &lt;ul&gt;&lt;li&gt;Go through more recent DDoS attacks coverage - &lt;a href="http://blogs.zdnet.com/security/?p=2391"&gt;GoDaddy hit by a DDoS attack&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=2240"&gt;AlertPay hit by a large scale DDoS attack&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=2162"&gt;BBC hit by a DDoS attack&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=2188"&gt;Anti fraud site hit by a DDoS attack&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=1935"&gt;Norwegian BitTorrent tracker under DDoS attack&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=1533"&gt;Georgia President’s web site under DDoS attack from Russian hackers&lt;/a&gt;&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;Once available as a proprietary crimeware tool costing several thousands dollars, today, pirated copies of Zeus are so prevalent, that most of the innovations attempting to to improve its usefulness and abilities to sniff E-banking transaction data come from third parties in a true open source crimeware fashion. In fact, the Zeus crimeware is so popular that cybercriminals themselves are looking for and successfully finding &lt;a href="http://ddanchev.blogspot.com/2008/06/zeus-crimeware-kit-vulnerable-to.html"&gt;remotely exploitable vulnerabilities within the kit&lt;/a&gt; in an attempt to hijack someone else’s botnet.&lt;/p&gt; &lt;p&gt;Moreover, with or without the Zeus Tracker’s real-time data, the Zeus malware is prone to continue dominating the crimeware landscape due to its maturity into a &lt;a href="http://4.bp.blogspot.com/_wICHhTiQmrA/STwStz7muCI/AAAAAAAACg4/i4crX4aT7mc/s1600-h/crimeware_on_demand_service.JPG"&gt;cybercrime-as-a-service proposition&lt;/a&gt;. For instance, the increasing number of services offering managed Zeus botnets not only allow less sophisticated cybercriminals easy access to hundreds of thousands of banker malware infected hosts, but also, the relatively low prices the services charge due to the fact that they’re running pirated copies of Zeus ultimately results in the scalability of cybercrime in general.&lt;/p&gt; &lt;p&gt;Attempting to undermine this scalability would mean coming up with ways to shorten the average time a Zeus command and control domain/IP remains online, next to communicating the already known locations as a public service just like &lt;a href="https://zeustracker.abuse.ch/monitor.php?filter=online"&gt;the Zeus Tracker&lt;/a&gt; does.&lt;/p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;]&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-7736856153748613581?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/7736856153748613581/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=7736856153748613581' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/7736856153748613581'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/7736856153748613581'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/02/crimeware-tracking-service-hit-by-ddos.html' title='Crimeware tracking service hit by a DDoS attack'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-5034558081577566205</id><published>2009-02-14T05:05:00.000-08:00</published><updated>2009-02-14T05:09:11.461-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Patch Watch'/><category scheme='http://www.blogger.com/atom/ns#' term='Exploit Code'/><category scheme='http://www.blogger.com/atom/ns#' term='DDos Attack'/><category scheme='http://www.blogger.com/atom/ns#' term='Data  theft'/><category scheme='http://www.blogger.com/atom/ns#' term='Arbitrary  Code  Execution'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Apple'/><category scheme='http://www.blogger.com/atom/ns#' term='Microsoft'/><title type='text'>Apple Patch Day: Gaping Mac OS X, Safari holes</title><content type='html'>&lt;a href="http://blogs.zdnet.com/security/?p=2577#comments"&gt;&lt;span&gt;&lt;/span&gt;&lt;/a&gt;&lt;a href="http://blogs.zdnet.com/security/?p=2577"&gt;&lt;img class="size-full wp-image-2583 alignleft" src="http://i.zdnet.com/blogs/appl_software_update_icon.jpg" alt="" height="89" width="97" /&gt;&lt;/a&gt;It’s Apple’s turn on the Patch Day treadmill and, for Mac OS X users, it’s quite ugly. &lt;p&gt;As I write, Apple has released four different bulletins to cover 48 documented vulnerabilities in the Mac OS X ecosystem, a solitary code execution flaw affecting Safari for Windows and four different security problems in Java for Mac OS X.&lt;/p&gt; &lt;p&gt;&lt;span id="more-2577"&gt;&lt;/span&gt;Security Update 2009-001 is quite a whopper, providing patches for holes in a wide range of components, including several open-source implementations like ClamAV and fetchmail.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;[ &lt;a title="Permanent Link to How does Apple get away with this badware behavior?" rel="bookmark" href="http://blogs.zdnet.com/security/?p=1335"&gt;How does Apple get away with this badware behavior?&lt;/a&gt; ]&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;This is a high-priority update for all Mac OS X users so don’t fool around when you see that Software Update alert.

Typically we are reluctant to elevate one vulnerability over the other, however looking at the 2008 data we agree that Internet Explorer vulnerabilities should be given the highest priority and patched first. The browser is the heaviest used software application that interacts with the Internet, the most likely source of malicious content. It is not only used for professional purposes but also in private interactions – e-commerce, social networking, private e-mail, etc. Browser patches are heavily tested by Microsoft and unlikely to break any existing functionality on the desktop.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;Unfortunately, Kandek says the vulnerability data shows that companies treat browser patches just like all other patches — their deployment cycle correlates very closely with other critical patches.&lt;/p&gt; &lt;p&gt;The answer?   Kandek argues that Microsoft should borrow from the Mozilla Firefox playbook and fit an automatic-update utility directly into IE to handle patching on the fly.&lt;/p&gt; &lt;p&gt;“Think about it.  There’s a very big exposure area.  Hackers are increasingly targeting the browser. Enterprises are on a tight patch schedule.  If IE got moved out of Patch Tuesday, won’t it be better?” he added.&lt;strong&gt;&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;&lt;strong&gt;[ GALLERY: &lt;a href="http://content.zdnet.com/2346-12691_22-87874-1.html"&gt;How to configure Internet Explorer to run securely&lt;/a&gt; ] &lt;/strong&gt;&lt;/p&gt; &lt;p&gt;“Patches would be deployed faster and we would have a healthier IE population,” Kandek added, nothing that IE add-ons like Flash and other media players would benefit from an automatic update tool embedded in the browser.&lt;/p&gt; &lt;p&gt;The Qualys data was culled from 9.5 million IP scans per month.&lt;/p&gt; &lt;p&gt;&lt;em&gt;* Hat tip to &lt;a href="http://www.computerworld.com/action/article.do?command=viewArticleBasic&amp;amp;articleId=9127753&amp;amp;source=rss_topic17"&gt;Gregg Keizer&lt;/a&gt; at ComputerWorld.&lt;/em&gt;&lt;/p&gt;&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;] &lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-2775926660176574253?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/2775926660176574253/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=2775926660176574253' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/2775926660176574253'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/2775926660176574253'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/02/should-microsoft-decouple-ie-from-patch.html' title='Should Microsoft decouple IE from Patch Tuesday?'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-3673980531463389546</id><published>2009-02-11T21:35:00.000-08:00</published><updated>2009-02-11T21:37:38.574-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Passwords'/><category scheme='http://www.blogger.com/atom/ns#' term='Spam And Phishing'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Anti Virus'/><category scheme='http://www.blogger.com/atom/ns#' term='Hackers'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Botnets'/><title type='text'>Massive comment spam attack on Digg.com leads to malware</title><content type='html'>&lt;a href="http://blogs.zdnet.com/security/?p=2544#comments"&gt;&lt;span&gt;&lt;/span&gt;&lt;/a&gt;&lt;a href="http://i.zdnet.com/blogs/digg_fake_codec_malware3.jpg"&gt;&lt;img class="size-full wp-image-2545 alignleft" src="http://i.zdnet.com/blogs/digg_fake_codec_malware3.jpg" alt="" height="80" width="162" /&gt;&lt;/a&gt;According to PandaSecurity, &lt;a href="http://pandalabs.pandasecurity.com/archive/Have-you-ever-heard-the-term-_2200_Rickrolling_22003F00_-Malware-distributors-have_2E002E002E00_.aspx"&gt;the social news site Digg.com&lt;/a&gt; is among the very latest Web 2.0 services to be targeted by cybecriminals on their way to acquire legitimate traffic to their malware serving domains. The ongoing attack is far more widespread the originally stated, with +500,000 bogus comments&lt;br /&gt;&lt;p&gt; leading to 15 currently active malware domains, where the end user is enticed to install a &lt;a href="http://www.virustotal.com/analisis/35a4eb801b1ea42b9260d268e6e7d85a"&gt;fake video codec&lt;/a&gt; in order to view the video. Once executed, &lt;a href="http://www.virustotal.com/analisis/3662a950f3e285f7bd83da6de4c7b256"&gt;the codec attempts&lt;/a&gt; to trick the user that they’re &lt;a href="http://www.virustotal.com/analisis/2f3ed92d5983b635e71d99700d6a42af"&gt;infected with malware&lt;/a&gt;, and in order to get rid of it, a &lt;a href="http://www.virustotal.com/analisis/d2ee81166ee0cc9422285f47ddf76421"&gt;rogue security software&lt;/a&gt; has to be purchased.&lt;/p&gt; &lt;p&gt;Despite the obvious similarities with &lt;a href="http://blogs.zdnet.com/security/?p=2433"&gt;last month’s Google Video keywords poisoning attack&lt;/a&gt;, the comment-spam campaign at Digg.com is unique in the sense that it appears to have been active for over an year now. Let’s dissect the campaign, and explain how it works.&lt;/p&gt; &lt;p&gt;&lt;span id="more-2544"&gt;&lt;/span&gt;&lt;/p&gt; &lt;p&gt;&lt;a href="http://i.zdnet.com/blogs/digg_fake_codec_malware.jpg"&gt;&lt;img class="size-full wp-image-2548 alignleft" src="http://i.zdnet.com/blogs/digg_fake_codec_malware.jpg" alt="" height="142" width="131" /&gt;&lt;/a&gt;The cybercriminals are taking advantage of on purposely registrated bogus accounts, in a combination with compromised legitimate accounts to not only post Digg stories directly leading to malware, but also, to heavily comment on legitimate and bogus stories by posting even more malware-serving links.&lt;/p&gt; &lt;p&gt;So basically, you have a catchy title submitted through a bogus account, with a miltitude of bogus accounts commenting on it, and linking to more malware serving domains. Or exactly the opposite - bogus accounts commenting on legitimate stories since January, 2008. This practice of self-recommendation greatly reminds me a &lt;a href="http://www.fortiguardcenter.com/reports/roundup_july_2006.html"&gt;similar Ebay bot talk scheme back in 2006&lt;/a&gt;, where bogus accounts were automatically giving positive recommendation to fraudulent accounts, all operated by the same person/gang.&lt;/p&gt; &lt;ul&gt;&lt;li&gt;Go through related abuse of Web 2.0 services by cybercriminals: &lt;a href="http://blogs.zdnet.com/security/?p=2358"&gt;Bogus LinkedIn profiles serving malware&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=2097"&gt;Spammers targeting Bebo, generate thousands of bogus accounts&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=1852"&gt;Malware and spam attacks exploiting Picasa and ImageShack&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=1640"&gt;Twitter being used to distribute malware&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=1995"&gt;Cybercriminals syndicating Google Trends keywords to serve malware&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=2405"&gt;Malware-infected WinRAR distributed through Google AdWords&lt;/a&gt;&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;&lt;a href="http://i.zdnet.com/blogs/digg_fake_codecs_malware.jpg"&gt;&lt;img class="size-full wp-image-2549 alignleft" src="http://i.zdnet.com/blogs/digg_fake_codecs_malware.jpg" alt="" height="115" width="141" /&gt;&lt;/a&gt;Interestingly, just like in Google’s keywords poisoning campaign, no client-side vulnerabilities are used.

Hackers have already &lt;a href="http://blogs.zdnet.com/security/?p=2067"&gt;successfully infiltrated the iPhone and Android platforms&lt;/a&gt; and there are known security problems in Symbian and Windows Mobile so we’re likely to see a lot of attention paid to this contest.&lt;/p&gt; &lt;p&gt;In 2007, New York-based security researcher Dino Dai Zovi teamed up with Shane Macaulay to &lt;a href="http://blogs.zdnet.com/security/?p=177"&gt;hijack a MacBook Pro via a flaw in Apple’s QuickTime software&lt;/a&gt;.    A year later, hacker Charlie Miller needed just two minutes to &lt;a href="http://dvlabs.tippingpoint.com/blog/2008/03/27/day-two-of-cansecwest-pwn-to-own---we-have-our-first-official-winner-with-picture"&gt;exploit a Safari bug&lt;/a&gt; to win that contest.&lt;/p&gt; &lt;p&gt;Alex Sotirov also partnered with Macaulay in 2008 to exploit an Adobe Flash vulnerability on a Windows Vista box.

Two critical items were released — including patches for Internet Explorer 7 and Microsoft Exchange Server.  Additionally, two “important” items were released — for Microsoft SQL Server and Visio.&lt;/p&gt; &lt;p&gt;MS09-002 is a typical IE patch, providing protection if a user is surfing to an evil website.  What’s unusual this month is that the vulnerability is only present in Internet Explorer 7.  This leads to the question “what did Microsoft put in IE7 that they didn’t put in earlier versions that leads to this exploit, and why didn’t their new security testing program catch this vulnerability?”&lt;/p&gt; &lt;p&gt;&lt;span id="more-2529"&gt;&lt;/span&gt;&lt;br /&gt;&lt;strong&gt;[ SEE: &lt;a title="‘Consistent exploit code likely’ for IE vulnerabilities" rel="bookmark" href="http://blogs.zdnet.com/security/?p=2521"&gt;Microsoft: ‘Consistent exploit code likely’ for IE vulnerabilities&lt;/a&gt; ]&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;Microsoft says that it’s easy for hackers to create an evil webpage to exploit this issue.&lt;/p&gt; &lt;p&gt;MS09-003 is a Critical patch for Exchange Server (versions 2000, 2003, 2007) that could lead to code execution and/or Denial of Service.  The attacker can send a malformed winmail.dat file to an Exchange Server in hopes of having that server execute code of their choosing.  (winmail.dat files are configuration files that instruct the email client how to render and display Rich Text Formatted documents.)  Alternatively, the attacker can send a series of packets to the Exchange Server in an attempt to take down the mail services - creating a denial of service attack.  Microsoft says that inconsistent exploit code is likely to be released.&lt;/p&gt; &lt;p&gt;MS09-004 is probably the most interesting patch this month.  This patch addresses the &lt;a href="http://blogs.zdnet.com/security/?p=2333"&gt;zero-day SQL Server flaw&lt;/a&gt; reported &lt;a href="http://www.sec-consult.com/files/20081209_mssql-sp_replwritetovarbin_memwrite.txt"&gt;by Sec-Consult&lt;/a&gt; on December 9th, 2008.  This flaw enables attackers to execute code of their choice on the affected SQL Server.  The bar for exploitation is raised slightly in that the attacker must already have authenticated access to the SQL Server in order to pull of this exploit.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;[ SEE: &lt;a title="Permanent Link to Microsoft confirms critical SQL Server vulnerability" rel="bookmark" href="http://blogs.zdnet.com/security/?p=2333"&gt;Microsoft confirms critical SQL Server vulnerability&lt;/a&gt; ]&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;However, unauthenticated attackers (since when you do authenticate your attacker anyway?) can still leverage this flaw if they can plant their code using SQL Server injection techniques via poorly coded websites.  Proof of concept code has been published on the Internet but Microsoft says they have not seen proof of exploitation (maybe they aren’t looking hard enough?).  I’d probably rate this patch as Critical - given the end result capable.  I’m guessing Microsoft has downgraded this severity because of the “authentication” requirement. (although they give this a ‘1′ in the exploitability index - saying that consistent exploit code is likely).&lt;/p&gt; &lt;p&gt;MS09-005 is an Important patch for Visio.  Open a malformed Visio document and the evil-doer can run code on your system in the context of your currently logged on account.  Microsoft says this was privately reported and they’ve seen no reports of exploitation.  They recommend not opening Visio documents from untrusted sources.&lt;strong&gt;&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;&lt;strong&gt;[ SEE: &lt;a title="Permanent Link to BlackBerry bitten by ActiveX control flaw" rel="bookmark" href="http://blogs.zdnet.com/security/?p=2524"&gt;BlackBerry bitten by ActiveX control flaw&lt;/a&gt; ]&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;I recommend a two pronged approach to patching this month.  Two patches are for Server issues (09-003 and 4 - Exchange and SQL) and two are for client side applications (09-002 and 5 - IE7 and Visio).  Give the two server patches to the Server maintenance team and ask that they install these two as soon as possible - given what I believe is the severity of these issues.  Give the two client side patches to the desktop team and have them install these patches in the next update cycle or as they see fit - but no need to burn the weekend candle for these.&lt;/p&gt; &lt;p&gt;&lt;em&gt;* Eric Schultze is chief technology officer at Shavlik Technologies, a vulnerability management company.&lt;/em&gt;&lt;/p&gt;&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;] &lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-103177955190540501?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/103177955190540501/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=103177955190540501' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/103177955190540501'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/103177955190540501'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/02/inside-microsofts-february-patch-batch.html' title='Inside Microsoft’s February patch batch'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-641786373389911297</id><published>2009-02-11T21:15:00.000-08:00</published><updated>2009-02-11T21:19:55.806-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Vulnerability Research'/><category scheme='http://www.blogger.com/atom/ns#' term='Patch Watch'/><category scheme='http://www.blogger.com/atom/ns#' term='Exploit Code'/><category scheme='http://www.blogger.com/atom/ns#' term='DDos Attack'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Data  theft'/><category scheme='http://www.blogger.com/atom/ns#' term='Arbitrary  Code  Execution'/><category scheme='http://www.blogger.com/atom/ns#' term='Pen testing'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><title type='text'>BlackBerry bitten by ActiveX control flaw</title><content type='html'>&lt;a href="http://blogs.zdnet.com/security/?p=2524#comments"&gt;&lt;span&gt;&lt;/span&gt;&lt;/a&gt;&lt;a href="http://blogs.zdnet.com/security/?p=2524"&gt;&lt;img class="alignleft size-full wp-image-2525" src="http://i.zdnet.com/blogs/blackberry_logo.jpg" alt="" height="38" width="140" /&gt;&lt;/a&gt;Research in Motion (RIM) today raised an alarm for a serious security vulnerability in the BlackBerry Application Web Loader, warning that it exposes Windows users to code execution attacks. &lt;p&gt;&lt;span id="more-2524"&gt;&lt;/span&gt;&lt;/p&gt; &lt;ul&gt;&lt;li&gt;When a BlackBerry device user browses to a web site that is designed to install the BlackBerry Application Web Loader ActiveX control on BlackBerry devices over a USB connection, and clicks Yes to install and run the ActiveX control, the ActiveX control introduces the vulnerability to the computer.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;An &lt;a href="http://www.us-cert.gov/current/index.html#blackberry_security_advisory1"&gt;advisory&lt;/a&gt; from US-CERT explains that a malicious hacker could use booby-trapped HTML documents or Web pages to execute arbitrary code with the privileges of the user.

includes fixes for a pair of code execution holes in IE, two bugs in the Microsoft Exchange Server, a remote code execution issue in the Microsoft SQL Server, and three separate flaws haunting users of Microsoft Office Visio.&lt;/p&gt; &lt;p&gt;&lt;span id="more-2521"&gt;&lt;/span&gt;&lt;/p&gt; &lt;p&gt;The Internet Explorer bulletin (&lt;a href="http://www.microsoft.com/technet/security/Bulletin/MS09-002.mspx"&gt;MS09-002&lt;/a&gt;) should be treated with urgency because the flaws can be exploited to launch drive-by download attacks.&lt;/p&gt; &lt;ul&gt;&lt;li&gt;This security update is rated Critical for Internet Explorer 7 running on supported editions of Windows XP and Windows Vista. For Internet Explorer 7 running on supported editions of Windows Server 2003 and Windows Server 2008, this security update is rated Moderate.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;The Microsoft warning that consistent exploit code was likely suggests that it’s very easy for an attacker to host a specially crafted Web site and attack unpatched users who surfed to the rigged Web site.&lt;/p&gt; &lt;ul&gt;&lt;li&gt;The attacker could also take advantage of compromised Web sites and Web sites that accept or host user-provided content or advertisements. These Web sites could contain specially crafted content that could exploit this vulnerability.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;Enterprise administrators will also want to pay special attention to the Microsoft Exchange update (&lt;a href="http://www.microsoft.com/technet/security/Bulletin/MS09-003.mspx"&gt;MS09-003&lt;/a&gt;) which covers two different vulnerabilities that expose users to code execution or denial-of-service attacks.&lt;/p&gt; &lt;p&gt;Microsoft explains:&lt;/p&gt; &lt;ul&gt;&lt;li&gt;The first vulnerability could allow remote code execution if a specially crafted TNEF message is sent to a Microsoft Exchange Server. An attacker who successfully exploited this vulnerability could take complete control of the affected system with Exchange Server service account privileges. The second vulnerability could allow denial of service if a specially crafted MAPI command is sent to a Microsoft Exchange Server. An attacker who successfully exploited this vulnerability could cause the Microsoft Exchange System Attendant service and other services that use the EMSMDB32 provider to stop responding.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;The company says it expects to see “inconsistent exploit code” published for this bulletin.  However, nCircle director of security operations Andrew Storms says this is a very serious problem.&lt;em&gt;&lt;br /&gt;&lt;/em&gt;&lt;/p&gt; &lt;p&gt;“This vulnerability means that any cybercriminal sending a well crafted email attachment to an enterprise could gain complete control over the server and gaining one of the keys to the kingdom,” Storms said.&lt;/p&gt; &lt;p&gt;“All kinds of highly confidential and proprietary information pass through an Exchange server every day.  Gaining control over it and its content would be a gold mine to any cyber criminal,” he added.&lt;/p&gt;&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;] &lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-3343669549761608178?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/3343669549761608178/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=3343669549761608178' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/3343669549761608178'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/3343669549761608178'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/02/microsoft-consistent-exploit-code.html' title='Microsoft: ‘Consistent exploit code likely’ for IE vulnerabilities'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-6469089161755305470</id><published>2009-02-11T21:00:00.000-08:00</published><updated>2009-02-11T21:10:41.462-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Windows Vista'/><category scheme='http://www.blogger.com/atom/ns#' term='Passwords'/><category scheme='http://www.blogger.com/atom/ns#' term='Patch Watch'/><category scheme='http://www.blogger.com/atom/ns#' term='Black Hat  Hackers'/><category scheme='http://www.blogger.com/atom/ns#' term='Exploit Code'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Arbitrary  Code  Execution'/><category scheme='http://www.blogger.com/atom/ns#' term='Pen testing'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Botnets'/><title type='text'>Report: 92% of critical Microsoft vulnerabilities mitigated by Least Privilege accounts</title><content type='html'>&lt;a href="http://i.zdnet.com/blogs/windows_generic_v_web.jpg"&gt;&lt;img class="size-full wp-image-2518 alignleft" src="http://i.zdnet.com/blogs/windows_generic_v_web.jpg" alt="" height="89" width="128" /&gt;&lt;/a&gt;A recently &lt;a href="http://www.beyondtrust.com/company/pressreleases/03Feb2009.aspx"&gt;released report&lt;/a&gt; by BeyondTrust entitled “&lt;a href="http://www.beyondtrust.com/documentation/whitePapers/wp_VulnerabilityReport.pdf"&gt;Reducing the Threat from Microsoft Vulnerabilities&lt;/a&gt;” indicates that that according to the company’s analysis of all the security bulletins Microsoft published in 2008, 92% of the critical vulnerabilities could have been mitigated by the &lt;a href="http://en.wikipedia.org/wiki/Principle_of_least_privilege"&gt;principle of the least privilege&lt;/a&gt;. &lt;p&gt;Despite the fact that Microsoft’s products continue topping the “successfully exploited charts” in each and every web malware exploitation kit (&lt;a href="http://blogs.zdnet.com/security/?p=2030"&gt;go through&lt;/a&gt; sample &lt;a href="http://blogs.zdnet.com/security/?p=1598"&gt;infection rates&lt;/a&gt;), long gone are the days when Microsoft’s products are targeted exclusively. Nowadays, in order to better optimize a malware campaign, &lt;a href="http://blogs.zdnet.com/security/?p=2217"&gt;a web malware exploitation kit&lt;/a&gt; is targeting a diverse set of client-side software/browser plugins.&lt;/p&gt; &lt;p&gt;Here are some of the key points from the report :&lt;/p&gt; &lt;p&gt;&lt;span id="more-2517"&gt;&lt;/span&gt;&lt;/p&gt; &lt;ul&gt;&lt;li&gt;92% of Critical Microsoft vulnerabilities are mitigated by configuring users to operate without administrator rights&lt;/li&gt;&lt;li&gt;Of the total published Microsoft vulnerabilities, 69% are mitigated by removing administrator rights&lt;/li&gt;&lt;li&gt;By removing administrator rights companies will be better protected against exploitation of 94% of Microsoft Office, 89% of Internet Explorer, and 53% of Microsoft Windows vulnerabilities&lt;/li&gt;&lt;li&gt;87% of vulnerabilities categorized as Remote Code Execution vulnerabilities are mitigated by removing administrator rights&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;Interestingly, starting from the basic fact that the client-side vulnerabilities exploited through the web exploitation kits have had their associated patches for months, sometimes years, end users appear to not only lack understanding of least privilege accounts, but also, still believe that patching their browser is where &lt;a href="http://secunia.com/vulnerability_scanning/online/"&gt;the self-auditing process&lt;/a&gt; both, starts and ends.&lt;/p&gt; &lt;p&gt;Moreover, the ongoing &lt;a href="http://blogs.zdnet.com/security/?p=2388"&gt;Conficker/Downadup malware campaign&lt;/a&gt; which has already passed the 10 million infected hosts milestone, is a very recent example of another phenomenon - the fact that millions of end users and possibly companies, are on purposely using pirated copies of Windows and are therefore using highly vulnerable, yet Internet connected, versions of it. The proof? &lt;a href="https://forums.symantec.com/t5/blogs/blogarticlepage/blog-id/malicious_code/article-id/228"&gt;Symantec’s geolocated graph of infected Conficker hosts speaks for itself&lt;/a&gt;, as the countries having the &lt;a href="http://global.bsa.org/idcglobalstudy2007/"&gt;highest software piracy rate&lt;/a&gt;, are in fact the ones most heavily hit by the malware.&lt;/p&gt; &lt;p&gt;However, least privilege accounts can always be used by both, legitimate users and software pirates altogether, which when combined with a decent situational awareness in the sense of knowing the current attack tactics, is prone to decrease their chance of getting successfully compromised.&lt;/p&gt;&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;] &lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-6469089161755305470?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/6469089161755305470/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=6469089161755305470' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/6469089161755305470'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/6469089161755305470'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/02/report-92-of-critical-microsoft.html' title='Report: 92% of critical Microsoft vulnerabilities mitigated by Least Privilege accounts'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-1552694260921469899</id><published>2009-02-11T20:53:00.000-08:00</published><updated>2009-02-11T20:59:50.878-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Passwords'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Anti Virus'/><category scheme='http://www.blogger.com/atom/ns#' term='Botnets'/><title type='text'>Fake Antivirus XP pops-up at Cleveland.com</title><content type='html'>&lt;p&gt;&lt;a href="http://i.zdnet.com/blogs/cleveland_fake_antivirus_xp.png"&gt;&lt;img class="size-full wp-image-2514 alignleft" src="http://i.zdnet.com/blogs/cleveland_fake_antivirus_xp.png" alt="" height="103" width="138" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;/p&gt;&lt;p&gt;Have we reached the phrase when targeted advertising would equal evasive malware campaigns pushed through third-party ad networks, to a geolocated set of visitors only?

During the weekend, &lt;a href="http://blog.cleveland.com/metro/2009/02/malware_trips_up_clevelandcom.html"&gt;rogue antivirus XP pop-ups were served to visitors of Cleveland.com&lt;/a&gt;, according to &lt;a href="http://mbd.scout.com/mb.aspx?s=149&amp;amp;f=1547&amp;amp;t=3908794"&gt;visitors’ complaints&lt;/a&gt; which I also managed to verify.&lt;/p&gt; &lt;p&gt;Investigating further reveals that the very same ad network that was used to serve similar &lt;a href="http://dole.allrecipes.com/Recipe-Exchange/Recipe-Request.aspx?requestID=59454"&gt;Antivirus 2009 pop-ups at AllRecipes.com in November&lt;/a&gt;, appears to have been the one (&lt;strong&gt;tacoda.net&lt;/strong&gt;) that cybercriminals once again used in Cleveland.com’s case.&lt;/p&gt; &lt;p&gt;&lt;span id="more-2513"&gt;&lt;/span&gt;&lt;/p&gt; &lt;p&gt;With efficiency-centered ad networks in terms of allowing publishers faster access to their networks, &lt;a href="http://blogs.zdnet.com/security/?p=2405"&gt;every cybercriminal&lt;/a&gt;, no matter the ad network in question, can easily become a publisher - &lt;a href="http://blogs.zdnet.com/security/?p=1815"&gt;the basics of malvertising&lt;/a&gt; whose key advantage from the cybecriminal’s perspective remains the opportunity to target high trafficked web sites which aren’t susceptible to common exploitation tactics.&lt;/p&gt; &lt;p&gt;What ad networks should set as a priority is establishing a more transparent process about what measures — if any — have they undertaken to verify that the publisher’s sites aren’t disseminating &lt;a href="http://sunbeltblog.blogspot.com/2008/08/xp-antivirus-2008-now-with-sploits.html"&gt;malware or client-side exploits&lt;/a&gt;.

Once vulnerabilities are detected by FuzzOr, a programmer can then repair the PL/SQL code.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;Pete Finnigan, who had a look at FuzzOr prior to today’s release, &lt;a href="http://www.petefinnigan.com/weblog/archives/00001227.htm"&gt;explains the nitty-gritty of how it works&lt;/a&gt;:&lt;/p&gt; &lt;ul&gt;&lt;li&gt;It’s written in PL/SQL, tests PL/SQL packages, functions and procedures and is driven by a set of database tables to hold the configuration and the results. The idea is that you can target a particular package or a complete schema.&lt;/li&gt;&lt;li&gt;The nature of a fuzzer is that it sends random input to a particular function or procedure so its running that code hoping to crash it. &lt;strong&gt;Therefore do not run this tool on a production database or any database that you do not want to damage.&lt;/strong&gt;&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;The tool is available as a &lt;a href="https://www.sentrigo.com/register_for_fuzzor.htm"&gt;free download&lt;/a&gt; (registration required).&lt;/p&gt;&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;] &lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-105660294234156757?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/105660294234156757/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=105660294234156757' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/105660294234156757'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/105660294234156757'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/02/fuzzing-for-oracle-database.html' title='Fuzzing for Oracle database vulnerabilities'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-5990631287107546749</id><published>2009-02-05T22:37:00.000-08:00</published><updated>2009-02-05T22:43:17.323-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Patch Watch'/><category scheme='http://www.blogger.com/atom/ns#' term='Exploit Code'/><category scheme='http://www.blogger.com/atom/ns#' term='Data  theft'/><category scheme='http://www.blogger.com/atom/ns#' term='Open Source'/><category scheme='http://www.blogger.com/atom/ns#' term='Arbitrary  Code  Execution'/><category scheme='http://www.blogger.com/atom/ns#' term='Pen testing'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><title type='text'>phpBB.com hacked; Details scarce</title><content type='html'>&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=2493"&gt;&lt;img class="size-full wp-image-2494 alignleft" style="" src="http://i.zdnet.com/blogs/phpbb_logo.jpg" alt="" width="142" height="113" /&gt;&lt;/a&gt;&lt;strong&gt;[ UPDATE: A reader e-mailed a link to &lt;a href="http://hackedphpbb.blogspot.com/"&gt;this blog describing a blow-by-blow attack &lt;/a&gt;against phpBB.com. ]&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;One of the most widely used open-source bulletin board system in the world has been attacked by malicious hackers.&lt;/p&gt; &lt;p&gt;According to a brief “maintenance” notice posted on the &lt;a href="http://www.phpbb.com/"&gt;phpbb.com&lt;/a&gt; home page (screenshot below), the attack occurred through a vulnerability in an outdated PHPList installation.&lt;/p&gt; &lt;p&gt;No other details were offered.

Tackling it will not render the tool’s functionality useless, but will at least ruin the efficiency model. Sadly, &lt;strong&gt;Twitter doesn’t require you to have a valid email address when registering a new account&lt;/strong&gt;, so even though a nonexistent@email.com is used, the user is still registered and is allowed to use Twitter.&lt;/p&gt; &lt;p&gt;&lt;a href="http://i.zdnet.com/blogs/twitter_register_bogus1.png"&gt;&lt;img class="size-full wp-image-2481 alignleft" src="http://i.zdnet.com/blogs/twitter_register_bogus1.png" alt="" width="169" height="105" /&gt;&lt;/a&gt;So starting from the basics of requiring a validation by clicking on a link which will only be possible if a valid email is provided could really make an impact in this case, since it its current form the Twitter registration process can be so massively abused that I’m surprised it hasn’t happened yet. Once a Twitter spammer has been detected, the associated, and now legitimate email could be banned from further registrations, potentially emptying the inventory of bogus emails, and most importantly making it more time consuming for spammers to abuse Twitter in general.&lt;/p&gt; &lt;p&gt;If TweetTornado is indeed the advertising tool of choice for Twitter marketers, I “wonder” why is the originally blurred by the author Twitter account used in the proof (&lt;a href="http://209.85.129.132/search?q=cache%3Atwitter.com%2FAarensAbritta&amp;amp;ie=utf-8&amp;amp;oe=utf-8&amp;amp;aq=t&amp;amp;rls=org.mozilla:en-US:official&amp;amp;client=firefox-a"&gt;&lt;strong&gt;twitter.com/AarensAbritta&lt;/strong&gt;&lt;/a&gt;) currently suspended, the way the rest of the automatically registered ones are?

On a shared system, applications relying upon these HTTP directives could potentially expose private data. Another user on the system could use this vulnerability to view improperly cached pages containing private data by navigating the browser back.&lt;/li&gt;&lt;li&gt;&lt;strong&gt;&lt;a class="low" href="http://www.mozilla.org/security/announce/2009/mfsa2009-05.html"&gt;MFSA 2009-05&lt;/a&gt;:&lt;/strong&gt; Developer and Mozilla community member Wladimir Palant reported that cookies marked HTTPOnly were readable by JavaScript via the XMLHttpRequest.getResponseHeader and APIs. This vulnerability bypasses the security mechanism provided by the HTTPOnly flag which intends to restrict JavaScript access to document.cookie. XMLHttpRequest.getAllResponseHeaders. The fix prevents the XMLHttpRequest feature from accessing the Set-Cookie and Set-Cookie2 headers of any response whether or not the HTTPOnly flag was set for those cookies.&lt;/li&gt;&lt;li&gt;&lt;strong&gt;&lt;a class="moderate" href="http://www.mozilla.org/security/announce/2009/mfsa2009-04.html"&gt;MFSA 2009-04:&lt;/a&gt; &lt;/strong&gt; (Moderate severity)   Mozilla security researcher Georgi Guninski reported that the fix for an earlier vulnerability reported by Liu Die Yu using local internet shortcut files to access other sites (&lt;a href="http://www.mozilla.org/security/announce/2008/mfsa2008-47.html"&gt;MFSA 2008-47&lt;/a&gt;) could be bypassed by redirecting to a privileged about: URI such as &lt;a href="http://blogs.zdnet.com/security/plugins"&gt;about:plugins&lt;/a&gt;. If an attacker could get a victim to download two files, a malicious HTML file and a .desktop shortcut file, they could have the HTML document load a privileged chrome document via the shortcut and both documents would be treated as same origin. This vulnerability could potentially be used by an attacker to inject arbitrary code into the chrome document and execute with chrome privileges. Because this attack has relatively high complexity, the severity of this issue was determined to be moderate.&lt;/li&gt;&lt;li&gt;&lt;strong&gt;&lt;a class="high" href="http://www.mozilla.org/security/announce/2009/mfsa2009-03.html"&gt;MFSA 2009-03&lt;/a&gt;:&lt;/strong&gt; (High severity) Mozilla security researcher moz_bug_r_a4 reported that a form input control’s type could be changed during the restoration of a closed tab. An attacker could set an input control’s text value to the path of a local file whose location was known to the attacker. If the tab was then closed and the victim persuaded to re-open it, upon restoring the tab the attacker could use this vulnerability to change the input type to file. Scripts in the page could then automatically submit the form and steal the contents of the user’s local file.&lt;/li&gt;&lt;li&gt;&lt;strong&gt;&lt;a class="high" href="http://www.mozilla.org/security/announce/2009/mfsa2009-02.html"&gt;MFSA 2009-02&lt;/a&gt;:&lt;/strong&gt; (High severity) Mozilla security researcher moz_bug_r_a4 reported that a chrome XBL method can be used in conjuction with window.eval to execute arbitrary JavaScript within the context of another website, violating the same origin policy. Firefox 2 releases are not affected.

Some of these crashes showed evidence of memory corruption under certain circumstances and we presume that with enough effort at least some of these could be exploited to run arbitrary code.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;The patch is being released automatically via Firefox’s built-in update mechanism.

Adobe is aware of this issue and has helped us develop this mitigation while they work on a fix for all users.&lt;/li&gt;&lt;li&gt;Severity: Moderate. This could allow a PDF document to run scripts on arbitrary sites.&lt;/li&gt;&lt;/ul&gt; &lt;/li&gt;&lt;/ul&gt; &lt;ul&gt;&lt;li&gt;&lt;strong&gt;CVE-2009-0276: Javascript Same-Origin Bypass&lt;/strong&gt; &lt;ul&gt;&lt;li&gt;A bug in the V8 JavaScript engine could allow bypassing same-origin checks in certain situations.&lt;/li&gt;&lt;li&gt;Severity: High. A malicious script in a page could read the full URL of another frame, and possibly other attributes or data from another frame in a different origin. This could disclose sensitive information from one website to a third party.&lt;/li&gt;&lt;/ul&gt; &lt;/li&gt;&lt;/ul&gt; &lt;p&gt;The patch (&lt;a href="http://sites.google.com/a/chromium.org/dev/getting-involved/dev-channel/release-notes"&gt;see release notes&lt;/a&gt;) also fixes problems with Yahoo Mail and Windows Live Hotmail.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;ALSO READ:&lt;/strong&gt;&lt;/p&gt; &lt;ul&gt;&lt;li&gt;&lt;a title="Permanent Link to Google adds HTTPS-only browsing to Chrome" rel="bookmark" href="http://blogs.zdnet.com/security/?p=2369"&gt;Google adds HTTPS-only browsing to Chrome&lt;/a&gt;&lt;/li&gt;&lt;li&gt;&lt;a title="Permanent Link to Google Chrome, the security tidbits" rel="bookmark" href="http://blogs.zdnet.com/security/?p=1837"&gt;Google Chrome, the security tidbits&lt;/a&gt;&lt;/li&gt;&lt;li&gt;&lt;a title="Permanent Link to Google Chrome vulnerable to carpet-bombing flaw" rel="bookmark" href="http://blogs.zdnet.com/security/?p=1843"&gt;Google Chrome vulnerable to carpet-bombing flaw&lt;/a&gt;&lt;/li&gt;&lt;li&gt;&lt;a title="Permanent Link to Google hires browser hacking guru" rel="bookmark" href="http://blogs.zdnet.com/security/?p=410"&gt;Google hires browser hacking guru&lt;/a&gt;&lt;/li&gt;&lt;/ul&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;]&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-1101072172514546675?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/1101072172514546675/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=1101072172514546675' title='1 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/1101072172514546675'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/1101072172514546675'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/02/google-plugs-high-risk-holes-in-chrome.html' title='Google plugs ‘high-risk’ holes in Chrome browser'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>1</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-6753544170521700728</id><published>2009-01-28T20:50:00.000-08:00</published><updated>2009-01-28T20:57:18.674-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Viruses And Worms'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Anti Virus'/><title type='text'>Mac malware will become endemic amongst high-risk groups</title><content type='html'>&lt;p&gt;Two Mac trojan outbreaks were spotted in the past week leaving several people, including myself, to wonder if the tipping point for the Mac malware epidemic has arrived. Frankly, I don’t know, but I tend not to think so. I do think, however, that Mac malware will now become endemic amongst the high-risk groups such as file-swappers.&lt;br /&gt;&lt;span id="more-2430"&gt;&lt;/span&gt;&lt;br /&gt;This past week a &lt;a href="http://blogs.zdnet.com/security/?p=2418"&gt;trojan claiming to be the latest iWork release was spotted on file sharing networks&lt;/a&gt;.  Shortly thereafter, &lt;a href="http://blogs.zdnet.com/gadgetreviews/?p=856"&gt;a similar trojan was sighted that masquerading as a crack for Photoshop CS4&lt;/a&gt;. Both events are making some people question whether or not the Mac’s long tenure as being a malware-free system is coming to a close and to face facts and install AV software.&lt;/p&gt; &lt;p&gt;The short answer is if you are a relatively well-behaved computer user, probably not. Mac malware is not endemic amongst the general population due to these events. The trojans of the past week is not self-propagating beyond the high-risk population, namely file swappers, and is relatively easy to find, analyze, and remediate. This is in stark contrast to PC users who have been hit with the Downadup/Conficker worm, which propagates via three orthogonal vectors and includes one remote exploit, and actively prevents you from visiting websites that contain remediation tools.&lt;/p&gt; &lt;p&gt;I do think the relative halcyon days of malware-free Macs are coming to an end. Anyone who is currently infected by the new malware will remain infected without direct human interaction due to the lack of any automatic mechanism for the identification and removal of malware. That means there is a non-zero population of Mac users who are now compromised and will remain compromised unless they either clean their machine or they buy a new system. Sounds familiar, right?&lt;/p&gt; &lt;p&gt;The question I want answered is whether or not the monetization rate of compromised Macs is sufficient for the malware authors to continue to pursue the platform. If not, these events will be a blip on the radar; otherwise, Mac owners better keep their Time Machine backups up to date.&lt;/p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;]&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-6753544170521700728?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/6753544170521700728/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=6753544170521700728' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/6753544170521700728'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/6753544170521700728'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/01/mac-malware-will-become-endemic-amongst.html' title='Mac malware will become endemic amongst high-risk groups'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-2118006589769000637</id><published>2009-01-28T20:44:00.000-08:00</published><updated>2009-01-28T20:50:14.020-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Passwords'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Anti Virus'/><category scheme='http://www.blogger.com/atom/ns#' term='Google'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Web 2.0'/><title type='text'>Google Video search results poisoned to serve malware</title><content type='html'>&lt;a href="http://blogs.zdnet.com/security/?p=2433#comments"&gt;&lt;span&gt;&lt;/span&gt;&lt;/a&gt;&lt;a href="http://i.zdnet.com/blogs/google_video_search_fake_flash1.jpg"&gt;&lt;img class="size-full wp-image-2434 alignleft" src="http://i.zdnet.com/blogs/google_video_search_fake_flash1.jpg" alt="" width="167" height="79" /&gt;&lt;/a&gt;From the real-time syndication of hot &lt;a href="http://blogs.zdnet.com/security/?p=1995"&gt;Google Trends keywords&lt;/a&gt;, maintaining &lt;a href="http://blogs.zdnet.com/security/?p=2405"&gt;AdWords campaigns&lt;/a&gt;, to the plain simple blackhat search engine optimization tactics, cybercriminals are constantly looking for new ways to acquire traffic by enjoying the clean reputation of each and every Web 2.0 property. From &lt;a href="http://blogs.zdnet.com/security/?p=2358"&gt;LinkedIn&lt;/a&gt;, &lt;a href="http://blogs.zdnet.com/security/?p=2097"&gt;Bebo&lt;/a&gt;, &lt;a href="http://blogs.zdnet.com/security/?p=1852"&gt;Picasa and ImageShack&lt;/a&gt;, to &lt;a href="http://blogs.zdnet.com/security/?p=1640"&gt;Twitter&lt;/a&gt;, everyone’s targeted efficiently using automated account registration tools. &lt;p&gt;During the last couple of days, a single group involved in a countless number of blackhat SEO campaigns across the Web, started massively targeting Google Video with a campaign that has already managed to hijack approximately 400,000 search queries in order to trick users into visiting a bogus and malware serving (&lt;a href="http://www.virustotal.com/analisis/346548a92a122e3dc70fd12bcd316a7e"&gt;W32/AutoTDSS.BNA!worm&lt;/a&gt;) adult web site.&lt;/p&gt; &lt;p&gt;Here’s how the campaign works, and how they’re attempting to cloak it from the eyes of security researchers.&lt;/p&gt; &lt;p&gt;&lt;span id="more-2433"&gt;&lt;/span&gt;&lt;/p&gt; &lt;p&gt;&lt;a href="http://i.zdnet.com/blogs/google_video_search_fake_flash2.jpg"&gt;&lt;img class="size-full wp-image-2435 alignleft" src="http://i.zdnet.com/blogs/google_video_search_fake_flash2.jpg" alt="" width="146" height="84" /&gt;&lt;/a&gt;What’s particularly interesting about this campaign relying entirely on Google Video traffic to flourish, is that instead of sticking to the adult content in their keywords inventory, the cybercriminals have been in fact syndicating legitimate YouTube video titles from a variety of topics. Therefore, the number of legitimate videos used is proportional to the comprehensiveness of the campaign, in this case, over 400,000 search queries, a number that is increasing in real-time since they keep having their bogus content crawled by Google Video.&lt;/p&gt; &lt;p&gt;Moreover, based on the fact that they maintain a portfolio of 21 publisher domains with bogus and non-existent video content currently crawled, a simple tactic that they’re using could entirely hijack a search query at Google Video. How come? By simply duplicating the content on their publisher domains, the top 5 search results for a particular video can be easily served from any of the 21 publisher domains, making it look like different sites have the same content.&lt;/p&gt; &lt;p&gt;The search engine results poisoning works as follows. Upon clicking, a Google Video user coming across to any content from any of their 21 publisher domains, is taken to a single redirection point (&lt;strong&gt;porncowboys .net/continue.php&lt;/strong&gt;), then to the well known adult site template abused by cybercriminals (&lt;strong&gt;xfucked .org/video.php?genre=babes&amp;amp;id=7375&lt;/strong&gt;), where the user is told that “&lt;em&gt;Your Flash Version is too old. Your browser cannot play this file. Click “OK” to download and install update for Flash Video Player&lt;/em&gt;” and the malware is served if he’s tricked into it (&lt;strong&gt;trackgame .net/download/FlashPlayer.v3.181.exe&lt;/strong&gt;).&lt;/p&gt; &lt;p&gt;&lt;a href="http://i.zdnet.com/blogs/google_video_search_fake_flash.jpg"&gt;&lt;img class="size-full wp-image-2436 alignleft" src="http://i.zdnet.com/blogs/google_video_search_fake_flash.jpg" alt="" width="153" height="83" /&gt;&lt;/a&gt;The cybercriminals are also taking advantage of a well known evasive technique - http referer checking or “cloaked maliciousness. For instance, the malware redirection to the fake flash player is only served if the potential victim is coming from Google Video. If a researcher is basically browsing around the content of their sites, the legitimate YouTube videos are legitimately syndicated. Excluding this case, it’s worth pointing out that on the majority of occasions cybercriminals do not fully take advantage of the evasive features available within the traffic management kits they use behind the campaigns, making their campaigns easier for analyzing.&lt;/p&gt; &lt;p&gt;Google’s Security Team has been notified and action is expected to be taken anytime now.&lt;/p&gt;&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;] &lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-2118006589769000637?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/2118006589769000637/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=2118006589769000637' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/2118006589769000637'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/2118006589769000637'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/01/google-video-search-results-poisoned-to.html' title='Google Video search results poisoned to serve malware'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-2653983025214711292</id><published>2009-01-24T00:37:00.000-08:00</published><updated>2009-01-24T00:45:23.739-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Passwords'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Anti Virus'/><category scheme='http://www.blogger.com/atom/ns#' term='Spyware and Adware'/><category scheme='http://www.blogger.com/atom/ns#' term='Hackers'/><category scheme='http://www.blogger.com/atom/ns#' term='Google'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><title type='text'>Malware-infected WinRAR distributed through Google AdWords</title><content type='html'>&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/images/adwords_winrar_fake_download.JPG" title="Fake Download Malware Winrar"&gt;&lt;img src="http://blogs.zdnet.com/security/images/adwords_winrar_fake_download.JPG" alt="Fake Download Malware Winrar" width="139" align="left" height="88" /&gt;&lt;/a&gt;Scammers are at it again - taking advantage of Google sponsored ads for acquiring traffic in order to redirect it to malware-infected copies of legitimate software. &lt;a href="http://www.win-rar.com/"&gt;win.rar GmbH&lt;/a&gt; is warning users of an &lt;a href="http://securitylabs.websense.com/content/Blogs/3264.aspx"&gt;ongoing fraudulent AdWords campaign pushing a malware-infected copy of WinRAR&lt;/a&gt;, the popular archiving application. Starting from the basic fact that, both, legitimate and malicious users can purchase their visibility, &lt;a href="http://www.virustotal.com/analisis/d3b3824647262e00f16b8879a8e6d13f"&gt;the fake WinRAR release&lt;/a&gt; is only the tip of the iceberg.&lt;/p&gt; &lt;p&gt;Let’s take a peek at the campaign impersonating &lt;strong&gt;Download.com&lt;/strong&gt; — impersonation is a form of flattery — and discuss a separate campaign promising to deliver free copies of the free in general, WinRAR and WinZip, managed by a &lt;a href="http://en.wikipedia.org/wiki/Zango"&gt;Zango adware affiliate&lt;/a&gt;.&lt;/p&gt; &lt;p&gt; &lt;a href="http://blogs.zdnet.com/security/images/bogus_winzip_zango2.JPG" title="Zango Winzip Google AdWords"&gt;&lt;img src="http://blogs.zdnet.com/security/images/bogus_winzip_zango2.JPG" alt="Zango Winzip Google AdWords" width="136" align="left" height="78" /&gt;&lt;/a&gt;Upon searching for WinRAR, the bogus ad appears at the top of the search results, with the actual fake &lt;strong&gt;Download.com&lt;/strong&gt; site located at &lt;strong&gt;dreamcentury .cn/winrar.htm&lt;/strong&gt;. Upon execution, the fake WinRAR sets the foundation for the second part of the scam, since the affected users would be periodically redirected to rogue security software sites, urging them to take action and disinfect themselves.&lt;/p&gt; &lt;ul&gt;&lt;li&gt;Go through related attack tactics - &lt;a href="http://blogs.zdnet.com/security/?p=1995"&gt;Cybercriminals syndicating Google Trends keywords to serve malware&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=2129"&gt;Fake WordPress site distributing backdoored release&lt;/a&gt;&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/images/bogus_winzip_zango.JPG" title="Zango Winzip Google AdWords"&gt;&lt;img src="http://blogs.zdnet.com/security/images/bogus_winzip_zango.JPG" alt="Zango Winzip Google AdWords" width="133" align="left" height="104" /&gt;&lt;/a&gt;WinRAR is also impersonated in another currently active &lt;a href="http://www.virustotal.com/analisis/6766f039de09b7ae95cb07ec7af1eaed"&gt;AdWords campaign&lt;/a&gt;, next to &lt;a href="http://www.virustotal.com/analisis/1a1c8816399e6878234f6c3fdd8f0ddc"&gt;WinZip&lt;/a&gt;, with the second campaign operated by Zango affiliate, a well known adware vendor. Zango’s campaign is naturally not delivering any copies of WinRAR or WinZip, instead it’s pushing a copy of their toolbar taking advantage of fraudulent practices.&lt;/p&gt; &lt;p&gt;The participants in Zango’s affiliate network and the rogue security software one, are generating revenues based on the number of installations, with the affiliate model’s high payout rates as the main incentive for the introduction of new tactics.  And whereas Google’s AdWords seems to be part of their ad budget in this particular case, sponsored ads are only part of the (fraudulent) marketing mix, with blackhat search engine optimization tactics remaining the traffic acquisition tactic of choice.&lt;/p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;]&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-2653983025214711292?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/2653983025214711292/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=2653983025214711292' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/2653983025214711292'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/2653983025214711292'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/01/malware-infected-winrar-distributed.html' title='Malware-infected WinRAR distributed through Google AdWords'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-9071474274275108654</id><published>2009-01-24T00:17:00.000-08:00</published><updated>2009-01-24T00:26:22.205-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Vulnerability Research'/><category scheme='http://www.blogger.com/atom/ns#' term='Spam And Phishing'/><category scheme='http://www.blogger.com/atom/ns#' term='Complex Attacks'/><category scheme='http://www.blogger.com/atom/ns#' term='Exploit Code'/><category scheme='http://www.blogger.com/atom/ns#' term='Viruses And Worms'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Anti Virus'/><category scheme='http://www.blogger.com/atom/ns#' term='Arbitrary  Code  Execution'/><category scheme='http://www.blogger.com/atom/ns#' term='Hackers'/><category scheme='http://www.blogger.com/atom/ns#' term='Pen testing'/><category scheme='http://www.blogger.com/atom/ns#' term='Microsoft'/><title type='text'>US-CERT warning: Windows does not disable AutoRun properly</title><content type='html'>&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=2410"&gt;&lt;img src="http://blogs.zdnet.com/security/images/autoplay.png" alt="US-CERT: Windows does not disable AutoRun properly" width="480" height="348" /&gt;&lt;/a&gt;&lt;/p&gt; &lt;p&gt;The U.S. Computer Emergency Readiness Team (US-CERT) has issued a technical cyber-security alert to warn that Microsoft’s guidelines for disabling AutoRun in the Windows operating system “are not fully effective” and argues that this “could be considered a vulnerability.”&lt;/p&gt; &lt;p&gt;The U.S. CERT &lt;a href="http://www.us-cert.gov/cas/techalerts/TA09-020A.html"&gt;warning&lt;/a&gt; comes on the heels of &lt;a href="http://blogs.zdnet.com/security/?p=2388"&gt;live malware/worm attacks&lt;/a&gt; that take advantage of the Windows AutoRun and AutoPlay features to improve propagation.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;[ SEE:  &lt;a href="http://blogs.zdnet.com/security/?p=2235" rel="bookmark" title="Permanent Link to Is there no end to the AutoRun madness?"&gt;Is there no end to the AutoRun madness?&lt;/a&gt; ]&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;Here’s the skinny on Microsoft’s hiccup:&lt;/p&gt; &lt;ul&gt;&lt;li&gt;The &lt;a href="http://support.microsoft.com/kb/155217"&gt;Autorun&lt;/a&gt; and &lt;a href="http://www.microsoft.com/technet/prodtechnol/windows2000serv/reskit/regentry/91525.mspx"&gt;NoDriveTypeAutorun&lt;/a&gt; registry values are both ineffective for fully disabling AutoRun capabilities on Microsoft Windows systems. Setting the Autorun registry value to 0 will not prevent newly connected devices from automatically running code specified in the &lt;a href="http://msdn.microsoft.com/en-us/library/bb776823%28VS.85%29.aspx"&gt;&lt;tt&gt;Autorun.inf&lt;/tt&gt;&lt;/a&gt; file. It will, however, disable Media Change Notification (MCN) messages, which may prevent Windows from detecting when a CD or DVD is changed. According to Microsoft, setting the NoDriveTypeAutorun registry value to &lt;tt&gt;0xFF&lt;/tt&gt; “disables Autoplay on all types of drives.” Even with this value set, Windows may execute arbitrary code when the user clicks the icon for the device in Windows Explorer.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;This means that malware authors can place an &lt;tt&gt;Autorun.inf&lt;/tt&gt; file on a device to automatically execute arbitrary code when the device is connected to a Windows system. Code execution may also take place when the user attempts to browse to the software location with Windows Explorer, US-CERT warned.&lt;/p&gt; &lt;p&gt;The alert includes &lt;a href="http://www.us-cert.gov/cas/techalerts/TA09-020A.html"&gt;instructions&lt;/a&gt; for editing the registry to properly disable AutoRun in Microsoft Windows.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;UPDATE: &lt;/strong&gt;Microsoft sent me an e-mail to point out that its &lt;a href="http://support.microsoft.com/kb/953252"&gt;KB953252&lt;/a&gt; document, published in May 2008, describes how to correct the problem of NoDriveTypeAutoRun registry value enforcement.  This prompted an update on the US-CERT notice:&lt;/p&gt; &lt;blockquote&gt;&lt;p&gt;After the update is installed, Windows will obey the NoDriveTypeAutorun registry value. Note that this fix has been released via Microsoft Update to Windows Vista and Server 2008 systems as part of the &lt;a href="http://www.microsoft.com/technet/security/Bulletin/MS08-038.mspx"&gt;MS08-038&lt;/a&gt; Security Bulletin. Windows 2000, XP, and Server 2003 users must install the update manually. Our testing has shown that installing this update and setting the NoDriveTypeAutoRun registry value to &lt;tt&gt;0xFF&lt;/tt&gt; will disable AutoRun.&lt;/p&gt;&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;] &lt;/p&gt;&lt;/blockquote&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-9071474274275108654?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/9071474274275108654/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=9071474274275108654' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/9071474274275108654'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/9071474274275108654'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/01/us-cert-warning-windows-does-not.html' title='US-CERT warning: Windows does not disable AutoRun properly'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-1046752425819778505</id><published>2009-01-24T00:08:00.000-08:00</published><updated>2009-01-24T00:17:11.723-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Vulnerability Research'/><category scheme='http://www.blogger.com/atom/ns#' term='Patch Watch'/><category scheme='http://www.blogger.com/atom/ns#' term='Exploit Code'/><category scheme='http://www.blogger.com/atom/ns#' term='DDos Attack'/><category scheme='http://www.blogger.com/atom/ns#' term='Viruses And Worms'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Data  theft'/><category scheme='http://www.blogger.com/atom/ns#' term='Arbitrary  Code  Execution'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Apple'/><title type='text'>Apple QuickTime bitten by code execution flaws</title><content type='html'>&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=2413"&gt;&lt;img src="http://blogs.zdnet.com/security/images/quicktime_icon.png" alt="QuickTime bitten by code execution flaws" width="80" align="left" border="0" height="107" hspace="20" /&gt;&lt;/a&gt;Apple today released QuickTime 7.6 to fix at least seven serious security flaws that expose Mac OS X and Windows users to remote code execution attacks.&lt;/p&gt; &lt;p&gt;The latest upgrade, available for Mac OS X v10.4.9 - v10.4.11, Mac OS X v10.5 or later, Windows Vista and Windows XP SP2 and SP3, covers vulnerabilities that could be exploited via malicious URLs or booby-trapped movie or audio files.&lt;/p&gt; &lt;p&gt;Here’s the skinny:&lt;/p&gt; &lt;ul&gt;&lt;li&gt;CVE-2009-0001 — A heap buffer overflow exists in QuickTime’s handling of RTSP URLs.

What has changed since then is the &lt;a href="http://www.techcrunch.com/2009/01/13/mobile-payments-getting-traction-on-social-networks-but-fees-are-sky-high/"&gt;growth of mobile payments&lt;/a&gt;/m-payments and mobile wallets, whose popularity is proportionally empowering potential mobile malware authors with all the &lt;a href="http://www.mercatoradvisorygroup.com/index.php?doc=Emerging_Technologies&amp;amp;action=view_item&amp;amp;id=353&amp;amp;catid=5"&gt;purchasing power an infected device has&lt;/a&gt;.&lt;/p&gt; &lt;p&gt;For the time being, among the main reasons why we still haven’t witnessed an epidemic of mobile malware, is sadly because cybercriminals are making enough profit even without exploiting the fact that there are more people with mobile devices, than people with personal computers around the world.&lt;/p&gt;&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;]&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-4106264257677961213?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/4106264257677961213/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=4106264257677961213' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/4106264257677961213'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/4106264257677961213'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/01/new-mobile-malware-silently-transfers.html' title='New mobile malware silently transfers account credit'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-5354478903817808480</id><published>2009-01-23T23:55:00.000-08:00</published><updated>2009-01-23T23:59:29.689-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Vulnerability Research'/><category scheme='http://www.blogger.com/atom/ns#' term='DDos Attack'/><category scheme='http://www.blogger.com/atom/ns#' term='Viruses And Worms'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Data  theft'/><category scheme='http://www.blogger.com/atom/ns#' term='Anti Virus'/><category scheme='http://www.blogger.com/atom/ns#' term='Spyware and Adware'/><category scheme='http://www.blogger.com/atom/ns#' term='Arbitrary  Code  Execution'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Apple'/><title type='text'>Mac OS X Malware found in pirated Apple iWork 09</title><content type='html'>&lt;p&gt;Researchers at Intego have intercepted a Mac OS X malware threat circulating in pirated copies of Apple’s iWork 09 software.&lt;/p&gt; &lt;p&gt;The malicious file, dubbed OSX.Trojan.iServices.A, was found on BitTorrent trackers and other sites containing links to pirated software.  The booby-trapped version of the iWord 09 productivity suite is complete and functional but the installer contains an additional package called iWorkServices.pkg, Intego said.&lt;/p&gt; &lt;p&gt; &lt;a href="http://blogs.zdnet.com/security/?p=2418"&gt;&lt;img src="http://blogs.zdnet.com/security/images/intego_iworks_09.jpg" alt="Mac OS X Malware found in pirated Apple iWork 09" align="left" border="0" hspace="20" /&gt;&lt;/a&gt;From &lt;a href="http://www.intego.com/news/ism0901.asp"&gt;the advisory&lt;/a&gt;:&lt;/p&gt; &lt;blockquote&gt;&lt;p&gt;When installing iWork 09, the iWorkServices package is installed. The installer for the Trojan horse is launched as soon as a user begins the installation of iWork, following the installer’s request of an administrator password (in older versions of Mac OS X, 10.5.1 or earlier, there will be no password request). This software is installed as a startup item (in /System/Library/StartupItems/iWorkServices, a location reserved normally for Apple startup items), where it has read-write-execute permissions for root. The malicious software connects to a remote server over the Internet; this means that a malicious user will be alerted that this Trojan horse is installed on different Macs, and will have the ability to connect to them and perform various actions remotely. The Trojan horse may also download additional components to an infected Mac.&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;&lt;strong&gt;[ &lt;a href="http://blogs.zdnet.com/security/?p=629" rel="bookmark" title="Porn video lures dropping DNS-changer Trojan"&gt;Mac Attack: Porn video lures dropping DNS-changer Trojan&lt;/a&gt; ]&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;The company said at least 20,000 Mac users have already downloaded the rigged installer.&lt;/p&gt; &lt;blockquote&gt;&lt;p&gt;The risk of infection is serious, and users may face extremely serious consequences if their Macs are accessible to malicious users.&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;Although malware attacks on the Mac operating system have been limited, &lt;a href="http://ryanlrussell.blogspot.com/2006/10/os-x-malware.html"&gt;they do exist&lt;/a&gt;, especially &lt;a href="http://blogs.zdnet.com/security/?p=629"&gt;on the DNS-changing front&lt;/a&gt;.

Last week’s released &lt;a href="http://elcomsoft.com/ewsa.html"&gt;Wireless Security Auditor&lt;/a&gt; is prone to shorter the time it takes for a network administrator to pen-test the strength of the WPA/WPA2-PSK passwords used on the wireless network. Its core functionality of shortening the wireless password recovery time up to a hundred times based on the GPU used, is naturally going to empower unethical wardrivers with the ability to easily guess the no longer considered secure 8 character passwords.&lt;/p&gt; &lt;p&gt; What’s particularly interesting about the &lt;a href="http://www.elcomsoft.com/EWSA/ewsa_s.gif"&gt;Wireless Security Auditor&lt;/a&gt; is that it attempts to accomplish the password recovery in an offline/stealth mode, instead of the noisy direct router brute forcing approach :&lt;/p&gt; &lt;blockquote&gt;&lt;p&gt;“Elcomsoft Wireless Security Auditor works completely in off-line, undetectable by the Wi-Fi network being probed, by analyzing a dump of network communications in order to attempt to retrieve the original WPA/WPA2-PSK passwords in plain text. Elcomsoft Wireless Security Auditor requires a valid log of wireless communications in standard tcpdumptcpdump. The tcpdumptcpdump format is supported by all commercial Wi-Fi sniffers. In order to audit your wireless network, at least one handshake packet must be present in the tcpdump file.”&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;Meanwhile, &lt;a href="http://www.scmagazineuk.com/Elcomsoft-software-means-WiFi-users-should-step-up-security/article/126091/"&gt;pen-testing companies&lt;/a&gt; have once again urged IT managers and end users to go beyond the 8 character password strength myth, and anticipate the risks posed by the increasingly efficient password recovery solutions hitting the market  :&lt;/p&gt; &lt;blockquote&gt;&lt;p&gt;“David Hobson said: “It’s a wake-up call to IT managers, pure and simple. IT managers should now move to 12 and even 16 character keys as a matter of urgency. It’s not very user-friendly, but the potential consequences of staying with eight character keys do not bear thinking about.”&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;As &lt;a href="http://blogs.zdnet.com/security/?p=2033"&gt;previously discussed&lt;/a&gt;, best practices wake-up calls remains largely ignored prompting radical solutions in countries like India for instance, which recently announced that a &lt;a href="http://computing.in.msn.com/articles/article.aspx?cp-documentid=1779184"&gt;Wardriving police unit&lt;/a&gt; will be locating &lt;a href="http://www.business-standard.com/india/news/mumbai-police-plug-wi-fi-security-holes/00/56/346002/"&gt;insecure wireless networks&lt;/a&gt; and notifying the owners in order to “prevent the commission of a cognizable offense”.&lt;/p&gt;&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;]&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-4977782917432130300?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/4977782917432130300/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=4977782917432130300' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/4977782917432130300'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/4977782917432130300'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/01/gpu-accelerated-wi-fi-password-cracking.html' title='GPU-Accelerated Wi-Fi password cracking goes mainstream'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-814871792499446637</id><published>2009-01-18T21:24:00.000-08:00</published><updated>2009-01-18T21:26:20.446-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Passwords'/><category scheme='http://www.blogger.com/atom/ns#' term='Viruses And Worms'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Anti Virus'/><category scheme='http://www.blogger.com/atom/ns#' term='Hackers'/><category scheme='http://www.blogger.com/atom/ns#' term='Botnets'/><title type='text'>Legal concerns stop researchers from disrupting the Storm Worm botnet</title><content type='html'>&lt;span style="display: none;" class="more"&gt;&lt;/span&gt;&lt;a href="http://blogs.zdnet.com/security/images/ccc_2008.JPG" title="Chaos Communications Congress"&gt;&lt;img src="http://blogs.zdnet.com/security/images/ccc_2008.JPG" alt="Chaos Communications Congress" width="210" align="left" height="44" /&gt;&lt;/a&gt;What if security researchers were able to disrupt the leftovers of the Storm Worm botnet thanks to a flaw in its communication model allowing them to redirect infected hosts and eventually disinfect them, but fearing legal action have their hands tied? &lt;p&gt;At the &lt;a href="http://events.ccc.de/congress/2008/"&gt;25th Chaos Communication Congress&lt;/a&gt;, which took place in December, 2008, &lt;a href="http://mwcollect.org/"&gt;German researchers&lt;/a&gt; &lt;strong&gt;Georg Wicherski&lt;/strong&gt;, &lt;strong&gt;Tillmann Werner&lt;/strong&gt;, &lt;strong&gt;Felix Leder&lt;/strong&gt; and &lt;strong&gt;Mark Schlösser&lt;/strong&gt;, held a presentation (&lt;a href="http://events.ccc.de/congress/2008/Fahrplan/events/3000.en.html"&gt;Stormfucker: Owning the Storm Botnet&lt;/a&gt;) demonstration their idea.  The apparently working concept has a single flaw by itself - it operates in exactly the same fashion that a botnet master does when issuing updated malware binaries to the infected hosts, thereby violating computer abuse laws internationally.&lt;/p&gt; &lt;p&gt;Go through a Q&amp;amp;A with the researchers offering insights on the potential for distributed disinfection, and Storm Worm in general.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Q&lt;/strong&gt;: How did you come up with the &lt;a href="http://seclists.org/fulldisclosure/2008/Dec/0588.html"&gt;Stormfucker&lt;/a&gt; idea at the first place, and could you provide us with more details on the lack of server authentication when communicating to the infected clients that the Storm Worm botnet is vulnerable to?&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Georg&lt;/strong&gt;: On the 24c3 congress at the end of 2007, &lt;strong&gt;Thorsten Holz&lt;/strong&gt; gave a presentation on disrupting Zhelatin’s command and control infrastructure, involving a /16 network or 65536 nodes in other terms. This seemed both unfeasible to us and motivated to do better, we started analyzing Zhelatin binaries and eventually found out, that NAT’ed nodes don’t require any authentication to be commanded at all.&lt;/p&gt; &lt;p&gt;They simply use a four-byte XOR challenge response for distinguishing between real command nodes and maybe accidentally connected nodes and that is it, as long as you implement the server protocol properly, you can command these nodes. Later it was brought to our attention that the small minority of non-NAT’ed nodes checks for a 64bit RSA signature, which is obviously trivial to crack.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Q&lt;/strong&gt;: So basically, Stormfucker is capable of issuing potential disinfection commands to infected hosts meaning the botnet can be a thing from the past? What are the legal implications of saving the infected users from themselves here?&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Georg&lt;/strong&gt;: Stormfucker is able to send an update to a storm node that will then download an executable from a Stormfucker provided host and execute it. This executable would then be a Stormfucker executable that disinfects the computer and also aids in propagation of the update commands. Obviously, issuing a command to download and execute a file without the users’ consent is against the law in many countries, let alone the then carried out further propagation of this command to other users.&lt;/p&gt; &lt;ul&gt;&lt;li&gt;Go through previous Storm Worm campaigns - &lt;a href="http://blogs.zdnet.com/security/?p=1131"&gt;The Storm Worm would love to infect you&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=1178"&gt;Tracking down the Storm Worm malware&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=1440"&gt;Storm Worm’s Independence Day campaign&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=1462"&gt;Storm Worm says the U.S have invaded Iran&lt;/a&gt;&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;&lt;strong&gt;Q&lt;/strong&gt;: The industry and the general public has never been comfortable with the idea of “white worms” or “ethical worms”, and perhaps with a reason. Is this distributed disinfection method any different? Moreover, since there’s never been a shortage of pragmatic solutions to a problem that’s the main vehicle driving the cybercrime ecosystem, what would be the best way to put this pragmatic capabilities into action?&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Georg&lt;/strong&gt;: It is exactly like a white worm, the Stormfucker executable spreads from host-to-host in a distributed setup, however only targeting Zhelatin nodes — other nodes will not see any extra traffic. Luckily some law enforcement agencies in some countries see the need to put an end to such menaces as Zhelatin and other botnets, maybe some of these people will push the button with proper legislation in the future. Rumor has it that it has happened in isolated cases before.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Q:&lt;/strong&gt; What are your thoughts of a potential (free) opt-in service, where for instance, end users can request to be at least notified that they are part of Storm Worm’s botnet or any other botnet in particular?&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Georg:&lt;/strong&gt; People who are so ignorant to execute an email attachment from an untrusted source would never sign up for such a service. A much better solution is taken by a local German ISP, NetCologne: they are allowed by their AUP to cut off users that are identified to be infected with malware and they have a Nepenthes based system to find such users. Being cut off from the Internet makes these ignorant people clean their computers pretty fast, so that they can browse the tubes again. Other ISPs should come up with similar solutions!&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Q:&lt;/strong&gt; Storm Worm’s copycat Waledac (the same malware gang behind Storm) is currently spreading in the wild, would the same tactic work against it for instance, and how is Waledac’s communication model any different than Storm Worm’s original one?&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Tillmann Werner&lt;/strong&gt;: From the code perspective, waledac isn’t storm’s copycat, it’s totally different, besides the fact that it also uses a p2p infrastructure. For instance, it communicates via encrypted XML messages over HTTP, thus it’s immune to the sibyl attack. It does provide fast-flux DNS services similar to storm, but we would expect that from every serious malware these days, right? Some people think that there is the same group behind storm and waledac. Maybe, maybe not - who wants to know?&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Felix Leder&lt;/strong&gt;: Waledac is pretty new and the C&amp;amp;C structure not researched in-depth, yet. We are on it and may find something interesting. Currently we can only say that it is using “state-of-the-art” cryptography, which complicates things a bit but doesn’t make it invulnerable. Instead of P2P, Waledac uses Fast-Flux networks. It is definitely possible to place controlled nodes in those networks. Whether those nodes can issue commands has to be investigated. So in short: The same tactics may work, but some more research has to be done.&lt;/p&gt; &lt;p&gt;The inside of Waledac is a lot different from Storm and similarities are hardly there. It is definitely a complete rewrite. The similarities (we have seen so far) are the use of open-source libraries in the malware, nodes that speak both storm and Waledac, and decentralized communication.&lt;/p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-814871792499446637?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/814871792499446637/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=814871792499446637' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/814871792499446637'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/814871792499446637'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/01/legal-concerns-stop-researchers-from.html' title='Legal concerns stop researchers from disrupting the Storm Worm botnet'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-3898825424623716515</id><published>2009-01-18T21:20:00.000-08:00</published><updated>2009-01-18T21:24:03.560-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='DDos Attack'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Hackers'/><category scheme='http://www.blogger.com/atom/ns#' term='Pen testing'/><category scheme='http://www.blogger.com/atom/ns#' term='Botnets'/><title type='text'>GoDaddy hit by a DDoS attack</title><content type='html'>&lt;a href="http://blogs.zdnet.com/security/?p=2391#comments"&gt;&lt;span&gt;&lt;/span&gt;&lt;/a&gt;&lt;a href="http://blogs.zdnet.com/security/images/godaddy-logo.jpg" title="Go Daddy"&gt;&lt;img src="http://blogs.zdnet.com/security/images/godaddy-logo.jpg" alt="Go Daddy" width="104" align="left" height="94" /&gt;&lt;/a&gt;Domain name registrar and web hosting provider &lt;strong&gt;GoDaddy.com&lt;/strong&gt;, was &lt;a href="http://news.cnet.com/8301-17939_109-10143010-2.html?tag=newsEditorsPicksArea.0"&gt;hit by a DDoS attack on Wednesday&lt;/a&gt; affecting thousands of its shared hosting customers for several hours.

The attack technique is somewhat sophisticated — it requires that a base Web site is compromised and the attacker must know which Web site the victim user is currently logged into — in-session phishing can be highly effective because the average end user is likely to enter credentials without a second thought.&lt;/p&gt; &lt;p&gt;Here’s how it works:&lt;/p&gt;  &lt;ol&gt;&lt;li&gt;A user logs onto their online banking application. Leaving this browser window open, the user then navigates to other Web sites.&lt;/li&gt;&lt;li&gt;A short time later a pop-up box appears, allegedly from the banking website, requesting the user re-type their username and password because the session has expired, or complete a customer satisfaction survey, or participate in a promotion, etc.&lt;/li&gt;&lt;li&gt;Since the user had recently logged onto the banking website, he/she will likely not suspect this pop-up is fraudulent and thus provide the requested details.&lt;/li&gt;&lt;/ol&gt; &lt;p&gt;To mount a successful in-session phishing attack, a base Web site must be compromised (&lt;a href="http://news.zdnet.co.uk/security/0,1000000189,39429909,00.htm"&gt;check!&lt;/a&gt;), the malware injected onto the hijacked Web site must be able to identify the site the user is logged into (not trivial but &lt;a href="http://ha.ckers.org/blog/20061108/detecting-states-of-%20%20authentication-with-protected-images/"&gt;very possible&lt;/a&gt;).&lt;/p&gt; &lt;p&gt;Trusteer has issued a &lt;a href="http://www.trusteer.com/files/In-session-phishing-advisory-2.pdf"&gt;research paper&lt;/a&gt; (.pdf) that calls attention to a vulnerability in the JavaScript engine of all leading browsers — Internet Explorer, Firefox, Safari, and Chrome — which  allows a Web site to check whether a user is currently logged onto another website.&lt;/p&gt; &lt;blockquote&gt;&lt;p&gt;The source of the vulnerability is a specific JavaScript function. When this function is called it leaves a temporary footprint on the computer and any other website can identify this footprint. Websites that use this function in a certain way are traceable. Many websites, including financial institutions, online retailers, social networking websites, gaming, and gambling websites use this function and can be traced.&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;It explains how a skilled attacker can program a compromised website needs to maintain a list of sites it wants to check.&lt;/p&gt; &lt;blockquote&gt;&lt;p&gt;There is no limit to the number of URLs that a compromised website can check for logged on users. It simply asks the browser a simple question: “is the user currently logged onto this specific website?” and the browser will answer “yes” or “no”. Once the compromised website identifies a website to which the user is logged on, it can inject a pop up message in the browser pretending to be from the legitimate website and asking for credentials and private information.&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;To protect themselves from in-session phishing attacks, Trusteer recommends that users:&lt;/p&gt; &lt;ol&gt;&lt;li&gt;Deploy Web browser security tools.&lt;/li&gt;&lt;li&gt;Always log out of banking and other sensitive online applications and accounts before navigating to other websites.&lt;/li&gt;&lt;li&gt;Be extremely suspicious of pop ups that appear in a web session if you have not clicked a hyperlink.&lt;/li&gt;&lt;/ol&gt; &lt;p&gt;&lt;em&gt;* Image source: &lt;a href="http://www.flickr.com/photos/toasty/1276202472/"&gt;ToastyKen’s Flickr photostream&lt;/a&gt; (Creative Commons 2.0)&lt;br /&gt;&lt;/em&gt;&lt;/p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;]&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-4886521228384752235?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/4886521228384752235/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=4886521228384752235' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/4886521228384752235'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/4886521228384752235'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/01/phishing-without-bait-in-session.html' title='Phishing without bait: The in-session password theft attack'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-5414279900790739661</id><published>2009-01-18T21:07:00.000-08:00</published><updated>2009-01-18T21:10:38.283-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Exploit Code'/><category scheme='http://www.blogger.com/atom/ns#' term='Viruses And Worms'/><category scheme='http://www.blogger.com/atom/ns#' term='Hackers'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Botnets'/><title type='text'>3.5m hosts affected by the Conficker worm globally</title><content type='html'>&lt;a href="http://blogs.zdnet.com/security/?p=2388#comments"&gt;&lt;span&gt;&lt;/span&gt;&lt;/a&gt;                &lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/images/port_445_sans.JPG" title="Conficker 445 Port SANS"&gt;&lt;img src="http://blogs.zdnet.com/security/images/port_445_sans.JPG" alt="Conficker 445 Port SANS" width="156" align="left" height="111" /&gt;&lt;/a&gt;A recently conducted experiment by F-Secure estimates that &lt;a href="http://www.f-secure.com/weblog/archives/00001580.html"&gt;approximately 3.5 million hosts have been infected&lt;/a&gt; with &lt;a href="http://blogs.zdnet.com/security/?p=2228"&gt;W32/Conficker.worm&lt;/a&gt; also known as &lt;a href="http://blogs.zdnet.com/security/?p=2296"&gt;W32.Downadup&lt;/a&gt; spreading through the now patched &lt;a href="http://www.microsoft.com/technet/security/Bulletin/MS08-067.mspx"&gt;MS08-067&lt;/a&gt; as of &lt;a href="http://isc.sans.org/port.html?port=445"&gt;November, 2008&lt;/a&gt;. Basically, &lt;a href="http://www.f-secure.com/weblog/archives/00001579.html"&gt;F-Secure’s experiment&lt;/a&gt; took advantage of the very same &lt;a href="http://www.f-secure.com/weblog/archives/downadup_domain_blocklist.txt"&gt;domain registration algorithm&lt;/a&gt; that the cybercriminals were using in order to temporarily redirect some of the infected hosts and in the meantime count the number of infected hosts.&lt;/p&gt; &lt;p&gt;With several &lt;a href="http://blogs.technet.com/mmpc/archive/2009/01/13/msrt-released-today-addressing-conficker-and-banload.aspx"&gt;new Conficker variants&lt;/a&gt; released since the &lt;a href="http://blogs.zdnet.com/security/?p=2328"&gt;original November campaign&lt;/a&gt;, the worm’s authors seem to be diversifying the propagation vectors in order to &lt;a href="https://forums.symantec.com/t5/blogs/blogarticlepage/blog-id/malicious_code/article-id/224"&gt;increase the worm’s lifecycle&lt;/a&gt;.&lt;/p&gt; &lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/images/conficker_affiliate_fake_security_software.jpg" title="Conficker Affiliate Network"&gt;&lt;img src="http://blogs.zdnet.com/security/images/conficker_affiliate_fake_security_software.jpg" alt="Conficker Affiliate Network" width="140" align="left" height="109" /&gt;&lt;/a&gt;The latest propagation tactics include USB spreading, network shares spreading, and according to McAfee, the latest samples that they’ve analyzed are &lt;a href="http://www.avertlabs.com/research/blog/index.php/2009/01/15/conficker-worm-using-metasploit-payload-to-spread/"&gt;attempting to exploit only English language OS versions&lt;/a&gt; thanks to an OS fingerprinting feature within a Metasploit exploit used by the worm’s authors.&lt;/p&gt; &lt;p&gt;Ever since the first release of the worm, the authors’ criminal intentions became pretty evident. Infected hosts would be exposed to fake security software claiming that the host’s security has been compromised — appreciate the irony here — with the worm’s authors earning $30 for each and every successful sale of the bogus security software. This approach of monetizing malware infected hosts through an affiliate-based network is one of the main incentives for assembling a botnet these days.&lt;/p&gt;&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;] &lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-5414279900790739661?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/5414279900790739661/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=5414279900790739661' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/5414279900790739661'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/5414279900790739661'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/01/35m-hosts-affected-by-conficker-worm.html' title='3.5m hosts affected by the Conficker worm globally'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-5123421121188411808</id><published>2009-01-18T21:05:00.000-08:00</published><updated>2009-01-18T21:07:25.724-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Passwords'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Anti Virus'/><category scheme='http://www.blogger.com/atom/ns#' term='Hackers'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Microsoft'/><category scheme='http://www.blogger.com/atom/ns#' term='Botnets'/><title type='text'>Malware author greets Microsoft’s Windows Defender team</title><content type='html'>&lt;a href="http://blogs.zdnet.com/security/?p=2385#comments"&gt;&lt;span&gt;&lt;/span&gt;&lt;/a&gt;&lt;a href="http://blogs.zdnet.com/security/images/malware_search_fake_codec1.jpg" title="Zlob malware family"&gt;&lt;img src="http://blogs.zdnet.com/security/images/malware_search_fake_codec1.jpg" alt="Zlob malware family" width="145" align="left" height="110" /&gt;&lt;/a&gt;A Russian malware author with involvement in the &lt;a href="http://www.jahewi.nl/lists/fakecodecs/fakecodecs.html"&gt;Zlob malware family&lt;/a&gt;, one of the most prolific malware families in 2008 thanks to its successful mimicking of video codecs, has left a message for the Windows Defender team inside &lt;a href="http://mad.internetpol.fr/archives/8-Zlob-Best-Wishes-With-A-Hidden-Message.html"&gt;a sample analyzed by French researchers&lt;/a&gt;. The message is a follow-up to a &lt;a href="http://blogs.technet.com/mmpc/archive/2008/10/10/malware-writer-wants-an-eye-to-eye-with-us.aspx"&gt;previous note left in October&lt;/a&gt;, and is basically greeting Microsoft in respect to their improving detection rates for this malware family.  &lt;blockquote&gt;&lt;p&gt;For Windows Defender’s Team:&lt;br /&gt;I saw your post in the blog (10-Oct-2008) about my previous message. Just want to say ‘Hello’ from Russia. You are really good guys. It was a surprise for me that Microsoft can respond on threats so fast. I can’t sign here now (he-he, sorry), how it was some years ago for more seriously vulnerability for all Windows ;) Happy New Year, guys, and good luck! P.S. BTW, we are closing soon. Not because of your work. :-)) So, you will not see some of my great ;) ideas in that family of software. Try to search in exploits/shellcodes and rootkits. Also, it is funny (probably for you), but Microsoft offered me a job to help improve some of Vista’s protection. It’s not interesting for me, just a life’s irony.&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;Who’s this guy? The malware author claims that has coded a critical vulnerability affecting Windows a couple of years ago, and that Microsoft has once offered him a job presumably as a researcher. This message clearly indicates the ongoing multitasking mode of cybercriminals. Moreover, even though the author is trying to distance himself from future Zlob releases, the malware family is not going away anytime soon despite that his campaigns have been somehow affected by Microsoft and, of course, the community as a whole.&lt;/p&gt; &lt;p&gt;The reason for that is the affiliation-based model (&lt;a href="http://blogs.zdnet.com/security/?p=2054"&gt;Inside an affiliate spam program for pharmaceuticals&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=1200"&gt;Botnets committing click fraud observed&lt;/a&gt;) cybercriminals have been developing throughout the entire 2008, forwarding the process of dissemination and coming up with lower detection rates to the binaries to third-parties who earn money in the process as long as the infected hosts phone back to desired location. This affiliation-based model is the main factor for the growth of the Zlob malware, now an inseparable part of the underground ecosystem as one of the key promotional tools for fake security software.&lt;/p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;]&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-5123421121188411808?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/5123421121188411808/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=5123421121188411808' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/5123421121188411808'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/5123421121188411808'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/01/malware-author-greets-microsofts.html' title='Malware author greets Microsoft’s Windows Defender team'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-3757425175322832152</id><published>2009-01-18T21:01:00.000-08:00</published><updated>2009-01-18T21:05:00.781-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Vulnerability Scanner'/><category scheme='http://www.blogger.com/atom/ns#' term='Patch Watch'/><category scheme='http://www.blogger.com/atom/ns#' term='Complex Attacks'/><category scheme='http://www.blogger.com/atom/ns#' term='Exploit Code'/><category scheme='http://www.blogger.com/atom/ns#' term='DDos Attack'/><category scheme='http://www.blogger.com/atom/ns#' term='Data  theft'/><category scheme='http://www.blogger.com/atom/ns#' term='Arbitrary  Code  Execution'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><title type='text'>RIM warns of BlackBerry PDF processing vulnerabilities</title><content type='html'>&lt;span style="display: none;" class="more"&gt;&lt;a href="http://updates.zdnet.com/tags/Ryan+Naraine.html"&gt;Ryan Naraine&lt;/a&gt;&lt;/span&gt;     &lt;script&gt;     var tb1 = new CNET.Blog.Toolbar.Interact();     CNET.Blog.Toolbar.Interact.allToolbars.push(tb1);     tb1.id = 'zdsecurity_2378';     CNET.Blog.Toolbar.Interact.service.contentId.push(tb1.id);     tb1.idContainer = 'interact_'+tb1.id;     tb1.title = 'RIM warns of BlackBerry PDF processing vulnerabilities';     tb1.emailTitle = 'RIM warns of BlackBerry PDF processing vulnerabilities | Zero Day | ZDNet.com';     tb1.diggTopic = 'tech_news';     tb1.diggBodyText = 'A ZDNET Blog';     tb1.absoluteUrl = 'http://blogs.zdnet.com/security/?p=2378';     tb1.relativeUrl = '?p=2378';     tb1.commentUrl = '?p=2378#comments';     tb1.blogThisUrl = 'index.php?blogthis=1&amp;p=2378';     tb1.noTalkback = '';     tb1.numTalkbacks = '';     tb1.votingId = tb1.id;     tb1.voteCount = 18;     tb1.voteTotal = 18;      tb1.recommend.hasVoted = false;     tb1.recommend.contentId = 'zdsecurity_2378';     tb1.recommend.userId = '';     tb1.recommend.encodedTitle = 'UklNIHdhcm5zIG9mIEJsYWNrQmVycnkgUERGIHByb2Nlc3NpbmcgdnVsbmVyYWJpbGl0aWVz';     tb1.recommend.encodedUrl = 'aHR0cDovL2Jsb2dzLnpkbmV0LmNvbS9zZWN1cml0eS8_cD0yMzc4';     tb1.recommend.rpcHost = 'blogs.zdnet.com';     tb1.recommend.loginUrl = 'http://www.zdnet.com/1320-4_24-44.html?path=';     tb1.recommend.returnUrl = 'http://blogs.zdnet.com/security/?p=2378';     tb1.recommend.cookieResults = '';     tb1.init(); &lt;/script&gt;                 &lt;p&gt; &lt;a href="http://blogs.zdnet.com/security/?p=2378"&gt;&lt;img src="http://blogs.zdnet.com/security/images/blackberry_curve.jpg" alt="BlackBerry security advisories" width="155" align="left" border="0" height="117" hspace="19" /&gt;&lt;/a&gt; Hackers can use booby-trapped PDF attachments sent to BlackBerry devices to launch malicious code execution attacks, according to warnings issued by Research in Motion (RIM).&lt;/p&gt; &lt;p&gt;The company shipped patches this week to address a pair of critical vulnerabilities affecting its enterprise product line.&lt;/p&gt; &lt;p&gt;The vulnerabilities are due to the improper processing of PDF files within the Distiller component of the BlackBerry Attachment Service, RIM said.  Here are the raw details:&lt;/p&gt;  &lt;ul&gt;&lt;li&gt; &lt;a href="http://www.blackberry.com/btsc/search.do?cmd=displayKC&amp;amp;docType=kc&amp;amp;externalId=KB17118"&gt;KB17118&lt;/a&gt;: Multiple security vulnerabilities exist in the PDF distiller of some released versions of the BlackBerry Attachment Service. These vulnerabilities could enable a malicious individual to send an email message containing a specially crafted PDF file, which when opened for viewing on a BlackBerry smartphone, could cause memory corruption and possibly lead to arbitrary code execution on the computer that hosts the BlackBerry Attachment Service.  These vulnerabilities each have a Common Vulnerability Scoring System (CVSS) score of 9.3.&lt;/li&gt;&lt;li&gt;&lt;a href="http://www.blackberry.com/btsc/search.do?cmd=displayKC&amp;amp;docType=kc&amp;amp;externalId=KB17119"&gt;KB17119&lt;/a&gt;: Multiple security vulnerabilities exist in the PDF distiller of some released versions of the BlackBerry Attachment Service.

Upon closer analysis, it appears that the site has been infected on the 8th of January, Thursday, becoming the very latest legitimate site whose use of outdated web application software led to its exploitation. &lt;p&gt;Moreover, just like we’ve seen in previous related attacks, Hilton’s site compromise is a part of  bigger malware campaign affecting several thousand sites, and is not being exclusively targeted.&lt;/p&gt; &lt;p&gt; &lt;a href="http://blogs.zdnet.com/security/images/paris_hilton_embedded_malware_2.JPG" title="Paris Hilton site infected with malware"&gt;&lt;img src="http://blogs.zdnet.com/security/images/paris_hilton_embedded_malware_2.JPG" alt="Paris Hilton site infected with malware" width="208" align="left" height="24" /&gt;&lt;/a&gt;A javascript embedded at the bottom of the site, is actually an iFrame that used to point to the now down &lt;strong&gt;you69tube .com/flvideo/.a/.t/index .php&lt;/strong&gt;. Once the downloader is executed it attempts to download another binary from the same site, including configuration files from several other sites among which is &lt;strong&gt;ManggaTv.com&lt;/strong&gt;. The abuse and use of legitimate infrastructure as a foundation for the entire malicious campaign, is a common practice applied by cybercriminals these days. For instance, in this campaign not only is the official web site of a popular celebrity used to acquire the traffic, but also, another legitimate site is used as a dropzone for the configuration file of the banker malware.&lt;/p&gt; &lt;ul&gt;&lt;li&gt;Go through related incidents -  &lt;a href="http://blogs.zdnet.com/security/?p=2039"&gt;Adobe’s Serious Magic site SQL Injected by Asprox botnet&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=1339"&gt;200,000 sites spreading web malware, China’s hosting the most&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=1394"&gt;Sony PlayStation’s site SQL injected, redirecting to rogue security software&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=1118"&gt;Redmond Magazine Successfully SQL Injected by Chinese Hacktivists&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=1150"&gt;Over 1.5 million pages affected by the recent SQL injection attacks&lt;/a&gt;.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;Let’s discuss the attackers’ logic applied here. &lt;a href="http://blogs.zdnet.com/security/?p=2328"&gt;December’s massive SQL injection&lt;/a&gt; attack affecting thousands of Chinese web sites used as infection vectors serving the IE XML parsing zero day, is an example of the “long tail of SQL injected sites” versus targeted attacks against high profile sites. Basically, their mentality relies on the fact that not only would thousands of sites acquire more traffic than a high profile one, but also, that their campaign may live longer if they diversify instead of centralizing it by using a single high profile site despite the anticipated traffic that would come from it.&lt;/p&gt; &lt;p&gt;For the time being the malicious iFrame has been removed, and the malware campaign is in a cover-up phrase — they wish.&lt;/p&gt;&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;] &lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-3731166231235399394?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/3731166231235399394/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=3731166231235399394' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/3731166231235399394'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/3731166231235399394'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/01/paris-hiltons-official-web-site-serving.html' title='Paris Hilton’s official web site serving malware'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-3615901550625518813</id><published>2009-01-14T05:29:00.000-08:00</published><updated>2009-01-14T05:33:31.563-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Windows Vista'/><category scheme='http://www.blogger.com/atom/ns#' term='Exploit Code'/><category scheme='http://www.blogger.com/atom/ns#' term='Viruses And Worms'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Pen testing'/><category scheme='http://www.blogger.com/atom/ns#' term='Microsoft'/><category scheme='http://www.blogger.com/atom/ns#' term='Passwords'/><category scheme='http://www.blogger.com/atom/ns#' term='Zero-Day  Attacks'/><category scheme='http://www.blogger.com/atom/ns#' term='Complex Attacks'/><category scheme='http://www.blogger.com/atom/ns#' term='Patch Watch'/><category scheme='http://www.blogger.com/atom/ns#' term='DDos Attack'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Anti Virus'/><category scheme='http://www.blogger.com/atom/ns#' term='Arbitrary  Code  Execution'/><title type='text'>MS Patch Tuesday: 3 critical SMB vulnerabilities</title><content type='html'>&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=2372"&gt;&lt;img src="http://blogs.zdnet.com/security/images/ms_security_shield.JPG" alt="3 critical SMB vulnerabilities" align="left" border="0" hspace="10" /&gt;&lt;/a&gt;Microsoft today shipped a solitary bulletin with patches for at least three documented security flaws in the Microsoft Server Message Block (SMB) Protocol.&lt;/p&gt; &lt;p&gt;The three vulnerabilities, rated “critical” on Windows 2000, Windows XP and Windows Server 2003, exposes Windows users to remote code execution attacks, Microsoft said in its &lt;a href="http://www.microsoft.com/technet/security/Bulletin/MS09-001.mspx"&gt;MS09-001&lt;/a&gt; bulletin.  The company warns:&lt;/p&gt; &lt;blockquote&gt;&lt;p&gt;“An attacker who successfully exploited these vulnerabilities could install programs; view, change, or delete data; or create new accounts with full user rights.”&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;Only two of the three vulnerabilities affect Windows Vista and Windows Server 2008.&lt;/p&gt; &lt;p&gt;Although the exposure to risk seems severe (remote code execution), Microsoft believes it’s &lt;em&gt;unlikely&lt;/em&gt; that functioning exploit code will be created and released.  Microsoft’s &lt;a href="http://blogs.technet.com/swi/archive/2009/01/09/ms09-001-prioritizing-the-deployment-of-the-smb-bulletin.aspx"&gt;Mark Wodrich explains why&lt;/a&gt;:&lt;/p&gt; &lt;ul&gt;&lt;li&gt;The vulnerabilities cause a fixed value (zero) to be written to kernel memory – not data that the attacker controls.&lt;/li&gt;&lt;li&gt;Controlling what data is overwritten is difficult. To exploit this type of kernel buffer overrun, an attacker typically needs to be able to predict the layout and contents of memory. The memory layout of the targeted machine will depend on various factors such as the physical characteristics (RAM, CPUs) of the system, system load, other SMB requests it is processing, etc.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;Eric Schultze, CTO at patch management specialists Shavlik, still recommends that Windows users view at MS09-001 as “super critical to install right away.”&lt;/p&gt; &lt;blockquote&gt;&lt;p&gt;This flaw enables an attacker to send evil packets to a Microsoft computer and take any action they desire on that computer - no credentials required.  The only pre-requisite for this attack to be successful is a connection from the attacker to the victim over the NetBIOS (File and Printer Sharing) ports (tcp 139 or 445).  By default, most computers have these ports turned on.&lt;/p&gt; &lt;p&gt;While these ports are usually blocked on Internet firewalls and personal firewalls, these ports are typically left open in a corporate network.  If a worm is released, and that worm makes it into a corporate network, it will make swiss cheese of that network relatively quickly.&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;According to Roel Schouwenberg, a senior anti-virus researcher at Kaspersky Lab (&lt;a href="http://blogs.zdnet.com/security/?page_id=324"&gt;my employer&lt;/a&gt;) the risk of a network worm attack is minimal.  “It’s unlikely we’ll see a worm,” he said.&lt;/p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;]&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-3615901550625518813?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/3615901550625518813/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=3615901550625518813' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/3615901550625518813'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/3615901550625518813'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/01/ms-patch-tuesday-3-critical-smb.html' title='MS Patch Tuesday: 3 critical SMB vulnerabilities'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-9172411981623279756</id><published>2009-01-14T05:26:00.000-08:00</published><updated>2009-01-14T05:29:02.878-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Vulnerability Research'/><category scheme='http://www.blogger.com/atom/ns#' term='Zero-Day  Attacks'/><category scheme='http://www.blogger.com/atom/ns#' term='Data  theft'/><category scheme='http://www.blogger.com/atom/ns#' term='Arbitrary  Code  Execution'/><category scheme='http://www.blogger.com/atom/ns#' term='Hackers'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Apple'/><category scheme='http://www.blogger.com/atom/ns#' term='Phlashing Attacks'/><title type='text'>Privacy flaw haunts Apple Safari RSS reader</title><content type='html'>&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=2377"&gt;&lt;img src="http://blogs.zdnet.com/security/images/safari_rss.png" alt="Privacy flaw haunts Apple Safari RSS reader" align="left" border="0" hspace="18" /&gt;&lt;/a&gt;There’s a major privacy problem with the RSS reader built into Apple’s Safari browser.&lt;/p&gt; &lt;p&gt;According to an alert from Brian Mastenbrook, there is a serious Safari vulnerability that allows a malicious web site to read files on a user’s hard drive without user intervention.&lt;/p&gt; &lt;p&gt;Mastenbrook warns:&lt;/p&gt;  &lt;blockquote&gt;&lt;p&gt;This can be used to &lt;a href="http://brian.mastenbrook.net/display/27"&gt;gain access to sensitive information&lt;/a&gt; stored on the user’s computer, such as emails, passwords, or cookies that could be used to gain access to the user’s accounts on some web sites.

None of these vulnerabilities may be remotely exploitable without authentication, i.e. may be exploited over a network without the need for a username and password.  2 of these fixes are applicable to client-only installations, i.e. installations that do not have an Oracle Database installed.&lt;/li&gt;&lt;li&gt; 9 new security fixes for the Oracle Secure Backup product.  All of these vulnerabilities may be remotely exploitable without authentication, i.e. may be exploited over a network without the need for a username and password.&lt;/li&gt;&lt;li&gt; 1 new security fix for the Oracle TimesTen Data Server.  This vulnerability is remotely exploitable without authentication, i.e. may be exploited over a network without the need for a username and password.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;According to &lt;a href="http://blog.red-database-security.com/2009/01/13/oracle-critical-patch-update-january-2009-is-out/"&gt;Alexander Kornbrust from Red Database Security&lt;/a&gt;, the most critical bug could allow any user with execute privileges on dbms_ijob (e.g. DBA or hacker/user with DBA privs) to bypass Oracle Auditing completely.&lt;/p&gt; &lt;p&gt;This means no traces in the AUD$ and/or the operating system! All databases are affected.&lt;/p&gt; &lt;p&gt;Risk matrix definitions, including CVSS scores for all the vulnerabilities, are included in &lt;a href="http://www.oracle.com/technology/deploy/security/critical-patch-updates/cpujan2009.html"&gt;Oracle’s advisory&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Technical details on this issue will not be publicly available until Microsoft ships the patch on January 13, 2009.&lt;/p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;]&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-1323417169702976839?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/1323417169702976839/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=1323417169702976839' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/1323417169702976839'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/1323417169702976839'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/01/microsoft-planning-quiet-patch-tuesday.html' title='Microsoft planning quiet Patch Tuesday (1 critical)'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-3011057654436907057</id><published>2009-01-08T21:31:00.000-08:00</published><updated>2009-01-08T21:32:57.876-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Passwords'/><category scheme='http://www.blogger.com/atom/ns#' term='Spam And Phishing'/><category scheme='http://www.blogger.com/atom/ns#' term='Hackers'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Microsoft'/><category scheme='http://www.blogger.com/atom/ns#' term='Botnets'/><category scheme='http://www.blogger.com/atom/ns#' term='Phlashing Attacks'/><title type='text'>Microsoft study debunks phishing profitability</title><content type='html'>&lt;a href="http://blogs.zdnet.com/security/?p=2366#comments"&gt;&lt;span&gt;&lt;/span&gt;&lt;/a&gt;&lt;a href="http://blogs.zdnet.com/security/images/phishing_pages_2008.gif" title="Phishing Pages"&gt;&lt;img src="http://blogs.zdnet.com/security/images/phishing_pages_2008.gif" alt="Phishing Pages" align="left" height="95" width="174" /&gt;&lt;/a&gt;Do phishers actually make money, or is phishing an unprofitable business, scammers lose time and resources into? Taking the economic approach of generalizing how much money phishers make, a recently released study by Microsoft researchers Cormac Herley and Dinei Florencio (&lt;a href="http://research.microsoft.com/en-us/um/people/cormac/Papers/PhishingAsTragedy.pdf"&gt;A Profitless Endeavor: Phishing as Tragedy of the Commons&lt;/a&gt;), states that phishing isn’t as profitable as originally thought. &lt;p&gt;Citing a 1968 published article “&lt;a href="http://en.wikipedia.org/wiki/Tragedy_of_the_commons"&gt;Tragedy of the Commons&lt;/a&gt;” the researchers argue that due to the fact that so many phishers operate on the same scam-scene, they earn less than the could possibly do. Moreover, according to the research the enormous volume of phishing emails is in fact an indication of the failure of phishing. Naturally, they are many more factors to consider, in particular, are phishers in fact profit-maximization machines or are they willing to sacrifice potential profit for the sake of their own security? Is it all about making big money, or about breaking-even in general?&lt;/p&gt;  &lt;blockquote&gt;&lt;p&gt;“However, as we will show, the economics of phishing are far far worse than this. Rather than sharing a fixed pool of dollars phishing is subject to the tragedy of the commons ; i.e. the pool of dollars shrinks as a result of the efforts of the phishers. A community (all phishers) share a finite resource (the pool of phishable dollars) that has limited ability to regenerate (dollars once phished are not available to other phishers). The tragedy of the commons is that the rational course of action for each individual (phisher) leads to over-exploitation and degradation of the resource (the phishable dollars).”&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;Using the Tragedy of the Commons analogy in this case makes it sound as every phished person’s disposable income to which phishers would eventually have access to is universally the same. Logically, that’s not the case, since a single phished person could prove to be a more profitable catch for a phisher than a hundred phished people, and the number of potentially phishable people is always increasing with more people going online.&lt;/p&gt; &lt;p&gt;Moreover, perhaps not so economic models minded phishers are constantly looking for ways to achieve better efficiency, lower costs, and ways to eat other phishers lunch - by scamming their fellow colleagues. For instance, a related research published in August, 2008, found evidence that &lt;a href="http://blogs.zdnet.com/security/?p=1641"&gt;phishers are in fact backdooring phishing pages and then distributing them for free&lt;/a&gt; so that they can have other phishers do the scam for them. The same backdooring process, even though no properly analyzed in a study, continues to take place at a more advanced and far more profitable level - backdooring web malware exploitation kits and botnet command and control interfaces. Therefore, of the hundred actively participating phishers, eighty could be easily phishing for the other twenty.&lt;/p&gt; &lt;ul&gt;&lt;li&gt;Go through related phishing tactics - &lt;a href="http://blogs.zdnet.com/security/?p=1104"&gt;DIY phishing kits introducing new features&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=2095"&gt;Phishers apply quality assurance, start validating credit card numbers&lt;/a&gt;; &lt;a href="http://blogs.zdnet.com/security/?p=2064"&gt;Lack of phishing attacks data sharing puts $300M at stake annually&lt;/a&gt;&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;There are even more variables to consider. Take internal competition among different phishers. Just because a phisher has just sent a million phishing emails pretending to be from a leading German bank to a million Chinese users, perhaps not knowing that the spamming database he’s using belongs to Chinese citizens, doesn’t mean that the outcome of his campaign would be similar to a fellow phisher that’s taken basic localization and targeting steps into account. With localization of cybecrime taking place as of early 2008, outsourcing the translation process of a particular phishing campaign/email is opening up an entire new space for phishers to more effectively target potential victims. The bottom line here is that the second phisher has a higher chance for success even though they’re attempting to phish the same Chinese users, since he’d be impersonating a local bank and his phishing creatives would be speaking native language.&lt;/p&gt; &lt;p&gt;This is where efficiency and scalability comes into play, a situation pretty similar to that of spam. As long as even a small number of people out of a million phishing emails sent become victims, the phishers would break-even and thus, continue expanding the number of emails sent. This shouldn’t be taken as a failure of phishing in general, instead, it should be considered as a campaign optimization practice attempting to achieve better results by targeting a larger population.&lt;/p&gt; &lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/images/diy_phishing_kit.JPG" title="DIY Phishing Kit"&gt;&lt;img src="http://blogs.zdnet.com/security/images/diy_phishing_kit.JPG" alt="DIY Phishing Kit" align="left" height="132" width="165" /&gt;&lt;/a&gt;Quality assurance is yet another differentiation factor distinguishing the sophisticated phisher from the novice one, who will never get close to the potential market share the sophisticated one is aiming at. Just because all phishers have access to the same quality fakes of legitimate banks, and DIY phishing tools assisting them in redirecting accounting data to a single domain, doesn’t mean that all of them will make the same impact. The experienced ones would achieve a higher average online time for their phishing domains, and would apply better targeting and localization tactics due to the fact that spammers, phishers and malware authors are consolidating and vertically integrating to cut costs and achieve scalability. Phishing may be described as a low-skill, low-reward job in the study, but just like every cybercrime practice the “knowledge workers” in the phishing ecosystem are those getting most of financial rewards, with the rest basically generating noise and in fact often getting busted due to their inexperience, acting as a human shield for the sophisticated phishers.&lt;/p&gt; &lt;p&gt;There’s another issue to consider and that is how much money is a phisher actually looking to make out of his phishing campaigns, and is there in fact a maximum or a minimum to his ambitions? Even though access to someone’s account is obtained, is the phisher actually able to withdraw the money from the account, or is he in fact going to be making money from selling access to the phished account to someone who can do it, thus, monetizing the accounting data instead of using it? Evidence gathered on this practice clearly indicates that novice phishers may in fact never obtain any of the money that they have access it, but again make money out of selling the access to a particular account to those who can.&lt;/p&gt; &lt;p&gt;Phishers may not be making the money that they used to a couple of years ago, but then again phishing has long stopped being an exclusive cybercrime practice - it’s turned into a cybercrime practice “in between” with the phishers breaking-even given the lowering costs and entry barriers into the phishing space in general. And as long as they break-even, millions of phishing emails would continue circulating, again “in between” the rest of their malicious activities.&lt;/p&gt;&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;]&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-3011057654436907057?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/3011057654436907057/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=3011057654436907057' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/3011057654436907057'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/3011057654436907057'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/01/microsoft-study-debunks-phishing.html' title='Microsoft study debunks phishing profitability'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-337487124606803592</id><published>2009-01-08T21:27:00.000-08:00</published><updated>2009-01-08T21:30:27.379-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Passwords'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Anti Virus'/><category scheme='http://www.blogger.com/atom/ns#' term='Hackers'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Web 2.0'/><title type='text'>Bogus LinkedIn profiles serving malware</title><content type='html'>&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/images/linkedin_bogus_malware_player_11.JPG" title="LinkedIn Bogus Profiles Malware"&gt;&lt;img src="http://blogs.zdnet.com/security/images/linkedin_bogus_malware_player_11.JPG" alt="LinkedIn Bogus Profiles Malware" align="left" height="125" width="115" /&gt;&lt;/a&gt;A currently active &lt;a href="http://blog.trendmicro.com/bogus-linkedin-profiles-harbor-malicious-content/"&gt;malware campaign is taking advantage of bogus LinkedIn profiles&lt;/a&gt; impersonating celebrities in an attempt to trick users into clicking on links serving bogus media players. LinkedIn is among the latest social networking services considered as a valuable asset in the arsenal of the blackhat SEO knowledgeable cybecriminal, simply because this approach works.

The group’s efficient way of exploiting Israeli and pro-Israeli web sites through commodity web site defacement tools scanning and exploiting known web application vulnerabilities reached such a peak, that a &lt;a href="http://www.israelnationalnews.com/News/News.aspx/124768"&gt;17 years old member of Team-Evil got busted&lt;/a&gt;. In the ongoing web site defacement attacks, several other well known Muslim hacking groups appear to be working directly cooperating with &lt;strong&gt;Team-Evil&lt;/strong&gt;, such as:&lt;/p&gt; &lt;ul&gt;&lt;li&gt;JURM-TEAM - members include sql_master, Jurm, Dr.Noursoft, RedDoom, Lpooxd, Cyb3rt and Dr.win&lt;/li&gt;&lt;li&gt;Islamic Cr3w - members include Twister and AlH7N00TY&lt;/li&gt;&lt;li&gt;TEAM SPECIAL AGENT - members include PrOf-HaCkEr,Black^Monster, FREEM@N, and R00t-Os&lt;/li&gt;&lt;li&gt;Team-Evil themselves - members include Jurm, Cyber-terrorist, J3ibi9a, Scritpx, Fatna Bant Hmida&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/images/israel_hamas_hackers_2009_55.JPG" title="Israel Hamas Web Site Defacements"&gt;&lt;img src="http://blogs.zdnet.com/security/images/israel_hamas_hackers_2009_55.JPG" alt="Israel Hamas Web Site Defacements" align="left" height="67" width="158" /&gt;&lt;/a&gt;It’s important to point out that the massive web site defacements taking place are not rocket science, they are the low-hanging fruit made possible for them to abuse due to insecurely configured web servers.

While browsers are introducing more features with privacy implications, such as persistent local storage, they have mostly integrated the management of this type of information into a single location. When users want to ensure their privacy with respect to information stored via the browser standard methods, they can go to a single location to clear the data, use a separate browser, or use a working private browsing mode, if available.&lt;/p&gt; &lt;p&gt;Plug-ins need to take extra steps to ensure the privacy of their users. The clear best practices in this area, as exemplified by Google’s Gears, prompts users before allowing a site to store data on their system, holds a per-browser data store, and integrates their management UI into the browser UI. Adobe Flash does none of these things, instead silently allowing web sites to store data, uses one global data store for all browsers, and uses a settings UI accessible only when the user is connected to the Internet.&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;&lt;strong&gt;[ SEE: &lt;a href="http://blogs.zdnet.com/security/?p=2305" rel="bookmark" title="Permanent Link to Major Web browsers fail password protection tests"&gt;Major Web browsers fail password protection tests&lt;/a&gt; ]&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;She called on browser vendors and plug-in vendors to cooperate to make their platforms more trustworthy:&lt;/p&gt; &lt;blockquote&gt;&lt;p&gt;A set of standard APIs to communicate the need for plug-ins to clear data for a particular origin, all sites, or even a date range needs to be developed, and its use required of all plugins. In the absence of these APIs, plugins which require use of any local system resources should prompt before allowing web sites to store data locally, and integrate the management of interface into the standard browser API.&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;In the study, McKinley tested the data storage on modern browsers, including HTTP cookies, HTML 5 session storage, Mozilla Firefox perisistent storage, HTML 5 database storage, IE userData, Adobe Flash and Google Gears.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;[ SEE: &lt;a href="http://blogs.zdnet.com/security/?p=1893" rel="bookmark" title="Permanent Link to Browser Wars 2.0: Firefox scrambles to add ‘private mode’ browsing"&gt;Firefox scrambles to add ‘private mode’ browsing&lt;/a&gt; ]&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;Apple’s Safari on Windows, which offers a “Private Browsing” option, did not fare well:&lt;/p&gt; &lt;blockquote&gt;&lt;p&gt;The HTML 5 Database store on Safari is not cleared when resetting the private data, the user must go to their preferences and select Security, then click the “Show Databases” button on that tab to review or delete databases. For IE 8 Beta 2, the browser must be closed to actually clear the data for the running instance. In each of these cases, it is necessary to perform additional actions to effectively clear this data.&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;And more:&lt;/p&gt; &lt;blockquote&gt;&lt;p&gt;Safari on Windows fared the worst of all in [tests] with respect to private browsing, and did not clear any data at all, either before entering or after exiting the private mode. On OS X, Safari’s behavior was quirky; in no case was the HTML 5 database storage cleared before or after private browsing. Previously set cookies seem to continue to be available if the user entered a private browsing session, but if the user started the browser and went directly into private browsing, it seemed to behave as expected.&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;&lt;em&gt;* Image source: &lt;a href="http://events.ccc.de/congress/2008/Fahrplan/events/2596.en.html"&gt;253C&lt;/a&gt;.

Rightly so — their &lt;a href="http://www.win.tue.nl/hashclash/rogue-ca/"&gt;paper describing the attack&lt;/a&gt; is a fascinating read filled with enough gory details to make any security practitioner salivate.&lt;/p&gt; &lt;p&gt;To summarize, the crux of the attack was the fact that certain certificate authorities (CAs) still use the MD5 algorithm to sign SSL certificates. The researchers exploited this implementation by harnessing some existing academic research on MD5 chosen-prefix collisions and sprinkling in a few additional tricks.&lt;/p&gt; &lt;p&gt;The most frustrating part of this whole debacle is that it should have never happened.&lt;/p&gt;  &lt;p&gt;Like any widely-used cipher, MD5 has been scoured for weaknesses by crypt-analysts since its introduction in 1991. The first significant cracks in the surface appeared at the &lt;a href="http://www.iacr.org/conferences/crypto2004/rump.html"&gt;CRYPTO 2004&lt;/a&gt; conference in August 2004, when Xiaoyun Wang presented a paper entitled &lt;a href="http://eprint.iacr.org/2004/199.pdf"&gt;Collisions for Hash Functions&lt;/a&gt; that described a method for producing MD5 collisions.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;[ SEE: &lt;a href="http://blogs.zdnet.com/security/?p=2339" rel="bookmark" title="Permanent Link to SSL broken! Hackers create rogue CA certificate using MD5 collisions"&gt;SSL broken! Hackers create rogue CA certificate using MD5 collisions&lt;/a&gt; ]&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;History has shown repeatedly that cryptanalysis is an evolutionary process. Each subsequent compromise builds on top of prior work, and each new attack is more practical than the last. The Wang presentation should have been a wake-up call that the clock was ticking on MD5. But, aside from the security community, nobody paid much attention.&lt;/p&gt; &lt;p&gt;At the time, I was employed as a security consultant for @stake, and I can remember revising all of our deliverable templates to remove any mention of MD5 from our best practices or boilerplate text. Even some of my own colleagues were split on whether that was necessary, since the attack didn’t have any practical implications yet. I agreed that we had no reason to act like the sky was falling, but it would only be a matter of time until a practical attack would be discovered. As such, our customers should be advised, at the very least, to eradicate MD5 from their code going forward.&lt;/p&gt; &lt;p&gt;But people tend to be lazy. The typical enterprise mindset can best be summarized as “if it can’t hurt me today, stop bothering me,” and that probably won’t change anytime soon. For an enterprise application, the risk is bounded. If you choose to use a weak hash algorithm in your custom web application, you only hurt yourself and your customers. Apparently, that is a risk people are willing to take, even though switching hash algorithms is a fairly trivial code modification.&lt;/p&gt; &lt;p&gt;A few years later, right on cue, Marc Stevens released a master’s thesis entitled &lt;a href="http://www.win.tue.nl/hashclash/On%20Collisions%20for%20MD5%20-%20M.M.J.%20Stevens.pdf"&gt;On Collisions in MD5&lt;/a&gt; (.pdf), detailing a chosen-prefix attack against MD5. This was a significant breakthrough and one crucial step closer to the practical, &lt;a href="http://blogs.zdnet.com/security/?p=2339"&gt;real-world attack revealed today&lt;/a&gt; in Berlin.&lt;/p&gt; &lt;p&gt;It’s an absolute travesty that the CAs failed to act not only on the Wang research, but on every other MD5 attack that has materialized since. Any organization who is in the business of selling trust should take all possible measures to be trustworthy, and the CAs failed miserably in that regard.&lt;/p&gt; &lt;p&gt;&lt;em&gt;* Chris Eng is senior director of security research at &lt;a href="http://www.veracode.com/blog/"&gt;Veracode&lt;/a&gt;.

In &lt;a href="http://www.win.tue.nl/hashclash/rogue-ca/"&gt;the attack&lt;/a&gt;, the bad guy ends up with his own Certification Authority (CA) that is fully trusted according to every major browser. People are declaring the entire Internet is broken, and that it will be hard to fix.  This is simply not true.&lt;/p&gt; &lt;p&gt;The major misconception I’m seeing over and over is that the problem allows the bad guy to steal the signature off any valid MD5 signature from any certificate on the Internet.&lt;/p&gt; &lt;p&gt;&lt;br /&gt;&lt;strong&gt;[ SEE: &lt;a href="http://blogs.zdnet.com/security/?p=2339"&gt;SSL broken! Hackers create rogue CA certificate&lt;/a&gt; ]&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;Actually, the attack works by a bad guy generating two certificates, one that is just a regular web site certificate, and the other that is a CA certificate.  Then, to get the CA certificate trusted, the bad guy submits the web site cert.  If he can predict the internal values the CA will use when he starts generating the certificate (a process that takes a few days right now), then he will get back a signature that can be pasted onto the CA cert.   That allows the CA to generate new certs to impersonate anybody on the Internet (e.g., Citibank.com).&lt;/p&gt; &lt;p&gt;This means that existing certificates aren’t currently an attack vector, unless they were actually used in an attack.&lt;/p&gt; &lt;p&gt;As a result, this hole is easier to close than people think.  The few CAs signing certs with MD5 need to switch to SHA1 (or something stronger).  That immediately gets rid of the problem for new certs.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;[ Chris Eng: &lt;a href="http://blogs.zdnet.com/security/?p=2341" rel="bookmark" title="Permanent Link to An easy fix ignored"&gt;An easy fix ignored&lt;/a&gt; ]&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;For old certs, the risks are also pretty low.   Just because of the up-front costs of research and development that would have been necessary, there’s a very good chance that bad guys have focused on low-hanging fruit like social engineering, instead of investing the research dollars.&lt;/p&gt; &lt;p&gt;Once the researchers publish technical details on the tricks they used to make the attack cost effective, then probably some bad guys will try, as long as there are still vulnerable CAs.  My guess is that there won’t be.&lt;/p&gt; &lt;p&gt;Even if some bad guys have done all the work, it’s unlikely to have been used more than a handful of times.  Either the bad guys will use their fake CA credentials selectively as to not get caught, or they will get caught quickly, and the certs will be blacklisted.  Either way, the long term risks are negligible, as long as all CAs migrate from MD5 immediately, or take other precautionary measures, such as using a random certificate ID instead of a sequential one.&lt;/p&gt; &lt;p&gt;And for those CAs that don’t take mitigating steps immediately, the operating systems and browsers of the world should move to blacklist them ASAP.&lt;/p&gt; &lt;p&gt;Right now, the only CA that seems to consistently sign using only MD5  (signing with both also thwarts this attack) is RapidSSL/FreeSSL (FreeSSL is owned by RapidSSL, and is used for trial certs).  Who knows why these guys have not migrated away from MD5.  But assuming they do it soon, there is little to worry about.&lt;/p&gt; &lt;p&gt;&lt;em&gt;* John Viega is CEO of &lt;a href="http://blogs.zdnet.com/security/stonewallsoftware.com"&gt;Stonewall Software&lt;/a&gt; and author of several security books including the classic Building Secure Software (Addison Wesley, 2001), and the forthcoming Myths of Security (O’Reilly, 2009).

Hackers create rogue CA certificate using MD5 collisions</title><content type='html'>&lt;p&gt;Using computing power from a cluster of 200 PS3 game consoles and about $700 in test digital certificates, a group of hackers in the U.S. and Europe have found a way to target a &lt;a href="http://www.win.tue.nl/hashclash/Nostradamus/"&gt;known weakness in the MD5 algorithm&lt;/a&gt; to create a rogue Certification Authority (CA), a breakthrough that allows the forging of certificates that are fully trusted by all modern Web browsers.&lt;/p&gt; &lt;p&gt;The research, which &lt;a href="http://events.ccc.de/congress/2008/Fahrplan/track/Hacking/3023.en.html"&gt;will be presented&lt;/a&gt; today by Alex Sotirov (top left) and Jacob Appelbaum (bottom left) at the 25C3 conference in Germany, effectively defeats the way modern Web browsers trust secure Web sites and provides a way for attackers to conduct phishing attacks that are virtually undetectable. &lt;a href="http://blogs.zdnet.com/security/?p=2339"&gt;&lt;img src="http://blogs.zdnet.com/security/images/jacob_appelbaum.png" alt="Jacob Appelbaum" align="left" border="0" height="84" hspace="18" width="100" /&gt;&lt;/a&gt;&lt;/p&gt; &lt;p&gt;The research is significant because there are at least six CAs currently using the weak MD5 cryptographic algorithm in digital signatures and certificates.  The most commonly used Web browsers — including Microsoft’s Internet Explorer and Mozilla’s Firefox — whitelist these CAs, meaning that a fake Certificate Authority can display &lt;em&gt;any&lt;/em&gt; site as secure (with the SSL padlock).&lt;/p&gt; &lt;p&gt;“We basically broke SSL,” Sotirov said in an interview ahead of his 25C3 presentation.&lt;br /&gt;&lt;/p&gt; &lt;blockquote&gt;&lt;p&gt; Our main result is that we are in possession of a “rogue” Certification Authority (CA) certificate. This certificate will be accepted as valid and trusted by many browsers, as it appears to be based on one of the “root CA certificates” present in the so called “trust list” of the browser. In turn, web site certificates issued by us and based on our rogue CA certificate will be validated and trusted as well. Browsers will display these web sites as “secure”, using common security indicators such as a closed padlock in the browser’s window frame, the web address starting with “https://” instead of “http://”, and displaying reassuring phrases such as “This certificate is OK ” when the user clicks on security related menu items, buttons or links.&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;Researchers at the Centrum Wiskunde &amp;amp; Informatica (CWI) in the Netherlands, EPFL in Switzerland, and Eindhoven University of Technology (TU/e) in the Netherlands helped in the design and implementation of the attack using an advanced implementation of a known &lt;a href="http://www.cryptography.com/cnews/hash.html"&gt;MD5 collision construction&lt;/a&gt; and a cluster of more than 200 PlayStation 3 game consoles.&lt;/p&gt; &lt;p&gt;According to Sotirov, a rogue CA in combination with Dan Kaminsky’s DNS attack can have serious consequences:&lt;/p&gt; &lt;blockquote&gt;&lt;p&gt;For example, without being aware of it, users could be redirected to malicious sites that appear exactly the same as the trusted banking or e-commerce websites they believe to be visiting. The web browser could then receive a forged certificate that will be erroneously trusted, and users’ passwords and other private data can fall in the wrong hands. Besides secure websites and email servers, the weakness also affects other commonly used software.&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;Sotirov said the team was able to secure NDAs in advance of briefing the major browser vendors about the problem but because of issues — some practical and some political — there are no straightforward fixes unless the CAs stop using MD5 and move to the more secure SHA-1 algorithm.&lt;/p&gt; &lt;p&gt;To avoid abuse, the team back-dated its rogue CA (it was set only for August 2004) and will not release the private key.   “We’re also not going to release the special code that we used to do the MD5 collisions until later this year,” Sotirov added.&lt;/p&gt; &lt;p&gt;“We don’t anticipate this attack to be repeatable very easily.  If you do a naive implementation, you would need six months to run it successfully,” he added.&lt;/p&gt; &lt;p&gt;Arjen Lenstra, head of EPFL’s Laboratory for Cryptologic Algorithms, the key objective of the research was to stimulate better Internet security with adequate protocols that provide the necessary security.&lt;/p&gt; &lt;p&gt;The key takeaway, according to Lenstra: “It’s imperative that browsers and CAs stop using MD5, and migrate to more robust alternatives such as SHA-2 and the upcoming SHA-3 standard.”&lt;/p&gt; &lt;p&gt;Further details:&lt;/p&gt; &lt;ul&gt;&lt;li&gt;&lt;a href="http://www.win.tue.nl/hashclash/rogue-ca/"&gt;Detailed explanation&lt;/a&gt;&lt;/li&gt;&lt;li&gt;&lt;a href="http://www.phreedom.org/research/rogue-ca/md5-collisions-1.0.ppt"&gt;Slides from the 25c3 presentation&lt;/a&gt;&lt;/li&gt;&lt;li&gt; &lt;a href="https://i.broke.the.internet.and.all.i.got.was.this.t-shirt.phreedom.org/"&gt;Demo site&lt;/a&gt; (set your system date to August 2004 before clicking)&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;Colliding certificates:&lt;/p&gt; &lt;ul&gt;&lt;li&gt;&lt;a href="http://www.win.tue.nl/hashclash/rogue-ca/real.cert.pem"&gt;Real certificate&lt;/a&gt;&lt;/li&gt;&lt;li&gt;&lt;a href="http://www.win.tue.nl/hashclash/rogue-ca/rogue_ca.cert.pem"&gt;Rogue CA certificate&lt;/a&gt;&lt;/li&gt;&lt;/ul&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;]&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-2903459172800844086?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/2903459172800844086/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=2903459172800844086' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/2903459172800844086'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/2903459172800844086'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/01/ssl-broken-hackers-create-rogue-ca.html' title='SSL broken!

While Samsung has some egg on its face, malware that ships on consumer hardware is not as serious of an issue as it may seem.&lt;br /&gt;&lt;br /&gt;Earlier this week &lt;a href="http://www.amazon.com/gp/forum/cd/discussion.html?ie=UTF8&amp;amp;cdForum=Fx20DX5GEB7TUX8&amp;amp;cdThread=Tx2LOAXBDR3N47W"&gt;Amazon alerted its customers to an issue affecting the installation CD that shipped with the Samsung SPF-85H 8 inch Digital Picture Frame&lt;/a&gt;. Apparently the CD shipped with a copy of the W32.Sality.AE virus. Amazon is recommending that people download a recent copy of the application directly from Samsung’s website rather than using the CD.&lt;/p&gt; &lt;p&gt;So yes, this is embarrassing for Samsung. It shows that either they or the subcontractor who cut the CD need to tighten up their processes surrounding manufacturing systems. There is no reason for those machines to be exposed to malware, let alone not run up-to-date anti-virus to catch these infections.&lt;/p&gt; &lt;p&gt;The customers have a pretty low likelihood of being infected by this malware, though. Any system running up-to-date anti-virus would have been guaranteed to spot the potential infection, as the delay between when the CD was first cut and when the customer attempted to install the application was far longer than the average amount of time it takes for a piece of malware to be detected by an anti-virus package. If the system wasn’t running an up-to-date anti-virus package, well, it probably had oodles of malware already, and the marginal cost of one more infection is pretty small.&lt;/p&gt; &lt;p&gt;I suspect next year Samsung will be asking Santa for security people who are tightwads about compliance.&lt;/p&gt;&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;]&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-4878753383553106419?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/4878753383553106419/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=4878753383553106419' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/4878753383553106419'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/4878753383553106419'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/01/santa-left-virus-under-christmas-tree.html' title='Santa left a virus under the Christmas tree'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-8923129720590724402</id><published>2009-01-08T20:48:00.000-08:00</published><updated>2009-01-08T20:51:17.486-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Windows Vista'/><category scheme='http://www.blogger.com/atom/ns#' term='Vulnerability Research'/><category scheme='http://www.blogger.com/atom/ns#' term='Zero-Day  Attacks'/><category scheme='http://www.blogger.com/atom/ns#' term='Patch Watch'/><category scheme='http://www.blogger.com/atom/ns#' term='Exploit Code'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Microsoft'/><title type='text'>Microsoft pours cold water on WMP flaw warning</title><content type='html'>&lt;span style="display: none;" class="more"&gt;&lt;a href="http://updates.zdnet.com/tags/Digital+Media.html"&gt;Media&lt;/a&gt;,  &lt;a href="http://updates.zdnet.com/tags/Security.html"&gt;Security&lt;/a&gt;,  &lt;a href="http://updates.zdnet.com/tags/Consumer+Electronics.html"&gt;Consumer Electronics&lt;/a&gt;&lt;/span&gt;

Microsoft is pouring cold water on public reports of a serious code execution vulnerability in the newest versions of its Windows Media Player software.&lt;/p&gt; &lt;p&gt;Following the release of proof-of-concept code alongside a claim that the bug can be remotely exploitable to launch arbitrary code, a Microsoft spokesman insists this “is not a product vulnerability.”&lt;/p&gt; &lt;p&gt;Here’s Microsoft’s full statement:&lt;/p&gt;  &lt;blockquote&gt;&lt;p&gt;Microsoft is aware of a falsely reported vulnerability in Microsoft Windows Media Player Dec. 25, 2008.  Microsoft investigated the claim and found that this is not a product vulnerability.  Microsoft confirmed that the reported crash is not exploitable and does not allow an attacker to execute arbitrary code, as was incorrectly claimed in the public report.&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;The statement follows an &lt;a href="http://www.securitytracker.com/alerts/2008/Dec/1021495.html"&gt;advisory&lt;/a&gt; from researcher Laurent Gaffie that a remote user can create a specially crafted WAV, SND, or MIDI file to trigger an integer overflow and execute arbitrary code on the target system.&lt;/p&gt; &lt;p&gt;Gaffie claims the bug affects all versions of the media player, including WMP 11&lt;span style="font-size:-1;"&gt;&lt;span style="font-family:Arial, Helvetica;"&gt;.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt; &lt;p&gt;&lt;strong&gt;UPDATE:&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;Jonathan Ness from Microsoft’s SWI team &lt;a href="http://blogs.technet.com/swi/archive/2008/12/29/windows-media-player-crash-not-exploitable-for-code-execution.aspx"&gt;provides more details on why this bug isn’t exploitable&lt;/a&gt; and says it was already discovered internally and slated for fixing in a future service pack:&lt;/p&gt; &lt;blockquote&gt;&lt;p&gt;We found this already through our internal fuzzing efforts. It was correctly triaged at the time as a reliability issue with no security risk to customers.  We do like to get these reliability issues fixed in a future service pack or a future version of the platform whenever possible.  This particular bug, for example, has already been fixed in Windows Server 2003 Service Pack 2.&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;On &lt;a href="http://blogs.technet.com/msrc/archive/2008/12/29/questions-about-vulnerability-claim-in-windows-media-player.aspx"&gt;the MSRC blog&lt;/a&gt;,  Christopher Budd laments the fact that the researcher went public with an advisory instead of reporting it directly to Microsoft.&lt;/p&gt; &lt;p&gt;&lt;em&gt;* Image source: &lt;a href="http://www.flickr.com/photos/luchoedu/2453280726/"&gt;LuChOeDu Flickr photostream&lt;/a&gt; (Creative Commons 2.0)&lt;br /&gt;&lt;/em&gt;&lt;/p&gt;&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;] &lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-8923129720590724402?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/8923129720590724402/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=8923129720590724402' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/8923129720590724402'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/8923129720590724402'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/01/microsoft-pours-cold-water-on-wmp-flaw.html' title='Microsoft pours cold water on WMP flaw warning'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-830952201644280981</id><published>2009-01-08T06:03:00.000-08:00</published><updated>2009-01-08T06:09:42.896-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Windows Vista'/><category scheme='http://www.blogger.com/atom/ns#' term='SQL Injection'/><category scheme='http://www.blogger.com/atom/ns#' term='Patch Watch'/><category scheme='http://www.blogger.com/atom/ns#' term='Spyware and Adware'/><category scheme='http://www.blogger.com/atom/ns#' term='Hackers'/><category scheme='http://www.blogger.com/atom/ns#' term='Pen testing'/><category scheme='http://www.blogger.com/atom/ns#' term='Microsoft Windows XP'/><category scheme='http://www.blogger.com/atom/ns#' term='Botnets'/><title type='text'></title><content type='html'>&lt;a href="http://blogs.zdnet.com/security/?p=2328#comments"&gt;&lt;span&gt;&lt;/span&gt;&lt;/a&gt;&lt;a href="http://blogs.zdnet.com/security/images/pc_zero1_symantec_china.jpg" title="Symantec Internet Explorer Zero Day China"&gt;&lt;img src="http://blogs.zdnet.com/security/images/pc_zero1_symantec_china.jpg" alt="Symantec Internet Explorer Zero Day China" align="left" height="116" width="163" /&gt;&lt;/a&gt;Once again confirming the trend of having more legitimate sites serving exploits and malware than purely malicious ones, Chinese hackers have been &lt;a href="http://isc.sans.org/diary.html?storyid=5464&amp;amp;rss"&gt;keeping themselves busy&lt;/a&gt; during the last couple of days, &lt;a href="https://forums.symantec.com/t5/Vulnerabilities-Exploits/Rise-of-IE-Zero-Day-Through-SQL-Injection/ba-p/372832#A182"&gt;launching massive SQL injection attacks affecting over 100,000 web sites&lt;/a&gt;. &lt;p&gt;The &lt;a href="http://www.shadowserver.org/wiki/pmwiki.php?n=Calendar.20081211"&gt;SQL injection attacks&lt;/a&gt; serving the &lt;a href="http://www.microsoft.com/technet/security/bulletin/ms08-078.mspx"&gt;just patched Internet Explorer XML parsing exploit&lt;/a&gt;, are launched by several different Chinese hacking groups, and with several exceptions, are primarily targeting Asian countries which is a pretty logical move given the fact that it’s a password stealing malware for online games that is served at the bottom line.&lt;/p&gt; &lt;p&gt;Which is the most targeted country?&lt;/p&gt; &lt;p&gt;According to some stats from Symantec, China ironically remains the most actively targeted country by the IE exploit, ironically in the sense that it was Chinese researchers that leaked the exploit at the first place. Moreover, the 100,000 web sites cited as being infected by Symantec, should be taken as a very conservative metric, since more domains are being injected and as previous campaigns, the number of affected sites could change pretty fast.&lt;/p&gt; &lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/images/sql_injection_international_ie_oday.JPG" title="SQL Injection Internet Explorer Zero Day"&gt;&lt;img src="http://blogs.zdnet.com/security/images/sql_injection_international_ie_oday.JPG" alt="SQL Injection Internet Explorer Zero Day" align="left" height="161" width="153" /&gt;&lt;/a&gt;Consider for a while the big picture. With or without a patch for the IE exploit, committing cybercrime through the exploitation of already patched client-side vulnerabilities would continue growing - it has been throughout the entire 2008. Despite being old-fashioned compared to Russian cybercriminals that would have included the exploit within their &lt;a href="http://blogs.zdnet.com/security/?p=2217"&gt;web malware exploitation kits&lt;/a&gt; and started serving banker malware instead of password stealing malware, the Chinese attackers appear to be well aware of this trend, and therefore all of the IE exploit serving sites are also serving several other exploits targeting Adobe’s Flash, Acrobat Reader and RealPlayer for starters.&lt;/p&gt; &lt;p&gt;Recent studies continue emphasizing on the fact that &lt;a href="http://www.techzoom.net/publications/insecurity-iceberg/index.en"&gt;millions of users not only continue browsing the web using insecure browsers&lt;/a&gt;, but also, are so browser vulnerabilities centered and they &lt;a href="http://secunia.com/blog/11/"&gt;ignore the rest of the software&lt;/a&gt; running on their PCs as a &lt;a href="http://secunia.com/blog/37/"&gt;potential infection vector given they’re running an insecure versions of it&lt;/a&gt; - and yes they are. Cybercriminals are aware of this insecure Internet browsing, and are therefore including &lt;a href="http://blogs.zdnet.com/security/images/xmas_web_malware_exploitation_kit_2.JPG"&gt;sets of exploits&lt;/a&gt; targeting each and every &lt;a href="http://blogs.zdnet.com/security/images/xmas_web_malware_exploitation_kit_3.JPG"&gt;version known to be vulnerable&lt;/a&gt; of a particular software in order to &lt;a href="http://blogs.zdnet.com/security/images/live_exploit_kit_sample.JPG"&gt;increase the chances for a successful infection&lt;/a&gt;. This particular SQL injection attack is the most recent example of this mentality.&lt;/p&gt; &lt;p&gt;In 2008, cybercriminals continue infecting thousands of new hosts on daily basis using 2007’s critical vulnerabilities, because instead of patching vulnerable software, the majority of end users remain comfortable with their &lt;a href="http://blogs.zdnet.com/security/?p=2030"&gt;false feeling of security&lt;/a&gt;.&lt;/p&gt;&lt;p&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;] &lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-830952201644280981?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/830952201644280981/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=830952201644280981' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/830952201644280981'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/830952201644280981'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2009/01/once-again-confirming-trend-of-having.html' title=''/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-4386036251341652090</id><published>2009-01-08T05:57:00.000-08:00</published><updated>2009-01-08T06:03:31.826-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Vulnerability Research'/><category scheme='http://www.blogger.com/atom/ns#' term='Zero-Day  Attacks'/><category scheme='http://www.blogger.com/atom/ns#' term='Patch Watch'/><category scheme='http://www.blogger.com/atom/ns#' term='Exploit Code'/><category scheme='http://www.blogger.com/atom/ns#' term='DDos Attack'/><category scheme='http://www.blogger.com/atom/ns#' term='Viruses And Worms'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Data  theft'/><category scheme='http://www.blogger.com/atom/ns#' term='Arbitrary  Code  Execution'/><category scheme='http://www.blogger.com/atom/ns#' term='Pen testing'/><category scheme='http://www.blogger.com/atom/ns#' term='Microsoft'/><title type='text'>Microsoft confirms critical SQL Server vulnerability</title><content type='html'>&lt;p&gt;&lt;img src="http://blogs.zdnet.com/security/images/sql_server.jpg" alt="MS confirms SQL Server vulnerability, posts workarounds" align="left" border="0" hspace="20" /&gt;Microsoft late Monday issued a pre-patch advisory confirming a remote code execution vulnerability affecting its SQL Server line.&lt;/p&gt; &lt;p&gt;The vulnerability, &lt;a href="http://www.sec-consult.com/files/20081209_mssql-sp_replwritetovarbin_memwrite.txt"&gt;publicly disclosed with exploit code&lt;/a&gt; more than two weeks ago, affects Microsoft SQL Server 2000, Microsoft SQL Server 2005, Microsoft SQL Server 2005 Express Edition, Microsoft SQL Server 2000 Desktop Engine (MSDE 2000), Microsoft SQL Server 2000 Desktop Engine (WMSDE), and Windows Internal Database (WYukon).&lt;/p&gt; &lt;p&gt;From the advisory:&lt;/p&gt;  &lt;p&gt;&lt;strong&gt;[ SEE: &lt;a href="http://blogs.zdnet.com/security/?p=2317"&gt;As attacks escalate, MS readies emergency IE patch&lt;/a&gt;  ]&lt;/strong&gt;&lt;/p&gt; &lt;blockquote&gt;&lt;p&gt;Microsoft is aware that exploit code has been published on the Internet for the vulnerability addressed by this advisory. Our investigation of this exploit code has verified that it does not affect systems that have had the workarounds listed below applied. Currently, Microsoft is not aware of active attacks that use this exploit code or of customer impact at this time.&lt;/p&gt; &lt;p&gt;In addition, due to the mitigating factors for default installations of MSDE 2000 and SQL Server 2005 Express, Microsoft is not currently aware of any third-party applications that use MSDE 2000 or SQL Server 2005 Express which would be vulnerable to remote attack.

Not surprising, considering that &lt;a href="http://blogs.zdnet.com/security/?p=1212"&gt;Apple refused to admit Safari’s carpet-bombing flaw&lt;/a&gt; at the first place, Google is too, downplaying it  : &lt;blockquote&gt;&lt;p&gt;“&lt;strong&gt;Lenssen&lt;/strong&gt;: There are ways to make Chrome automatically download a file without the user confirming this (at least using Chrome’s default options). Don’t you consider that a potential problem?&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Rakowski&lt;/strong&gt;: On its own, downloading a file isn’t dangerous. It can be annoying if a site tries to download a bunch of files to fill up your hard drive, but there are other ways to do things like that and it hasn’t become a problem. The danger arises when an automatically downloaded file can be automatically executed. We’ve taken steps to prevent this in Google Chrome and will continue to make sure that this is the case. “&lt;/p&gt;&lt;/blockquote&gt; &lt;p&gt;In reality, the danger arises from an &lt;strong&gt;automatically downloaded malicious file&lt;/strong&gt; with a changed icon and a descriptive title or &lt;a href="http://ddanchev.blogspot.com/2008/07/malware-and-office-documents-joining.html"&gt;backdoored but legitimate Windows Office files&lt;/a&gt; downloaded without any notice, not from dumping hundreds of files on a particular desktop. Causing a denial of service attack next to dumping a piece of crimeware isn’t really going to do much for a malicious attacker wanting your Ebanking data.&lt;/p&gt; &lt;p&gt; The level or &lt;a href="http://blogs.zdnet.com/security/?p=1847"&gt;exploitability of any of Chrome’s vulnerabilities&lt;/a&gt; is proportional with its market share, and whereas there are no&lt;a href="http://blogs.zdnet.com/security/images/icon_changer_malware_binary.gif" title="Icon Changer"&gt;&lt;img src="http://blogs.zdnet.com/security/images/icon_changer_malware_binary.gif" alt="Icon Changer" align="right" width="157" height="129" /&gt;&lt;/a&gt; currently active malware attacks taking advantage of this particular flaw allowing them to dump a file on a visitor’s desktop, leaving this opportunity open won’t go unnoticed. As it appears, coming up with a simple script filling up someone’s hard drive upon visiting a specific site, seems to be the way to raise awareness on the potential for old school malware attacks relying on changed icons and the binaries spread across the desktop, and hopefully attract Google’s attention to the possibilities for abuse.&lt;/p&gt; &lt;p&gt;Chrome’s been receiving lots of criticism internationally, with &lt;a href="http://blogoscoped.com/archive/2008-09-07-n33.html"&gt;Germany’s Federal Office for Information Security&lt;/a&gt; urging users not to use the browser, next to the Dutch Computer Emergency Response Team (Govcert.nl) recommending its use &lt;a href="http://www.computerworld.co.ke/articles/2008/09/09/security-agencies-rally-against-google-chrome"&gt;only in test environments&lt;/a&gt; due to the BETA release.

The issue was reported privately to Google.  &lt;a href="http://src.chromium.org/viewvc/chrome?view=rev&amp;amp;revision=1797"&gt;Fix details here&lt;/a&gt;.&lt;/li&gt;&lt;li&gt;Fixes an &lt;a href="http://code.google.com/p/chromium/issues/detail?id=122"&gt;out of bounds memory read&lt;/a&gt; when parsing URLs ending with :%.  This is a low risk that can be used to crash the entire browser, possibly causing loss of data in the current session.  &lt;a href="http://src.chromium.org/viewvc/chrome?view=rev&amp;amp;revision=1760"&gt;Fix information here&lt;/a&gt;.&lt;/li&gt;&lt;li&gt;The update also changes the default Downloads directory if it is set to Desktop to ensure that Desktop cannot be the default. This mitigates &lt;a href="http://src.chromium.org/viewvc/chrome?view=rev&amp;amp;revision=1793"&gt;the risk of malicious cluttering of the desktop&lt;/a&gt; (aka carpet bombing) with unwanted downloads, which can lead to executing unwanted files.&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;&lt;strong&gt;[ SEE: &lt;a href="http://blogs.zdnet.com/security/?p=1858" rel="bookmark" title="Permanent Link to Google Chrome vulnerabilities starting to pile up"&gt;Google Chrome vulnerabilities starting to pile up&lt;/a&gt; ]&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;Curiously,  user agent for the fully patched version of Chrome (version 0.2.149.29) is still showing WebKit 525.13 (Safari 3.1) , meaning that &lt;a href="http://blogs.zdnet.com/security/?p=1843"&gt;Aviv Raff’s two-click PC takeover vulnerability&lt;/a&gt; is still unpatched.&lt;/p&gt; &lt;p&gt;&lt;img src="http://blogs.zdnet.com/security/images/chrome_patch1.png" alt="Google patches ‘critical’ Chrome code execution flaws" /&gt;&lt;/p&gt; &lt;p&gt;I just tested Raff’s proof-of-concept that combines two flaws — one in Safari and one in Java — and was still able to execute code without warning.

The problem affects all of the different browsers except something like lynx.  The issue has nothing to do with JavaScript so turning JavaScript off in your browser will not help you.  It’s a fundamental flaw with the way your browser works and cannot be fixed with a simple patch.  With this exploit, once you’re on the malicious web page, the bad guy can make you click on any link, any button, or anything on the page without you even seeing it happening.&lt;/em&gt;&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;&lt;strong&gt;[ SEE: &lt;a href="http://blogs.zdnet.com/security/?p=1733" rel="bookmark" title="Permanent Link to Adobe Flash ads launching clipboard hijack attack"&gt;Adobe Flash ads launching clipboard hijack attack&lt;/a&gt; ]&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;If that’s not scary enough, consider than the average end user would have no idea what’s going on during a Clickjack attack.&lt;/p&gt; &lt;ul&gt;&lt;li&gt;&lt;em&gt;Ebay, for example, would be vulnerable to this since you could embed javascript into the web page, although, javascript is not required to exploit this.  “It makes it easier in many ways, but you do not need it.”  Use lynx to protect yourself and don’t do dynamic anything.  You can “sort of” fill out forms and things like that.  The exploit requires DHTML.  Not letting yourself be framed (framebusting code) will prevent cross-domain clickjacking, but an attacker can still force you to click any links on their page.  Each click by the user equals a clickjacking click so something like a flash game is perfect bait. &lt;/em&gt;&lt;/li&gt;&lt;/ul&gt; &lt;p&gt;According to Hansen, the threat scenario was discussed with both Microsoft and Mozilla and they concur independently that this is a tough problem with no easy solution at the moment.&lt;/p&gt; &lt;p&gt;Grossman confirmed that the latest versions of Internet Explorer (including version 8) and Firefox 3 are affected.&lt;/p&gt; &lt;ul&gt;&lt;li&gt; &lt;em&gt;In the meantime, the only fix is to disable browser scripting and plugins. We realize this doesn’t give people much technical detail to go on, but it’s the best we can do right now.&lt;/em&gt;&lt;/li&gt;&lt;/ul&gt;&lt;a href="http://blogs.zdnet.com/security/?p=1837" rel="bookmark" title="Permanent Link to Google Chrome, the security tidbits"&gt;[&lt;/a&gt;Source&lt;a href="http://blogs.zdnet.com/security/?p=1975#more-1975"&gt;: zdnet&lt;/a&gt;]&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1527176046331538077-9162376772863869771?l=4xsecurityteam.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://4xsecurityteam.blogspot.com/feeds/9162376772863869771/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1527176046331538077&amp;postID=9162376772863869771' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/9162376772863869771'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1527176046331538077/posts/default/9162376772863869771'/><link rel='alternate' type='text/html' href='http://4xsecurityteam.blogspot.com/2008/12/clickjacking-researchers-raise-alert.html' title='Clickjacking: Researchers raise alert for scary new cross-browser exploit'/><author><name>Mzer0</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1527176046331538077.post-3181045271478243772</id><published>2008-12-19T04:43:00.000-08:00</published><updated>2008-12-19T04:45:53.108-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Patch Watch'/><category scheme='http://www.blogger.com/atom/ns#' term='Mozilla'/><category scheme='http://www.blogger.com/atom/ns#' term='Exploit Code'/><category scheme='http://www.blogger.com/atom/ns#' term='DDos Attack'/><category scheme='http://www.blogger.com/atom/ns#' term='Malware'/><category scheme='http://www.blogger.com/atom/ns#' term='Data  theft'/><category scheme='http://www.blogger.com/atom/ns#' term='Pen testing'/><category scheme='http://www.blogger.com/atom/ns#' term='Google'/><category scheme='http://www.blogger.com/atom/ns#' term='Browsers'/><category scheme='http://www.blogger.com/atom/ns#' term='Botnets'/><title type='text'>Firefox rushes out fix for password manager bug</title><content type='html'>&lt;p&gt;&lt;img src="http://blogs.zdnet.com/security/images/ff_3.png" alt="Firefox rushes out fix for password manager bug" align="left" border="0" width="83" height="74" hspace="12" /&gt;Just days after shipping a patch for &lt;a href="http://blogs.zdnet.com/security/?p=1962"&gt;a dozen serious security holes in Firefox&lt;/a&gt;, Mozilla has rushed out another version to fix an annoying password manager bug.&lt;/p&gt; &lt;p&gt;The newest &lt;a href="http://www.mozilla.com/en-US/firefox/3.0.3/releasenotes/"&gt;Firefox 3.0.3&lt;/a&gt; basically fixes a problem where users were unable to retrieve saved passwords or save new passwords.&lt;/p&gt; &lt;p&gt;Firefox’s Mike Beltzner explains:&lt;/p&gt; &lt;ul&gt;&lt;li&gt;The symptom is that users who have password data stores with non-ASCII data saved as something other than UTF-8 (more common for people who have saved passwords on IDN domains or non en-US domains) will not be able to access their saved passwords or create any new saved passwords.
