Push "da button", Frank

"Some Facebook users have been infected with a worm after clicking on an image of a scantily clad woman, which then redirects the victims to a pornography site, according to security researchers.

"The worm posts an image on a victim's Facebook Wall with a photo of a woman in a bikini and the message `click 'da button, baby.` Wall posts are viewable by a Facebook user's friends.

"If a friend clicks on the image and is logged into Facebook, the image is then is posted to their own Wall. Their Web browser will then open a Web page with a larger version of the same image. A further click on "da button" redirects the friend to a pornography site, according to Roger Thompson chief research officer for antivirus vendor AVG Technologies. Thompson posted a video of the attack on his blog."
