NSA’s alleged leaker got tripped up by a secret printer feature

The Department of Justice is charging Reality Winner with leaking a classified NSA report — investigators just had to follow the hidden prints. 

Investigators rely on all kinds of prints to find suspects — fingerprints, footprints and, in Reality Winner’s arrest, invisible prints.

On Monday, the National Security Agency contractor was charged in a Georgia court with releasing classified material to a news outlet. The top-secret information was an NSA report from May 5, which was first released to The Intercept, detailing Russian hackers trying to compromise US officials less than two weeks before Election Day in November.
