@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: Google researcher Tavis Ormandy provided exploit code for an unpatched local kernel vulnerability in Windows this week, after having first published details on the Full-Disclosure mailing list in mid-May. The release coincides with Google's shift from giving vendors 60 days on actively exploited vulnerabilities to 7 days before Google will release details.

============================================================NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM
Title: Google Shifts Policy, Will Release 0-days After A Week; Researcher Provides 0-day PoC
Description: In a major policy announcement made last week, Google
stated that it will publicly disclose details of new vulnerabilities in
other vendors' products 7 days after discovery, if those issues are
being actively exploited in the wild. This is a major shift from its
previous policy of giving vendors 60 days before disclosure. While
acknowledging that this new policy may be too short of a time frame for
vendors to develop a patch, Google stated that vendors should at least
make users aware of the situation and offer any possible mitigations
while a patch is being developed. Meanwhile, Google researcher Tavis
Ormandy has released exploit code for a local kernel vulnerability in
Windows ahead of a patch by Microsoft, after having released initial
details in mid-May. Microsoft claims that no active exploitation was
taking place prior to the release of the exploit code, although it is
likely that will change in the face of publicly available PoC.

Title: RFI Botnet Compromising WordPress, Joomla Sites Worldwide
Description: Researchers at the Deep End Research group released an
in-depth report this week on a major botnet that has been responsible
for compromising hundreds of thousands of WordPress and Joomla web sites
across the planet over the past year. The report, which is designed to
raise awareness among administrators of these notoriously vulnerable web
services, corresponds to attack techniques seen by Sourcefire since
September of 2011. System administrators are urged to check their
systems for signs of compromise by this botnet, and to ensure that their
systems have all of the latest available security patches and
recommended settings applied.

ClamAV: Trojan.Dapato-*
Title: Black Revolution DDoS Trojan In The Wild
Description: DDoS continues to be a favorite activity of attackers
worldwide, with recent attacks on financial institutions in particular
reaching 100+ Gbps levels. Researchers at Arbor Networks this week
profiled a particularly advanced DDoS trojan by the name of "Black
Revolution" they have been observing in the wild lately, with different
variants of the malware showing its creators' progress at evading
detection over time.

Title: German Torrent Contains Source For 309 Bots
Description: The authors of the well-respected "Malware Must Die" blog
this week published information on a huge dump of botnet source code
they discovered on a German torrent, which has since been shut down.
While most of the source is several years old, it provides valuable
insight into multiple important families of malware, including Zeus,
Skype-based bots, SDbot, and others. The source code is being shared
with security researchers, and should provide useful information for
network defenders worldwide.

This is a list of recent vulnerabilities for which exploits are available. System administrators can use this list to help in prioritization of their remediation activities. The Qualys Vulnerability Research Team compiles this information based on various exploit frameworks, exploit databases, exploit kits and monitoring of internet activity.
ID: CVE-2012-5946
Title: IBM SPSS SamplePower C1Tab ActiveX Heap Overflow
Vendor: IBM
Description: Buffer overflow in the c1sizer ActiveX control in
C1sizer.ocx in IBM SPSS SamplePower 3.0 before FP1 allows remote
attackers to execute arbitrary code via a long TabCaption string.
