Robert HanssenRobert Philip Hanssen (April 18, 1944 – June 5, 2023) was an American Federal Bureau of Investigation (FBI) agent who spied for Soviet and Russian intelligence services against the United States from 1979 to 2001. His espionage was described by the Department of Justice as "possibly the worst intelligence disaster in U.S. history". In 1979, three years after joining the FBI, Hanssen approached the Soviet Main Intelligence Directorate (GRU) to offer his services, beginning his first espionage cycle, lasting until 1981.
KGBThe Committee for State Security (CSS) (Komitet gosudarstvennoy bezopasnosti (KGB), kəmjɪˈtjet ɡəsʊˈdarstvjɪn(ː)əj bjɪzɐˈpasnəsjtjɪ) was the main security agency for the Soviet Union from 13 March 1954 until 3 December 1991. As a direct successor of preceding agencies such as the Cheka, GPU, OGPU, NKGB, NKVD and MGB, it was attached to the Council of Ministers. It was the chief government agency of "union-republican jurisdiction", carrying out internal security, foreign intelligence, counter-intelligence and secret police functions.
Double agentIn the field of counterintelligence, a double agent is an employee of a secret intelligence service for one country, whose primary purpose is to spy on a target organization of another country, but who is now spying on their own country's organization for the target organization. Double agentry may be practiced by spies of the target organization who infiltrate the controlling organization or may result from the turning (switching sides) of previously loyal agents of the controlling organization by the target.
Soviet espionage in the United StatesAs early as the 1920s, the Soviet Union, through its GRU, OGPU, NKVD, and KGB intelligence agencies, used Russian and foreign-born nationals (resident spies), as well as Communists of American origin, to perform espionage activities in the United States, forming various spy rings. Particularly during the 1940s, some of these espionage networks had contact with various U.S. government agencies. These Soviet espionage networks illegally transmitted confidential information to Moscow, such as information on the development of the atomic bomb (see atomic spies).
EspionageEspionage, spying, or intelligence gathering is the act of obtaining secret or confidential information (intelligence). A person who commits espionage is called an espionage agent or spy. Any individual or spy ring (a cooperating group of spies), in the service of a government, company, criminal organization, or independent operation, can commit espionage. The practice is clandestine, as it is by definition unwelcome. In some circumstances, it may be a legal tool of law enforcement and in others, it may be illegal and punishable by law.
DisinformationDisinformation is false information deliberately spread to deceive people. It should not be confused with misinformation, which is false information but is not deliberate. "Fake news" has sometimes been categorized as a type of disinformation, but scholars have advised not using these two terms interchangeably or using "fake news" altogether in academic writing since politicians have weaponized it to describe any unfavorable news coverage or information.
