A new worm spreading on Facebook via user’s walls. This worm uses what is technically known as a CSRF Cross-site Request Forgery, also called XSRF attack. A sequence of iframes on the exploit page call a sequence of other pages and scripts, eventually resulting in a form submission to Facebook “as if” the victim had submitted a URL for a wall post and clicked on the “Share” button to confirm the post.”
Such types of worms propagate on the Internet play by clicking upon a link to Want to see Something Hot or to simply install some application. With this the computer can become infected with these malware that often is very problematic and a pain in the backside to remove.
This attack seems to cause more awkwardness than it does damage to your computer or account, it is quite easy to fall for since all it requires is “clicking da button, baby.”
According to one of AVG blog, the worm spreads as users that are already logged into the social network click on the suggestive photo that is being placed on their walls by infected friends.
