Mystery Of NSA Leak Lingers As Stolen Document Case Winds Up

Federal agents descended on the suburban Maryland house with the flash and bang of a stun grenade, blocked off the street and spent hours questioning the homeowner about a theft of government documents that prosecutors would later describe as “breathtaking” in its scale.

The suspect, Harold Martin, was a contractor for the National Security Agency. His arrest followed news of a devastating disclosure of government hacking tools by a mysterious internet group calling itself the Shadow Brokers. It seemed to some that the United States might have found another Edward Snowden, who also had been a contractor for the agency.

“You’re a bad man. There’s no way around that,” one law enforcement official conducting the raid told Martin, court papers say. “You’re a bad man.” Later this month, about three years after that raid, the case against Martin is scheduled to be resolved in Baltimore’s federal court. But the identity of the Shadow Brokers, and whoever was responsible for a leak with extraordinary national security implications, will remain a public mystery even as the case concludes. Authorities have established that Martin walked off with thousands of pages of secret documents over a two-decade career in national security, most recently with the NSA, whose headquarters is about 15 miles from his home in Glen Burnie, Maryland. He pleaded guilty to a single count of willful retention of national defense information and faces a nine-year prison sentence under a plea deal.

Investigators found in his home and car detailed description of computer infrastructure and classified technical operations in a raid that took place two weeks after the Shadow Brokers surfaced online to advertise the sale of some of the NSA’s closely guarded hacking tools. Yet authorities have never publicly linked Martin or anyone else to the Shadow Brokers and the U.S. has not announced whether it suspects government insiders, Russian intelligence or someone else entirely.
