A US high school student has reportedly hacked the personal AOL account of CIA director John Brennan, uncovering a wide array of private data.

According to the hacker, who goes by the Twitter handle @phphax, everything from a "47-page application for top-secret security clearance" to details of the agency's "harsh interrogation techniques" were discovered in the breach, notes the New York Post.

Speaking with Infowars over encrypted communications, CWA, a seperate member of the "Crackas With Attitude" hacking group, briefly gave his thoughts on Brennan's online security practices.

"He's a loser," CWA said. "I hope he dies."
