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: New variants of the popular Gozi keylogging trojan, a favorite of cybercriminals intent on stealing banking credentials and other sensitive data since 2005, have been observed in the wild over the past week. The trojan has been successful over the years by continually morphing in an effort to evade IDS and AV systems, and the latest variant does exactly that.

Special Webcast: A Look at Exploiting Windows 7 and Windows 8. Tuesday, August 14, 2012 at 1:00 PM EDT featuring Stephen Sims. In this one hour presentation we will take a look at the various exploit mitigation controls added to the Windows 7 and Windows 8 operating systems, and the techniques used to deal with these controls as a penetration tester.

NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Malvertising Campaign Uses Novel iframe Hiding Technique
Description: Hidden HTML iframes are a common hallmark of malicious web content. The Sourcefire VRT recently observed a widespread malvertising campaign in the wild which was employing a novel method for hiding its malicious iframe, which was designed to evade existing IDS and AV techniques.
Reference: http://vrt-blog.snort.org/2012/08/stupid-css-tricks.html
Snort SID: 23618
ClamAV: N/A

Title: Gozi Trojan Continues To Spread In The Wild
Description: The Sourcefire VRT has observed new variants of the Gozi keylogging trojan spreading in the wild this week. This trojan, which has been stealing banking credentials and other valuable user data since 2005, has continued to prove effective in the field due to its constantly shifting behavior and intelligent evasion methods. The iteration currently being observed in the field has subtle differences from the most recent variants, but is different enough to warrant updated coverage by many IDS and AV tools.

http://en.wikipedia.org/wiki/Gozi_(Trojan_horse)
Snort SID: 23635
ClamAV: Trojan.Agent-303654

Title: Apache Struts Java Framework Remote Code Executin
Description: The Apache Struts framework, a popular plugin for deploying Java-based web applications, is vulnerable to a remote code execution attack. Specifically, the ExceptionDelegator component, when handling certain input values, can be fooled into simply executing arbitrary Java code. Public exploit code exists, and the Sourcefire VRT has seen signs of the bug being exploited in the wild. Administrators are urged to patch their systems promptly.
Reference: http://issues.apache.org/jira/browse/WW-3668
http://www.exploit-db.com/exploits/18329/
Snort SIDs: 21072, 21073, 23631
ClamAV: N/A

Title: Blackhole Exploit Kit JavaScript Evasion Methods Evolving
Description: One of the reasons the Blackhole Exploit Kit is so popular among cybercriminals is that it is constantly updated to evade detection. The Sourcefire VRT has observed a recent update in the field, which targets some of the keys previously used for IDS detection. While old signatures are still useful, as many versions of the kit exist in the wild, new signatures have been created to handle the latest revision.
