Trojan Targets Skype Users

Miscreants have again adapted the Warezov Trojan horse to target Skype users, Websense Security Labs warned on Thursday.

The attack is similar to threats that target instant-messaging applications. A targeted Skype user will receive a chat message with the text "Check up this" and a link to a malicious executable called "file_01.exe" on a Web site, Websense said in an alert. If the user runs the file, several other files are downloaded and run, it said.

Once infected, a computer will be at the beck and call of the attacker and the Trojan horse will start sending messages to the victim's Skype contacts to propagate, Websense said. The attack is similar to one reported in February, but has been adapted with files hosted at different locations and a new version of the malicious code, it said.
