A recent blog post from Graham Cluley of Sophos has just highlighted the latest scam to hit Facebook, which encourages users to watch a shocking video of a teacher nearly killing a school boy.

If you've clicked on the link which says " Insanely Shocking Video" you'll be taken through a series of steps, whereby you'll end up being asked to input personal information.

If you have clicked through, in order to protect others and yourself you'll have to delete the link the app posts to your wall, as well as revoking the application's access to your profile (as detailed in the video) and you might want to warn you friends not to hit the link.

This is part of a spate of recent attacks on Facebook, as it again fails to protect its users by deleting the malicious application.

Tell us what you think. Should Facebook do more to protect users from this type of scam? Let us know in the comments below.
