The National Security Agency (NSA) illegally used technology to spy on Megaupload founder Kim Dotcom, according to new documents from New Zealand's Government Communications Security Bureau (GCSB).
The New Zealand Herald first reported that the GCSB told the nation's high court that it ceased all surveillance of Dotcom in early 2012, but that "limited" amounts of communications from Dotcom were later intercepted by its technology without the bureau's knowledge.
Dotcom was surveilled by the NSA and the GCSB in a joint intelligence operation named Operation Debut. According to the Herald, that surveillance was scheduled to end in January 2012, but the United States continued to use New Zealand's technology.
