These fingerprints are loaded into NSA database systems like XKeyscore, a bespoke collection and analysis tool that NSA boasts allows its analysts to see “almost everything” a target does on the Internet. The NSA creates “fingerprints” that detect HTTP requests from the Tor network to particular servers. This is done via the agency’s partnership with US telecoms firms under programs codenamed Stormbrew, Fairview, Oakstar and Blarney. To accomplish this, the NSA relies on its vast capability to monitor large parts of the Internet. The first step of this process is finding Tor users. ![]() ![]() ![]() The NSA refers to these capabilities as CNE, or computer network exploitation. The trick identifies Tor users on the Internet and then executes an attack against their Firefox web browser. The majority of NSA employees work in SID, which is tasked with collecting data from communications systems around the world.Īccording to a top-secret NSA presentation provided by the whistleblower Edward Snowden, one successful technique the NSA has developed involves exploiting the Tor browser bundle, a collection of programs designed to make it easy for people to install and use the software. The work of attacking Tor is done by the NSA‘s application vulnerabilities branch, which is part of the systems intelligence directorate, or SID.
