Technical Cyber Security Alert TA12-024A
"Anonymous" DDoS Activity
Original release date: January 24, 2012
Last revised: --
US-CERT has received information from multiple sources about coordinated distributed denial-of-service (DDoS) attacks with targets that included U.S. government agency and entertainment industry websites. The loosely affiliated collective "Anonymous" allegedly promoted the attacks in response to the shutdown of the file hosting site MegaUpload and in protest of proposed U.S. legislation concerning online trafficking in copyrighted intellectual property and counterfeit goods (Stop Online Piracy Act, or SOPA, and Preventing Real Online Threats to Economic Creativity and Theft of Intellectual Property Act, or PIPA).
Target selection, timing, and other attack activity is often coordinated through social media sites or online forums.
US-CERT is continuing research efforts and will provide additional data as it becomes available.
