Today, explicit hardcore porn images, photoshopped photos of celebrities such as Justin Bieber in sexual situations, pictures of extreme violence and even a photograph of an abused dog, have been distributed via Facebook - seemingly without the knowledge of users.
As the result of this attack, some facebook users plan to quit the account. They twitted in twitter.
It is unclear how the Explicit and Violent content has been spread in Facebook- whether users are falling for a Clickjacking attack,have poorly chosen privacy settings, have been tricked into installing malicious code, or have fallen victim to another vulnerability inside Facebook itself.
The attackers are upsetting many Facebook users and making the social networking site far from a family-friendly place.
One commenter to Naked Security, rxladyblue, told us:
"I just viewed a gay pornography pic that was on the news feed under her name. She could not see the pic but all of her friends could see it."
