February 2009 by Websense
Websense Security Labs™ ThreatSeeker™ Network has spotted an emerging malicious spam lure, mascerading to be from Skype.
The spammed message uses Skype’s logos and themes, posing as a Valentines promotion. With two days to go before Valentine’s day, the fake promotion entices to send a free valentines video message for a loved one. The proposed video link in the message leads to a malicious compressed archive file named valentine.exe located at http://[removed]ftp.com/skype.com/valentine/valentine.exe (SHA1: e5f752badaf0fbc0afcf3081ac10bf781da59de6).
Executing the file will install a version of Skype along with an IRC backdoor file named: spoolsv.exe
