According to this CNET post the FBI remotely installed spyware on a MySpace account suspected of being used by a bomb threat hoaxster. The software was designed to phone home with the IP address of the suspects computer and other information garnered from the PC. The suspect was a former student of the High School that was subject of the threats. The FBI had reported in 2001 that it was working on such software, a virus called Magic Lantern, but hasn't said much about it since. I wonder if MySpace cooperated in this case or if it was done totally cloak and dagger?
