myOpenID XSS : One of the Largest OpenID provider is Vulnerable

One of the One of the Largest Independent OpenID provider "myOpenID" is Vulnerable to Cross Site Scripting (XSS) ,Discovered by "SeeMe" - Member of Inj3ct0r Team. Cross Site Scripting (or XSS) is one of the most common application-layer web attacks.


What Hacker can do - "The attackers can steal the session ID of a valid user using XSS. The session ID is very valuable because it is the secret token that the user presents after login as proof of identity until logout. If the session ID is stored in a cookie, the attackers can write a script which will run on the user's browser, query the value in the cookie and send it to the attackers. The attackers can then use the valid session ID to browse the site without logging in. The script could also collect other information from the page, including the entire contents of the page".

CrySyS Duqu Detector Open source Toolkit Released


Researchers at the Laboratory of Cryptography and System Security (CrySyS) in Hungary confirmed the existence of the zero-day vulnerability in the Windows kernel, according to security researchers tracking the Stuxnet-like cyber-surveillance Trojan.

The Laboratory of Cryptography and System Security (CrySyS) has released an open-source toolkit that can find traces of Duqu infections on computer networks.The open-source toolkit, from the Laboratory of Cryptography and System Security (CrySyS), contains signature- and heuristics-based methods that can find traces of Duqu infections where components of the malware are already removed from the system.

They make a release that "The toolkit contains signature and heuristics based methods and it is able to find traces of infections where components of the malware are already removed from the system.The intention behind the tools is to find different types of anomalies (e.g., suspicious files) and known indicators of the presence of Duqu on the analyzed computer. As other anomaly detection tools, it is possible that it generates false positives. Therefore, professional personnel is needed to elaborate the resulting log files of the tool and decide about further steps."

This toolkit contains very simple, easy-to-analyze program source code, thus it may also be used in special environments, e.g. in critical infrastructures, after inspection of the source code (to check that there is no backdoor or malicious code inside) and recompiling.

Windows Kernel Zero Day Vulnerability Found in Duqu Installer

Duqu malware attack exploited a zero-day vulnerability in the Windows kernel, according to security researchers tracking the Stuxnet-like cyber-surveillance Trojan. The vulnerability has since been reported to Microsoft and Microsoft is working on a fix for the kernel vulnerability right now.

Researchers at the Laboratory of Cryptography and System Security (CrySyS) in Hungary confirmed the existence of the zero-day vulnerability and exploit in a brief note posted to its web site.
Our lab, the Laboratory of Cryptography and System Security (CrySyS) pursued the analysis of the Duqu malware and as a result of our investigation, we identified a dropper file with an MS 0-day kernel exploit inside. We immediately provided competent organizations with the necessary information such that they can take appropriate steps for the protection of the users.


The installer file is a Microsoft Word document (.doc) that exploits a previously unknown kernel vulnerability that allows code execution. We contacted Microsoft regarding the vulnerability and they're working diligently towards issuing a patch and advisory. When the file is opened, malicious code executes and installs the main Duqu binaries. The chart below explains how the exploit in the Word document file eventually leads to the installation of Duqu.

Other security vendors have reported infections in the following countries: • Austria • Hungary • Indonesia • United Kingdom • Iran - infections different from those observed by Symantec.

"Microsoft is collaborating with our partners to provide protections for a vulnerability used in targeted attempts to infect computers with the Duqu malware. We are working diligently to address this issue and will release a security update for customers through our security bulletin process," Jerry Bryant, group manager of response communications in Microsoft's Trustworthy Computing group said in a statement.

You can find Symantec updated whitepaper (version 1.3) here. Key updates in the Symantec whitepaper include:• An unpatched zero-day vulnerability is exploited through a Microsoft Word document and installs Duqu
• Attackers can spread Duqu to computers in secure zones and control them through a peer-to-peer C&C protocol
• Six possible organizations in eight countries have confirmed infections
• A new C&C server (77.241.93.160) hosted in Belgium was discovered and has been shut down.

w3af v.1.1 - Web Application Attack and Audit Framework Released

w3af is a Web Application Attack and Audit Framework. The project's goal is to create a framework to find and exploit web application vulnerabilities that is easy to use and extend. To read our short and long term objectives. w3af is much more than a piece of software, w3af is a community that breathes Web Application Security.
Change Log:
* Considerably increased performance by implementing gzip encoding
* Enhanced embedded bug report system using Trac's XMLRPC
* Fixed hundreds of bugs * Fixed critical bug in auto-update feature
* Enhanced integration with other tools (bug fixed and added more info to the file)
