Former National Security Agency contractor Harold Martin allegedly stole documents that seem far more sensitive than what has come from the Snowden leaks.

For more than two decades, Martin allegedly made off with highly-classified documents that were found in his home and car that included discussions of the US military’s capabilities and gaps in cyberspace, specific targets, and “extremely sensitive” operations against terror groups, according to an indictment released Wednesday.

Martin was arrested by the FBI at his home on August 27, 2016. Agents found thousands of pages and “many terabytes of information” there, according to court documents reviewed by The New York Times.

With the release of the indictment, it has become more clear of what was apparently in those files.
