The U.S. Department of Justice said Andrew Otto Boggs and Justin Gray Liverman were part of the “Crackas With Attitude” group blamed for the attacks.

Email accounts of the CIA's director, the chief of National Intelligence and many others, were hit by the group. It also stole and published details of 29,000 FBI and Homeland Security agents and workers.

As Ars Tec noted, according to prosecutors, at least three other suspected members located in the UK are under investigation by that country's Crown Prosecution Service.
