A malicious worm spreading through Skype instant messages threatens to take control of a victim's machine and hold its contents for ransom.
The issue, which was first brought to light Friday by
GFI, tricks users into downloading a ZIP file by displaying the socially-engineered message, "lol is this your new profile pic?" along with a link that also spreads the message to other Skype users. The ZIP filed contains an executable file that installs a variant of the Dorkbot worm and creating a backdoor via "Blackhole," an exploit kit used by criminals to infect computers through security holes.
