Facebook has reportedly been hit by a cyber attack that posted hardcore pornography and sickening scenes of violence on users profiles.
A virus, which appears to target the new 'timeline' feature has surged across the social network by luring users into clicking on to it with images of celebrities, then flooding their personal accounts with sex and violent scenes.
There have been suggestions that notorious hacker group Anonymous is behind the attack, as it earlier vowed to 'destroy' Facebook on November 5, but no one has come forward to claim it, the Daily Mail reports.
This new torrent of imagery has lead to many users deactivating their accounts to stop family and friends being subjected to the graphic imagery.
There is growing anger towards the social network as it is apparently unable to stop the material despite strict controls of what can be posted on the site, the paper said.
Meanwhile, a Facebook spokesperson said the company is investigating and addressing the issue.
"Protecting the people who use Facebook from spam and malicious content is a top priority for us and we are always working to improve our systems to isolate and remove material that violates our terms," the spokesperson said.
