The UKs spy agency launched a cyberattack against the hacker collectives Anonymous and LulzSec, according to documents leaked by former NSA contractor Edward Snowden and obtained by NBC News. The operations were carried out by the Joint Threat Research Intelligence Group (JTRIG), a division of the Government Communications Headquarters Communications (GCHQ), Britains NSA-equivalent. A PowerPoint presentation for a 2012 NSA conference reveals that JTRIG launched a distributed denial of service (DDoS) attack against the internet relay chat (IRC) rooms used by members of Anonymous. Some so-called hacktivists targeted the websites of the FBI, CIA, and GCHQ as part of Anonymous Operation Payback, staged in protest against the prosecution of Chelsea Manning.
