Secret policeSecret police (or political police) are police, intelligence, or security agencies that engage in covert operations against a government's political, religious, or social opponents and dissidents. Secret police organizations are characteristic of authoritarian and totalitarian regimes. They protect the political power of a dictator or regime and often operate outside the law to repress dissidents and weaken political opposition, frequently using violence. They may enjoy legal sanction to hold and charge suspects without ever identifying their organization.
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.
AbwehrThe Abwehr (German for resistance or defence, though the word usually means counterintelligence in a military context; ˈapveːɐ̯) was the German military-intelligence service for the Reichswehr and the Wehrmacht from 1920 to 1945. Although the 1919 Treaty of Versailles prohibited the Weimar Republic from establishing an intelligence organization of their own, they formed an espionage group in 1920 within the Ministry of Defence, calling it the Abwehr.
SMERSHSMERSH (СМЕРШ) was an umbrella organization for three independent counter-intelligence agencies in the Red Army formed in late 1942 or even earlier, but officially announced only on 14 April 1943. The name SMERSH was coined by Joseph Stalin. The formal justification for its creation was to subvert the attempts by Nazi German forces to infiltrate the Red Army on the Eastern Front.
Slánský trialThe Slánský trial (officially Proces s vedením protistátního spikleneckého centra v čele s Rudolfem Slánským English: "Trial of the Leadership of the Anti-State Conspiracy Centre Headed by Rudolf Slánský") was a 1952 antisemitic show trial against fourteen members of the Communist Party of Czechoslovakia (KSČ), including many high-ranking officials. Several charges, including high treason, were announced against the group on the grounds of allegedly conspiring against the Czechoslovak Republic.
Dead dropA dead drop or dead letter box is a method of espionage tradecraft used to pass items or information between two individuals (e.g., a case officer and an agent, or two agents) using a secret location. By avoiding direct meetings, individuals can maintain operational security. This method stands in contrast to the live drop, so-called because two persons meet to exchange items or information. Spies and their handlers have been known to perform dead drops using various techniques to hide items (such as money, secrets or instructions) and to signal that the drop has been made.
PolygraphA polygraph, often incorrectly referred to as a lie detector test, is a device or procedure that measures and records several physiological indicators such as blood pressure, pulse, respiration, and skin conductivity while a person is asked and answers a series of questions. The belief underpinning the use of the polygraph is that deceptive answers will produce physiological responses that can be differentiated from those associated with non-deceptive answers; however, there are no specific physiological reactions associated with lying, making it difficult to identify factors that separate those who are lying from those who are telling the truth.
AssassinationAssassination is the willful killing, by a sudden or secret attack, of a personespecially if prominent or important. It may be prompted by grievances, notoriety, financial, military, political or other motives. Many times governments, corporations, organized crime or their agents order assassinations. Acts of assassination have been performed since ancient times. A person who carries out an assassination is called an assassin or hitman.
Doctors' plotThe "doctors' plot" affair was a Soviet state-sponsored antisemitic campaign and conspiracy theory that alleged a cabal of prominent medical specialists (predominately of Jewish ethnicity) intended to murder leading government and party officials. It was also known as the case of saboteur doctors or killer doctors. In 1951–1953, a group of predominantly Jewish doctors from Moscow were accused of a conspiracy to assassinate Soviet leaders.
SabotageSabotage is a deliberate action aimed at weakening a polity, government, effort, or organization through subversion, obstruction, demoralization, destabilization, division, disruption, or destruction. One who engages in sabotage is a saboteur. Saboteurs typically try to conceal their identities because of the consequences of their actions and to avoid invoking legal and organizational requirements for addressing sabotage.
