Worm Uses Google to Squirm Around Facebook

A malicious program that sprang up on Facebook.com in late July has surfaced again, this time using Google's Web sites to sneak around security filters.On Tuesday, researchers at unified threat management vendor Fortinet noticed that a program similar to the Koobface worm had started using the Google Reader and Picasa Web sites to spread.

In the attack, criminals host images that look like YouTube videos on the Google sites in hopes of tricking victims into downloading malicious Trojan software.
