Insecurity outfit Sophos said thousands of Farcebook users fell prey to an adware attack over the weekend, which promised a link to the "sexiest video ever".
The malicious posts, appeared to come from users' Farcebook friends, read: , this is without doubt the sexiest video ever! :P :P :P Candid Camera Prank [HQ] Length: 3:1
The messages were accompanied by what looked like a movie thumbnail of a woman on an exercise bicycle wearing a short skirt.
inevitably, the thumbnail doesn't play a video, but instead takes victims to a Facebook application that tells them they don't have the right player software installed, and tries to trick them into installing revenue-generating adware.
"You may want to watch a sexy video, but you're more likely to end up being plagued by pop-up advertising," warned Graham Cluley, senior technology consultant at Sophos. "Not only is adware being installed on your computer, but the rogue Facebook application is posting the same message to all of your friends' accounts. It's no surprise that your friends might click to watch the movie when it looks to all intents and purposes that you are the person who has sent it to them."
