New malicious application have been reported by Sophos that are targeting Facebook users, one thing that is not available on the social network platform is that users cannot check who have visited their profiles, this functionality can be found on LinkedIn and other similar websites.

The attack is spreading over Facebook message that invites user to follow a URL and install an application on FB profile, here you can find a copy of the message:

"New Update from facebook. Now you can check who visited your profile. check here -------->>>FAŒBOOK PROFILE VIEWER ®<<<<------
Who Watching your Profile ?"

By installing the application on your profile a fake webpage will be opened showing some contacts as they have been visiting your profile but this is not true and instead it post a public message to your friend about this fake application.

If you have been targeted by a similar app or you saw a friend posting about it try to be vigilant and send him a message to revoke the malicious application. Also it is important that he scan his system with updated security software and change his account password.
