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.

@RISK: The Consensus Security Vulnerability Alert

Vol. 12, Num. 50

Providing a reliable, weekly summary of newly discovered attack vectors, vulnerabilities with active exploits, and explanations of how recent attacks worked.



MOST POPULAR MALWARE FILES 12/6/2012 - 12/12/2012

TOP VULNERABILITY THIS WEEK: A theoretical implementation of a Tor-powered botnet described in a Reddit thread in April was discovered in the wild by researchers last week. Based on the wildly popular Zeus malware, this particular threat is designed for maximum evasion capabilities, and may prompt copycat bots using the widely deployed Tor anonymity software.

Title: Tor-powered botnet jumps from a description on Reddit to reality
Description: After a popular Reddit thread in April of 2012 described how a botnet could be built using the Tor anonymizing proxy system, in order to reduce the likelihood of discovery and takedown, researchers with the Metasploit project discovered a modified Zeus binary that used Tor in a manner almost identical to what was discussed in the thread. While such an operation has been discussed in theory for years, including a 2010 Defcon talk on the subject, few, if any such botnets have been observed in the wild to date. The success of this particular botnet, however, is likely to spur imitators going forward.

Title: ExploitHub site compromised, private exploit database stolen
Description: IDS and Antivirus testing firm NSS Labs, whose ExploitHub site was set up in 2010 as a marketplace for private exploits used (ostensibly) in penetration tests and other defense-validating scenarios, had that project's server compromised by the more black hat group 1337day, whose site offers a competing database of exploits. The compromise is likely to produce turmoil within the industry, public release of some of the ExploitHub bugs, and/or other related fallout. Additionally, it serves as a warning that even security vendors should be vigilant in securing their systems, as no one is immune to attack on improperly managed servers.

Title: Targeted malware using CVE-2012-0158 persists
Description: Multiple researchers have lately discovered new targeted attacks circulating in the wild that target CVE-2012-0158, an RTF file format vulnerability which was patched in April of this year. Thanks to their relatively simple format and the large number of sample exploits available in the wild, RTFs have been a favorite of targeted attackers in 2012, with targets ranging from Tibetan protesters to defense contractors worldwide.

Title: Microsoft releases monthly patch update
Description: Microsoft released patches for vulnerabilities in a number of components this Tuesday. While none are known to have exploits currently circulating in the wild, several should be straightforward to exploit, including a new RTF vulnerability that is likely to be used in targeted attacks going forward. Users should, as usual, patch as soon as feasible.
