In a recent revelation it has come to notice that, numerous Facebook users have gotten their computers infected with a worm, since they clicked on an image of a woman in provocative clothing. The users were redirected to a pornography website, after clicking on the image of woman.

The worm that infects such systems take upon itself to put up a Wall post on the users’ Facebook Wall with the image of a woman in swimwear and with the message “click ‘da button, baby.” The post is then visible on of the user’s profile, and can be viewed by friends, thus giving a boost to the worm cycle. The worm is sort of a recycling malware, that keeps infecting each and every computer through which the image of the woman has been clicked.

As per security experts, the worm could very well being used by its manufacturer to gain more referrals for the pornography website and in turn make money out of it. There is still no certain deduction to the manner in which the worm is operating, but many believe that the worm could be operating on the principles of cross-site request forgery attack (CSRF). In a CSRF attack, the hacker or the attacker make use of a user’s web credentials such as user name and password without the knowledge of the user and use it to post questionable material on other websites.

However, Facebook is currently categorizing this nuisance of a worm as click jacking, an unethical means of operation used by hackers and use specially designed programs to deceive the users and make them click on legitimate looking buttons and links. Commenting on the current situation, Facebook has stated,

“We’ve taken action to block the URL (Uniform Resource Locator) associated with this site, and we’re cleaning up the relatively few cases where it was posted. Overall, an extremely small percentage of users were affected.”
