The Joint Threat Research Intelligence Group (JTRIG) is a unit of the Government Communications Headquarters (GCHQ), the British intelligence agency . The existence of JTRIG was revealed as part of the global surveillance disclosures by NBC News in documents leaked by the former National Security Agency contractor Edward Snowden.
The core self-identified purposes of JTRIG are to:
1. To inject all sorts of false material onto the internet in order to destroy the reputation of its targets.
2. To use social sciences and other techniques to manipulate online discourse and activism to generate outcomes it considers desirable.
The Intercept, a website organized by Glenn Greenwald, Laura Poitras, and Jeremy Scahill that reports on documents leaked by NSA whistleblower, Edward Snowden, has published some of these documents – including instructions on how to be an Internet troll for corporate purposes.
