Multiple branches of the U.S. military have bought access to a powerful internet monitoring tool that claims to cover over 90 percent of the world’s internet traffic, and which in some cases provides access to peoples’ email data, browsing history, and other information such as their sensitive internet cookies, according to contracting data and other documents reviewed by Motherboard. 

Additionally, Senator Ron Wyden says that a whistleblower has contacted his office concerning the alleged warrantless use and purchase of this data by NCIS, a civilian law enforcement agency which is part of the Navy, after filing a complaint through the official reporting process with the Department of Defense, according to a copy of the letter shared by Wyden’s office with Motherboard.
