In a rampage following the U.S. government’s takedown of file-sharing site MegaUpload, the hacktivist group Anonymous not only knocked the CBS.com website offline on Sunday, but deleted all its files.

As described by Gizmodo, “The CBS takedown wasn’t your regular DDoS attack because if you went to CBS.com at the time Anon attacked it, there was nothing except an index page with a single file. That’s it. Basically, Anonymous gained access to CBS.com and deleted EVERYTHING.”
