Attackers use Skype to spread Liftoh trojan

Users receiving shortened URLs in Skype instant messages, or similar IM platforms, should be wary of a new trojan, called Liftoh.

So far, it has primarily infected users in Latin America, said Rodrigo Calvo, a researcher at Symantec.

When targeted, victims receive a message in Spanish containing a shortened URL. The messages appear as if they are coming from someone on the user’s Skype contact list who is linking to a photo. If clicked, the link redirects users to 4shared.com, which is hosting a URL, which initiates a weaponized zip file containing Liftoh.
