Through a vulnerability called clickjacking and social engineering, a worm is spreading through the social network Facebook.According to what was said by the security company F-Secure, the worm displays the message: try not to laugh xD http://www.fbhole.com/omg/allow.php?s=a&r=[random number], which redirects to an error page and if the user clicks on this page a script will be generated that will try to send the same message thanks to an invisible iframe that chases the mouse pointer.
According to specialists this malware is not motivated by money, it seems to be just a mischief.
There is also another attack through the "like" option of Facebook. The messages that are used in these cases are: "LOL This girl, after a police officer read her status message", "This man took a picture of himself every day for 8 years!" and "This girl has an interesting way to eat a banana, You have to see!".
If an Internet user clicks on the "like" application the link takes him to a page with a message that says: Click here to continue, and immediately the same message will be published to all the friends of the first user.
