At the time of the alleged incident, Snowden said he was working undercover for the CIA in Geneva maintaining computer network security. The CIA has declined to comment on Snowdens case, but the Swiss foreign ministry confirmed that he publicly held the position of an attaché with the permanent U.S. mission to the United Nations in Geneva from March 2007 to February 2009. A spokesperson for the U.S. State Department did not immediately respond to a request for comment for this report.

C.I.A. Warning on Snowden in 09 Said to Slip Through the Cracks

WASHINGTON Just as Edward J. Snowden was preparing to leave Geneva and a job as a C.I.A. technician in 2009, his supervisor wrote a derogatory report in his personnel file, noting a distinct change in the young mans behavior and work habits, as well as a troubling suspicion.
The C.I.A. suspected that Mr. Snowden was trying to break into classified computer files he was not authorized to access, and decided to send him home, according to two senior American officials.

It slipped through the cracks, one veteran law enforcement official said of the report.
