The FBI is denying that it paid $1 million to Carnegie Mellon University to exploit a vulnerability in Tor.
"The allegation that we paid [Carnegie Mellon University] $1 million to hack into Tor is inaccurate," an FBI spokeswoman told Ars in a Friday morning phone call.
Two days ago, the head of the Tor Project accused the FBI of paying Carnegie Mellon computer security researchers at least $1 million to de-anonymize Tor users and reveal their IP addresses as part of a large criminal investigation.
