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

Top Vulnerability this week: CVE-2012-1875 in Internet Explorer: patched
as of June 12, but Microsoft alerted already in the original advisory
of targeted attacks against the vulnerability. Since then a Metasploit
module has been released that will make the exploit accessible to a much
larger attacker base.


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Compromised WordPress Blogs Used For Active Phishing Campaigns
Description: WordPress is a popular blogging platform written in PHP.
There are numerous security issues in the software, particularly in the
myriad of plug-ins available for the system maintained by third-party
groups. Several active phishing campaigns have been observed recently
using compromised WordPress installations to host exploit kits.

Snort SID: 21941, 23171

Title: CVE-2012-1889 Unpatched Microsoft XML Core Services Vulnerability
Description: A zero-day attack against the Microsoft XML Core Services
was released just after this month’s Patch Tuesday. Active exploitation
has been observed in the wild, including a Metasploit module that was
published on Friday, June 15. Users of Microsoft products, including
Internet Explorer and Office, are strongly urged to use Microsoft’s
Fix-It tool to mitigate the vulnerability pending a patch.

Title: AV Bypass For Malicious PDFs Using XDP
Description: A controversy over responsible disclosure has erupted over
an antivirus evasion technique demonstrated this past weekend by
security researcher Brandon Dixon. The technique uses the XDP
specification, which allows PDF files to be wrapped in XML, to bypass
file type checking and evade multiple antivirus vendors. Dixon
discovered the technique while analyzing a live sample from the field,
so exploits using it are clearly in use by malicious actors today.

Title: Fake Android Security App Is Zeus
Description: An Android application by the name of “Android Security
Suite Premium” has been linked to the Zeus malware family by researchers
at Kaspersky Labs. The malware includes functionality such as forwarding
all SMS messages received by the phone to a C&C server and other
information-stealing techniques. As this application was found outside
of the official Android market, users are encouraged to install
applications only from trusted sources.

Pack has been observed in active use in the wild recently. This kit was
used in a major attack on a Dutch web site in March, and has been
detected on other networks that Sourcefire monitors.
