Viral clickjacking ‘Like’ worm hits Facebook users

Hundreds of thousands of Facebook users have fallen for a social-engineering trick which allowed a clickjacking worm to spread quickly over Facebook this holiday weekend.

Affected profiles can be identified by seeing that the Facebook user has apparently “liked” a link:

Messages seen being used by the spammers include:

"LOL This girl gets OWNED after a POLICE OFFICER reads her STATUS MESSAGE."

"This man takes a picture of himself EVERYDAY for 8 YEARS!!"

"The Prom Dress That Got This Girl Suspended From School."

"This Girl Has An Interesting Way Of Eating A Banana, Check It Out!"
