U.S. indicts alleged copyright pirates; FBI hacked in retaliation WASHINGTON, Jan. 19 (UPI) -- Shortly after the U.S. Justice Department filed online piracy charges against megaupload.com and related sites, hackers said they took down the FBI's site. Efforts to access fbi.gov were unsuccessful Thursday evening. The hacker group Anonymous claimed via Twitter it had hacked into the FBI and record label sites in retaliation for the indictment against megaupload for alleged piracy of copyright material. The piracy allegedly generated $175 million in criminal proceeds and an estimated $500 million damage to copyright owners, Justice said in a release Thursday. Seven people and two corporations -- Megaupload Limited and Vestor Limited -- have been indicted on charges of engaging in a racketeering conspiracy, conspiring to commit copyright infringement and conspiring to commit money laundering. The indictment identified Kim Dotcom, aka Kim Schmitz, and Kim Tim Jim Vestor, 37, as the alleged head of the criminal operation.
