The Dorkbot worm that fooled many a Facebook and Twitter user is now socially engineering Skype users into downloading the malware, whose payload now includes a mechanism to lock down machines. The latest iteration rummages through an infected Skype user s contact list and sends the message Lol is this your new profile pic? in English. It sends a similar message in German, too. Unzipping the file opens a backdoor and installs the worm. Victims are told, unless a $200 payment is made within 24 to 48 hours. Victims will be turned in to federal authorities.
