A secret operation, code-named "MINARET", was set up by the NSA to monitor the phone communications of Senators Frank Church and Howard Baker, as well as major civil rights leaders, including Martin Luther King, Jr., and prominent U. journalists and athletes who criticized the Vietnam War. The NESTOR family of compatible secure voice systems it developed was widely deployed during the Vietnam War, with about 30,000 NESTOR sets produced. revealed that the NSA, in collaboration with Britain's SIGINT intelligence agency Government Communications Headquarters (GCHQ), had routinely intercepted the international communications of prominent anti-Vietnam war leaders such as Jane Fonda and Dr. In 1986, the NSA intercepted the communications of the Libyan government during the immediate aftermath of the Berlin discotheque bombing.
The NSA mounted a major effort to secure tactical communications among U. However a variety of technical and operational problems limited their use, allowing the North Vietnamese to exploit and intercept U. The White House asserted that the NSA interception had provided "irrefutable" evidence that Libya was behind the bombing, which U. President Ronald Reagan cited as a justification for the 1986 United States bombing of Libya.
Soon, these companies publicly discontinued their collaboration. Stimson, who defended his decision by stating, "Gentlemen do not read each other's mail".
Despite the Chamber's initial successes, it was shut down in 1929 by U. However, the AFSA was unable to centralize communications intelligence and failed to coordinate with civilian agencies that shared its interests such as the Department of State, Central Intelligence Agency (CIA) and the Federal Bureau of Investigation (FBI). Truman ordered a panel to investigate how AFSA had failed to achieve its goals.
The massive extent of the NSA's spying, both foreign and domestic, was revealed to the public in a series of detailed disclosures of internal NSA documents beginning in June 2013.Internationally, research has pointed to the NSA's ability to surveil the domestic Internet traffic of foreign countries through "boomerang routing". A code and cipher decryption unit was established as the Cable and Telegraph Section which was also known as the Cipher Bureau. During the course of the war it was relocated in the army's organizational chart several times. It absorbed the navy's Cryptanalysis functions in July 1918. Army cryptographic section of military intelligence, known as MI-8, in 1919, the U. government created the Cipher Bureau, also known as Black Chamber.The origins of the National Security Agency can be traced back to April 28, 1917, three weeks after the U. World War I ended on November 11, 1918, and the army cryptographic section of Military Intelligence (MI-8) moved to New York City on May 20, 1919, where it continued intelligence activities as the Code Compilation Company under the direction of Yardley. The Black Chamber was the United States' first peacetime cryptanalytic organization.On January 24, 2000, NSA headquarters suffered a total network outage for three days caused by an overloaded network.Incoming traffic was successfully stored on agency servers, but it could not be directed and processed.In the aftermath of the September 11 attacks, the NSA created new IT systems to deal with the flood of information from new technologies like the Internet and cellphones.
