TOP VULNERABILITY THIS WEEK: A potentially state-sponsored, targeted

banking trojan platform named Gauss was discovered by Kaspersky Labs
late last week. The payload of this malware has yet to be decoded,
though C&C servers around the world have been sinkholed to prevent
further damage. While limited in scope, comparisons to Flame have people
around the world concerned.


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Gauss Malware Platform Discovered in Lebanon
Description: Kaspersky Labs published a report late last week about a
new malware platform they’ve dubbed Gauss, which targets users in
Lebanon and other parts of the Middle East and attempts to steal
credentials for a variety of instant messaging, email, social
networking, and banking systems. Gauss was similar to Flame in many
ways, and as such is being attributed to nation-state actors. On
Tuesday, Kaspersky appealed to cryptographers worldwide for help in
decrypting its payload, which could prove very interesting if it
contains links to SCADA systems or other Flame-related targets.

ClamAV: W32.Trojan.Gauss-[1-15]

Title: FinFisher Lawful Intercept Malware Used Outside of Law Enforcement
Description: German company Gamma International produces surveillance
software named FinFisher, and has targeted it to governments and law
enforcement for lawful intercept purposes. The software recently
appeared in phishing attacks against activists in Bahrain, despite
ardent claims by its manufacturer that it had not been sold there. While
the scope of the attack is limited, it sets a disturbing precedent of
powerful surveillance software falling into the wrong hands.

ClamAV: Trojan.FinFisher

Title: Non-Alphanumeric JavaScript Packer
Description: A tool was recently released to encode JavaScript using
only the following characters: “()[]{}!+”. While it has yet to be
observed in the wild, advances in JavaScript evasion technologies
invariably find their way into the hands of malicious actors, and there
is no reason that this tool or a variation thereof will be an exception.
The Sourcefire VRT will be closely monitoring samples of obfuscated
JavaScript in the wild, looking for signs that this technique is being
incorporated into exploit kits or the like.

Snort SIDs: 23831, 23832
ClamAV: N/A

Title: Microsoft Windows Common Control Tabstrip ActiveX Remote Code Execution
Description: A memory corruption vulnerability exists in the Microsoft
Windows Tabstrip ActiveX control, which is part of the Windows Common
Control set (and is thus built into Windows by default). According to
Microsoft, targeted attacks have been observed in the wild, though to
date no exploit code or proof-of-concept has been made public. As
ActiveX vulnerabilities are typically very straightforward to exploit,
extensive exploitation in the field is likely in the near term.
