Have you logged on to your Facebook account and were greeted by graphic pictures in your wall? Don't panic because your friends did not decide on sharing their fetish with you. This is in fact, a case of spam taking over Facebook.

Facebook, the giant social networking sites announced that they were experiencing a deliberate spam attacks and this was behind the numerous graphic and violent images that was displayed in their news feeds. The spam's attack strategy for this is to entice users into copying and pasting a link or web address into their browser which would show a "cool" video or would tell users about the people who have viewed their profile. Instead of showing that supposed information, the Web site will install malicious software which would show violent and pornographic images like doctored images of celebrities like Justin Bieber or Miley Cyrus in their news feeds without their knowledge.

The spam attack started last week but this situation was already resolved based on the statement given by Frederic Wolens, a spokesman for Facebook. According to Wolens, the situation is now under control stating that "Our team responded quickly and we have eliminated most of the spam caused by this attack. Though the company denied disclosing the details about the number of people who were affected by the spam attack but they gave assurance that no user data or accounts were compromised due to the attack.

Some reports are speculating that the hackers behind the spam attack were the hacktivist group named "Anonymous". The speculation was based on decree declared by the said group back in August called the "Kill Facebook". The group plans to infect the "Fawkes virus" which was named after Guy Fawkes, the anti-hero in the movie V for Vendetta. The group even released a video which showcased the threat to Facebook.

The social networking giant believes that the reason for the spam attack is for financial gain due to its design. Once the user goes to the affiliate site, it could generate monetary revenue for the attackers. In response to this spam attack, Facebook mentioned its commitment to implore stricter security measures asserting that "We (Facebook) are now working to improve our systems to better defend against similar attacks in the future."
