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.

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.

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.

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.

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.
