Facebook has quickly become one of the most popular Social Networking websites around and that is something that virus writers, hackers and other bad guys have certainly noticed.
Now, there are reports of a virus called Koobface in circulation on Facebook. Here is how it works:
- A hacker infects a Facebook user’s PC
- The hacker then sends messages to the user’s Facebook friends. The messages say something like “You look just awesome in this new movie” or something seemingly innocent like that.
- A link contained in the message sends the recipient to a website where they are prompted to download a supposed update of Adobe’s Flash Player, so they can “view the video”.
- If the recipient clicks the link, their PC is infected and the cycle continues.
The hackers are taking advantage of the climate of trust the exists on Facebook. Friends feel that any message they receive from one of their friends on Facebook should be trusted because of the privacy features in place. We tend to let our guard down and not think that our friend’s account could have been hacked or that a message we receive could contain a malicous virus like Koobface.
