The CIA, in a document posted online Tuesday, said it has released new emails it says it obtained from former contractor Jeffrey Sterling, who left the agency in the fall of 2011.
Sterling was arrested in August for his role in a cyberattack that disrupted the private computer of an Arizona senator.
The documents obtained by Fox News were part of a batch of documents that the CIA said were released as part of an agreement with the FBI to release information that it did not previously have.
Sometime between September 2011 and December 2012, Sterling was paid $1.7 million for his work on the agency’s cyber defense project, which included the use of a computer network and a computer system to intercept and manipulate email messages.
Sometime between June 2012 and May 2013, Sterling and his company, Global Security Technologies, were paid $4.8 million for their work on a similar project, Global Impact, that was designed to identify and attack potential foreign adversaries.
Severing is being held at a federal prison in Georgia, where he was indicted on five counts of violating the Espionage Act.
He pleaded guilty last month to a single charge of wire fraud and is scheduled to be sentenced March 29.
The new emails show that Sterling and Global Impact co-founder Kevin Hall were paid more than $3 million each for their cyber defense work.
The emails also show that Global Impact paid Sterling to conduct reconnaissance on a number of targets including the U.S. House of Representatives, the State Department, and the United Nations.
The documents also show Sterling was charged with violating a cybersecurity contract by helping Global Impact obtain a password for the internal network of a U.N. employee in New York who was involved in the Iran nuclear deal.
