Newsletters: @RISK

@RISK provides a reliable weekly summary of (1) newly discovered attack vectors, (2) vulnerabilities with active new exploits, (3) insightful explanations of how recent attacks worked, and other valuable data

A key purpose of the @RISK is to provide the data that will ensure that the 20 Critical Controls (the US and UK benchmark for effective protection of networked systems) continue to be the most effective defenses for all known attack vectors. But since it is also valuable for security practitioners, SANS is making it available to the 145,000 security practitioners who have completed SANS security training and others at their organizations who hope to stay current with the offensive methods in use.

TOP VULNERABILITY THIS WEEK: A new zero-day attack for Adobe Acrobat Reader X has been discovered, according to Russian firm Group-IB. While attacks to date appear to be limited, due to the need for user interaction before exploitation can take place, it can be assumed that underground researchers are working on a mechanism to automate the exploit, so that it can be used in drive-by downloads and exploit kits.

NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Adobe Flash 0-Day
Description: A new Adobe Acrobat Reader X memory corruption vulnerability was recently announced by Group-IB, a Russian cybersecurity firm. While initial reports were that it was to be added to the Blackhole Exploit Kit immediately, researchers soon noted that exploiting the bug required manual user interaction - specifically, the malicious file would have to be closed like a normal document - which would make it unsuitable for Blackhole and other automated exploitation systems. Exploits have been limited in the wild thus far, but given the difficulty of bypassing Adobe's recently added sandboxing and other security features, cybercriminals are likely working on ways to automate exploitation already. As no patch currently exists, potentially vulnerable users should exercise caution when opening potentially suspicious PDF documents.

Title: 64-bit Linux Rootkit Uses Novel Techniques
Description: A new type of 64-bit Linux rootkit was discovered in the wild last week, after an infected user posted details from an infected server on the Full-Disclosure mailing list. The rootkit was found injecting malicious iframes into all HTTP responses served up by the victim's nginx web server, a popular open-source, lightweight system programmed by Russian-based company Nginx, Inc. This technique, which can easily be used to assist in drive-by downloads and other exploit kit style behavior, is a fascinating new twist on cybercriminals' efforts to continue infecting large swaths of the public for use in worldwide botnets.

Title: Novell File Reporter 0-Day Exploits Available in Metasploit
Description: Multiple remote file retrieval vulnerabilities plus a remote code execution bug were announced last week in Novell's File Reporter software, used for coordinating data storage across multiple filesystems and/or storage solutions. The vulnerabilities have already been added to Metasploit, and as no patch currently exists, exploits are presumed to be occurring in the wild. Potentially impacted customers are urged to firewall off their devices appropriately until a patch is released.
