Matt Paul DeHart (born June 11, 1984) is an American citizen and former U.S. Air National Guard intelligence analyst and a registered sex offender.

[3] In September 2009, while monitoring the server, DeHart claims to have found an unencrypted folder containing hundreds of documents, including one detailing what looked like an FBI investigation into some particularly shady deeds by the CIA.

[14] DeHart claimed the "document dropped onto his Tor server included details of FBI's investigation into CIA's possible role in the anthrax attack".

[15][16] On August 18, 2010, DeHart signed consent forms (such as the permission for any FBI agent and "any Canadian law enforcement", to record his phone calls with his old military colleagues) and authorized agents to assume his online identity, giving the FBI his aliases, and passwords to his e-mail accounts.

[17] After an unsuccessful attempt to seek asylum in Canada, he was deported to the US on March 1, 2015, and handed over to FBI agents at the Peace Bridge border crossing.

[20] DeHart has claimed wrongful prosecution, accusing the U.S. government of using child pornography as a ruse to probe his activist activities.

[3] A victim-impact statement was delivered which accused DeHart of orchestrating a hoax in the media and in court to avoid taking responsibility for damaging lives.

[23] Although his conviction is in Tennessee, because his last known address was in Concord, New Hampshire, he was also required to register there as a sex offender, with a mugshot dated June 14, 2021.
