The Soviet Union and the KGB
The Soviet Union and its security service, the KGB, ran espionage, assassination, and disinformation across the Cold War and left a set of enduring mysteries behind the Iron Curtain. Successor Russian services carry some of these stories into the present. These files involve the USSR, the KGB, or their modern heirs as central actors.

The Cambridge Five: British establishment insiders secretly spied for the Soviet Union
The Cambridge Five is the rare 'conspiracy' that is entirely real and fully documented. In the 1930s Soviet intelligence recruited a group of idealistic, well-connected young men at Cambridge University (Kim Philby, Donald Maclean, Guy Burgess, Anthony Blunt, and John Cairncross) and steered them into the heart of the British establishment: the Foreign Office, MI5, MI6, Bletchley Park, and the wartime atomic project. For roughly twenty years they handed Moscow a torrent of secret material, including diplomatic traffic, intelligence on British and American operations, code-breaking work, and early information on the Anglo-American atomic bomb programme. Maclean and Burgess bolted to Moscow in 1951; Philby followed in 1963; Blunt confessed secretly in 1964 and was exposed to the public by Prime Minister Margaret Thatcher in 1979; Cairncross was eventually confirmed as the 'fifth man'. This case file sets out that record, anchored in the men's confessions and the MI5 files declassified at the UK National Archives, and marks the genuine questions that historians still argue over.
Read the case file →The Soviet NKVD murdered roughly 22,000 Polish officers and citizens at Katyn in 1940, then blamed Nazi Germany and covered it up for half a century
Katyn is the rare conspiracy that turned out to be exactly what its accusers said: a mass murder by one government, pinned on another, and buried by both sides of an alliance for reasons of state. In the spring of 1940 the Soviet NKVD executed roughly 22,000 Polish army officers, police, and members of the intelligentsia on a written order signed by Stalin and five other Politburo members. When Nazi Germany uncovered the graves in 1943 and correctly blamed the Soviets, Moscow accused the Germans instead and manufactured a false investigation to prove it. Poland's Western allies, needing the USSR to win the war, looked away; the United States shelved intelligence from its own officers that pointed to Soviet guilt. The truth was established in stages: a 1952 congressional investigation, the Soviet admission of 1990, the Russian parliament's acknowledgment in 2010, and US documents declassified in 2012. This case file lays out that record and separates what is settled from the narrower points still argued.
Read the case file →Bulgarian dissident Georgi Markov was assassinated in London in 1978 with a ricin pellet fired from a modified umbrella, on the orders of the Bulgarian secret service with KGB help
On 7 September 1978, Georgi Markov, a 49-year-old Bulgarian writer and broadcaster who had defected in 1969 and gone on to ridicule the Sofia regime on the airwaves of the BBC World Service, Radio Free Europe, and Deutsche Welle, was waiting for a bus on Waterloo Bridge in London when he felt a sharp sting in the back of his right thigh. He turned to see a man picking up a dropped umbrella, who murmured an apology and left by taxi. Markov fell ill with a high fever and died four days later. A postmortem recovered a pinhead-sized platinum-iridium pellet drilled with two tiny cavities that had held ricin, a poison for which there is no antidote. A coroner ruled that he had been unlawfully killed. This case file separates the record (a poisoning ruled an unlawful killing) from the claim it rates (that the Bulgarian secret service, aided by the KGB, was responsible), which is the accepted historical account and is rated substantiated, with the genuine loose ends noted.
Read the case file →Korean Air Lines Flight 007 was shot down by a Soviet interceptor in 1983 after straying into Soviet airspace, an event that spawned enduring but unsupported theories that the airliner was a deliberate spy mission and that its passengers survived
In the early hours of 1 September 1983, Korean Air Lines Flight 007, a Boeing 747 flying from New York to Seoul by way of Anchorage, drifted far off its planned route and crossed into Soviet airspace over the Kamchatka Peninsula and Sakhalin Island. A Soviet Su-15 interceptor shot it down over the Sea of Japan, killing all 269 passengers and crew, among them a sitting United States congressman. The shootdown became one of the sharpest flashpoints of the late Cold War. It also became a magnet for theories: that the airliner had been on a deliberate spying mission, that the Soviets knew it was a spy plane, and that the passengers survived and were spirited into Soviet camps. This file keeps the documented shootdown, established by the ICAO investigation and the recovered flight recorders, separate from that conspiracy layer, which the evidence does not support.
Read the case file →A foreign adversary attacked US personnel with a secret energy weapon and the government is hiding it
Beginning in late 2016, US diplomats and intelligence officers in Havana reported a frightening set of symptoms: a sudden sensation of pressure or piercing sound, followed by headaches, dizziness, ringing ears, and lasting cognitive problems. More than 1,000 of these 'anomalous health incidents' have since been reported worldwide. This case file separates two things that are often merged. The symptoms are real, sometimes disabling, and deserve to be taken seriously. The specific conspiracy claim, that a foreign adversary struck personnel with a secret microwave or directed-energy weapon and that the US government is concealing the true cause, is the claim rated here, and on the current record it is unproven: the March 2023 Intelligence Community assessment found a foreign adversary 'very unlikely', while a 2020 National Academies report and a number of unexplained cases keep the medical question genuinely open.
Read the case file →Indian prime minister Lal Bahadur Shastri's sudden death in Tashkent in 1966, officially a heart attack, was suspected by many to be a poisoning, a suspicion kept alive by an absent autopsy and by the state's continuing refusal to open its file
Lal Bahadur Shastri, the second prime minister of India, died in Tashkent, then in the Soviet Union, in the early hours of 11 January 1966, only hours after he and Pakistan's president Ayub Khan signed the Tashkent Declaration ending the 1965 war between their countries. The official cause was a heart attack. Because his death was ruled natural, no post-mortem examination was carried out, in Tashkent or after his body was flown home. That absence, together with family accounts of a discolored body and later reports of unexplained marks, seeded a durable suspicion that Shastri was poisoned. Decades of requests to see the government's records have met with refusal: the Prime Minister's Office has said it holds a single classified file on the death and will not release it, and the Central Information Commission has pushed back. This file separates the documented event from the unproven poisoning theory and reports the doubt as a product of secrecy and the missing autopsy.
Read the case file →The 2022 Nord Stream pipeline blasts were a covert state sabotage operation whose real perpetrator is being concealed
In the early hours of 26 September 2022, underwater explosions tore open the Nord Stream 1 and Nord Stream 2 gas pipelines beneath the Baltic Sea near the Danish island of Bornholm. Seismographs recorded the blasts, gas boiled to the surface for days, and investigators from three countries found residue of explosives. That it was deliberate sabotage is established. Who ordered it is not. The vacuum filled quickly with rival state-actor theories: a pro-Ukrainian operation, a Russian false flag, a covert US strike. This case file keeps the settled fact (sabotage) apart from the contested claim (attribution plus an alleged cover-up), and weighs what each official investigation actually found.

A shortwave station on 4625 kHz has broadcast a monotonous, roughly-once-every-few-seconds buzz for more than forty years, occasionally breaking off for a short coded message in Russian. No state has ever admitted running it. It is widely presumed to be a Russian military command channel; just as widely, and far less securely, rumored to be a nuclear doomsday system.
Read the case file →The Dyatlov Pass hikers were killed in a military or paranormal cover-up
Nine experienced hikers died in the Ural Mountains in February 1959, their tent slashed open from inside and their bodies scattered with injuries the original inquest called the result of an 'unknown compelling force.' Six decades of secrecy and strangeness later, a 2021 avalanche study offers the most complete natural explanation yet, without quite closing the file.
Read the case file →The 'Doctors' plot,' the 1953 charge that mostly Jewish Soviet physicians conspired to murder Soviet leaders for Western intelligence and 'Jewish nationalists,' was an antisemitic frame-up fabricated by Stalin's regime
The 'Doctors' plot' (Delo vrachey, the 'Doctors' case') was an antisemitic conspiracy manufactured by Stalin's regime in its final months. On 13 January 1953 Soviet newspapers announced that a ring of eminent Kremlin physicians, most of them Jewish, had been arrested for plotting to murder Soviet leaders as agents of Western intelligence and of the American Jewish Joint Distribution Committee, cast as a 'Jewish bourgeois-nationalist organization.' None of it was true. The doctors were innocent, the charges were fabricated, and the 'confessions' were extracted by torture. The case was the culmination of the postwar 'anti-cosmopolitan' campaign that had already produced the 1948 murder of the actor Solomon Mikhoels and the dissolution of the Jewish Anti-Fascist Committee, and it unleashed a wave of state antisemitism: dismissals, denunciations, and widespread fear among Soviet Jews of a mass deportation. It collapsed almost as fast as it began. After Stalin died on 5 March 1953, the new leadership declared the charges fabricated, released the survivors, and on 4 April 1953 Pravda announced the doctors had been rehabilitated. This file reports the frame-up as what it was; its target is the fabrication, never the people it maligned.
Read the case file →The claim that the 1932–1933 Holodomor famine in Soviet Ukraine did not happen, was a purely natural crop failure, or carried no state responsibility is a debunked denial, contradicted by Soviet policy records, opened archives, and the historians' consensus that the famine was man-made
In 1932 and 1933 a catastrophic famine swept Soviet Ukraine and other grain-growing regions of the USSR, killing an estimated 3.5 to 5 million Ukrainians. It did not fall from the sky. It followed forced collectivization, punishing grain-requisition quotas that stripped villages of food, the blacklisting of communities that failed to meet those quotas, and a January 1933 order that sealed Ukraine's borders so starving peasants could not flee to find bread. Moscow suppressed the news, banned the word famine, and was assisted abroad by correspondents like Walter Duranty, who told readers there was no starvation, while the Welsh journalist Gareth Jones reported the truth and was denounced for it. Since then, denial has passed from Soviet propaganda to modern Russian minimization. This file centers the documented policies and the archival and eyewitness record, and reports the denialist claims solely in order to refute them. It also treats honestly the live scholarly question of whether the Holodomor legally constitutes genocide, which is a debate about a legal label, not about whether the famine happened.
