U.S. identifies suspect in major leak of CIA hacking tools

The U.S. government has identified a suspect in the leak last year of a large portion of the CIA’s computer hacking arsenal, the cyber-tools the agency had used to conduct espionage operations overseas, according to interviews and public documents.

But despite months of investigation, prosecutors have been unable to bring charges against the man, who is a former CIA employee being held in a Manhattan jail on unrelated charges.
