A spam campaign that poses as a virtual postcard delivery is being used to lure surfers into infecting their PCs with a Trojan horse.

Windows users who follow the web link in the junk emails are roped into visiting a website which exploits well known vulnerabilities to install the Clsldr-D Trojan horse and other malicious code onto vulnerable PCs. The malicious emails are being sent from a variety of domain names.

“There’s a very real risk that some people will think one of these emails is from a long forgotten friend or work colleague and follow the link out of curiosity,” said Graham Cluley, senior technology consultant for anti-virus firm Sophos. “If you receive an unexpected virtual postcard it may prove wise to simply delete it.”
