NEW YORK (AP) — A former CIA employee has pleaded not guilty to charges he was behind a damaging leak about the agency's secret hacking abilities.

Joshua Adam Schulte entered the plea on Wednesday in federal court in Manhattan.

Court papers accuse Schulte of stealing the classified information at the CIA's Virginia headquarters in 2016. Investigators suspect he then gave it to WikiLeaks.

Authorities say the so-called "Vault 7" leak revealed the agency's abilities to hack Apple and Android cellphones.

Around the time the material was made public last year, the FBI raided Schulte's apartment and seized multiple computers. He was later arrested and initially held on child pornography charges.

A new indictment earlier this week accuses the 29-year-old Schulte of violating the Espionage Act.
