Koobface Worm Targets Facebook Users

If you're on Facebook, be aware that a fast-spreading worm called Koobface is targeting users and trying to steal personal information such as credit card details. The Koobface worm sends a message to the Facebook user, supposedly from a friend, that says things like "you look funny in this new video" or "is it u there?" After clicking on the video link, the user is asked to download the latest version of Adobe Flash Player. Only after the user clicks on the fraudulent Flash update is the Koobface worm installed.

Take a look at an example of a Koobface message below:


This malware can then quickly seize credit card details in two ways - either by waiting for the user to buy something online and remembering the details, or by searching the computer for cookies from past online purchases.

With dozens of Koobface variants known to exist, security leader McAfee warns that the situation may get worse before it gets better. Should your PC be infected with the Koobface worm, Facebook suggests resetting your password and running updated antivirus software to purge the worm from your system.

It's important to note that Koobface attacked MySpace users before moving to Facebook, and has also jumped to the social networking site Bebo. All users of such sites would be well advised to stay alert for suspicious messages.
