Waledac SMS Spy Theme - New Campaign ITW

Date:04.16.2009

Threat Type: Malicious Web Site / Malicious Code

Websense Security Labs™ ThreatSeeker™ Network has detected a new Waledac variant in the wild being distributed via email since yesterday.

The new campaign uses a theme whereby the user is enticed to download an application that will permit them to view other people's SMS messages online. The download file uses alternating filenames, including sms.exe, freetrial.exe, and smstrap.exe. ThreatSeeker has identified thousands of spam emails using this theme. 

Not all major antivirus vendors are currently detecting this threat according to this VirusTotal report.
