Just over a month after reports of a malware attack on the anonymous Tor network, the FBI told an Irish court that it was behind the shenanigans. But don't worry, it was for a good cause.
The Tor hack was supposed to target associates of the Freedom Hosting's operator Eric Eoin Marques who's currently being detained in Dublin, Ireland for his involvement in a massive child pornography operation. Freedom Hosting has indeed been under suspicion of allowing kiddie porn on its servers for some time now, but the investigation took a turn for the technical when the Feds exploited a loophole the version of Firefox that forms the basis for the Tor Browser Bundle.
The fun thing about this case, as with all of the NSA hacking business, is that the actions appear to be totally legal. It's just another case of a spying agency doing what it was designed to do: spy. Any of the innocent Tor users who were exposed along the way, well, too bad for them. That's America, where they have a right to privacy. Except for when the government says they don't.
