It's happened to us, and it's probably happened to you if you use Facebook. You click on the news feed to see what others are posting and there it is; a graphic image of pornography.
Although none of the news networks or the Associated Press are reporting it yet, several other news organizations are aware of it. The Christian Post, Gawker, The Examiner, and AVN are all reporting hackers have invaded Facebook with a virus that has plastered porn all over.
From the Christian Post:
The hacks do not seem to have specific targets but happen at random with some user’s newsfeeds being littered with objectionable content and others not seeing anything.
Some of the hacks happen in the form of "click' spam being sent out. A popular spam involves Kim Kardashian with a link to a video. It will say something like "After watching this video I lost all respect for Kim." Upon clicking, the link takes the unsuspecting person nowhere, and hacks the account sending the same spam to all of the user’s friends.
