This 18 April 2012 post from the NSA internal newsletter SSO Weekly reveals that AT&T (FAIRVIEW) cooperated with the NSA, under the terms of a FISA court order, to enable the agency to surveil the internet traffic going to and from the United Nations headquarters in New York: see the New York Times article AT&T Helped U.S. Spy on Internet on a Vast Scale, 15 August 2015.
This 26 April 2011 SIDToday post from the NSA/CSS Threat Operations Center (NTOC) Hawaii describes how the NSA has developed its capabilities in collecting “other people’s sigint”, for instance in exploiting Chinese operations against the United Nations: see the Der Spiegel article The Digital Arms Race: NSA Preps America for Future Battle, 17 January 2015.
Navi Pillay, the United Nations High Commissioner for Human Rights, has suggested the United States should drop its prosecution of Edward Snowden, because his revelations have served the public and launched an international debate about electronic surveillance. Earlier this year, the United States unsealed a criminal complaint against Snowden that includes multiple Espionage Act counts, each of which carries a ten-year prison sentence.
Speaking at the launch of a report into surveillance commissioned by the UN General Assembly as a direct consequence of Edward Snowden’s revelations, Pillay said that “those who disclose human rights violations should be protected, we need them.”
This document lists the 193 governments, intragovernmental organisations and other entities which the NSA was granted the legal authority to intercept communications “about” for foreign intelligence purposes in August 2010: see the Washington Post article Court gave NSA broad leeway in surveillance, 30 June 2014.
