TOP VULNERABILITY THIS WEEK: The newly discovered W32/DistTrack malware

emerged as one of the most destructive pieces of malicious code in
years, spreading via SMB and intentionally killing machines within four
hours of infection. Although targeted at the energy sector for the time
being, any adaptation of this malware or code that emulated its behavior
could cause major disruptions for any company infected with it. Security
analysts and operations teams are urged to follow its progress closely
and deploy all available detection methods against it immediately.

NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: W32/DistTrack: destructive malware targeted against energy sector
Description: McAfee discovered last week an extremely destructive new
piece of malware that they dubbed DistTrack. Within four hours of
infection, the malware has not only overwritten critical system files
with a portion of a JPEG image, it overwrites the Master Boot Record
with zeroes and forces a reboot, effectively killing the machine, and
requiring users to use forensics tools to recover data. The Sourcefire
VRT has confirmed that this malware is in the wild, and is targeted
towards energy companies specifically. While attacks thus far have been
extremely targeted in nature, detection is very straightforward, and
users are urged to stay vigilant, as the consequences of a successful
attack would be devastating.

Title: SMSZombie Android trojan hits 500,000 users in China
Description: A major Android malware outbreak was spotted over the
weekend in China by security firm TrustGo. The malicious app, dubbed
SMSZombie, steals information from the impacted user and forwards it via
SMS to the creators of the malware; it also dials premium SMS numbers.
The malware is distinct from previous apps in that generates no TCP/IP
traffic to communicate with C&Cs, which hampers detection at the network
level. Signatures for downloads of the malicious files are available,
and mobile AV products should be used to spot and remediate infections
as appropriate.

Title: Briba trojan spreading by way of CVE-2012-1535
Description: Last week’s Flash 0-day attacks, which were patched by
Adobe as CVE-2012-1535, are continuing to spread in the wild. Live
command and control servers have been spotted by researchers around the
world, and targets outside of the initial military-industrial scope of
the 0-day attacks have been confirmed hit by the Sourcefire VRT. Users
are urged to patch their Flash installations to the most current release
immediately, as this attack is likely to continue spreading over time,
and will almost certainly make its way into exploit kits worldwide
within the next several weeks.

Title: Oracle FlashTunnelSvc Remote Code Execution
Description: Exploit code exists for a major, trivially exploitable
vulnerability against the Oracle FlashTunnelService. By hitting a
directory traversal bug and making use of the built-in writeToFile
function, users can drop arbitrary files on impacted systems, and then
call a URL in order to execute code in those files. The entire process
can be completed with no authentication. The Sourcefire VRT has observed
exploitation in the field, which can be fully automated with ease. Users
of Oracle systems are urged to patch immediately.
