The case is causing leaders on Capitol Hill and in the Office of the Director of National Intelligence to re-examine exactly how the government defends against insider threats.

A federal grand jury returned an indictment Wednesday accusing former defense contractor Harold T. Martin III of stealing classified and top secret government documents.

Harold Martin reportedly compromised more than 75 percent of hacking tools that were stored in a secretive library used by the agency’s elite hacking unit.

The man arrested by the FBI in connection with elite hacking tools being publicly leaked was found with a massive library of government data, had multiple unregistered firearms in his possession and was found to be communicating online with various individuals in Russian.
