Ars Technica: A new clickjacking scheme is rapidly spreading pornographic and violent images across Facebook. Users who click on some news links are reporting that the disturbing images have been posted to their profile pages and newsfeeds without their permission.
Although Anonymous has not claimed responsibility for the attacks, some security researchers say the hacktivist group may be behind the scheme. Anonymous had threatened attacks of Facebook on Guy Fawkes day (Nov. 5).
Facebook says it is investigating the problem.
