XKeyscore is a global NSA analytic system that allows analysts to search across vast repositories of intercepted internet content and metadata by selector — email address, phone number, IP address, or keyword. Revealed by the Guardian in July 2013 using Snowden training documents, XKeyscore was described in NSA materials as the agency's 'widest-reaching' signals intelligence analytic tool. Analysts could query billions of records covering email, chat, browsing history, and search queries without prior court approval for individual searches.

Revealed in September 2013 by a joint ProPublica, New York Times, and Guardian investigation using Snowden documents, Bullrun was a classified NSA programme to covertly undermine encryption standards, introduce backdoors into commercial products, and work with or coerce technology companies to weaken their cryptographic implementations. The most specific confirmed element was the NSA's role in promoting Dual_EC_DRBG as an NIST standard with a likely built-in backdoor. A December 2013 Reuters report revealed that RSA Security had received $10 million from the NSA to make Dual_EC the default random number generator in its BSAFE toolkit.

President Bush secretly authorised the NSA to conduct warrantless surveillance of Americans' international communications beginning in October 2001, in a programme codenamed Stellar Wind. The programme bypassed the Foreign Intelligence Surveillance Court. A 2004 Department of Justice revolt — dramatised by the Comey/Ashcroft hospital confrontation — nearly ended it. The New York Times revealed the programme in December 2005 after sitting on the story for a year. Stellar Wind is confirmed by declassified NSA documents, congressional testimony, and multiple Inspector General reports.

The MUSCULAR programme, revealed by the Washington Post in October 2013 based on Snowden documents, showed that the NSA and GCHQ had secretly tapped the unencrypted fibre-optic links connecting Google's and Yahoo's data centres to one another. Unlike PRISM, which used legal orders to compel disclosure, MUSCULAR accessed data in transit on private backbone infrastructure without the companies' knowledge. The disclosure prompted both companies to encrypt their internal links. MUSCULAR is confirmed by NSA slides published by the Washington Post.

The Phoenix Program (Phung Hoang) was a joint CIA-South Vietnamese intelligence operation running from roughly 1965 to 1972, targeting the Viet Cong Infrastructure (VCI) through capture, interrogation, defection, and killing. CIA Director William Colby testified before Congress in 1971, confirming approximately 20,587 VCI kills through July 1971; South Vietnamese figures put the overall total at 40,994 by the programme's end. Declassified records confirm systematic extrajudicial killing and torture. The programme is a confirmed historical operation, not a conspiracy theory — its scale and methods were obscured from the public during the war, fitting the definition of a concealed government operation.

In June 1998, CNN's NewsStand programme broadcast a report claiming that US Special Forces used sarin nerve agent during Operation Tailwind in Laos in September 1970, specifically to kill American defectors. CNN retracted the report in July 1998 after an independent review by First Amendment attorney Floyd Abrams found the claim was not supported by the evidence gathered. The two producers responsible were dismissed. Operation Tailwind itself was a real classified SOG mission; the sarin-on-defectors claim is the fabricated element, retracted by the news organisation that aired it.

Operation Ranch Hand was the US Air Force aerial herbicide spraying programme in South Vietnam from 1962 to 1971. Approximately 19 million gallons of herbicides — including Agent Orange, which contained dioxin (TCDD) as a manufacturing byproduct — were sprayed over approximately 4.5 million acres. Internal documents from Dow Chemical and Monsanto, the primary suppliers, show that both companies were aware of the toxicity of dioxin contamination in their products before and during production. The US government did not publicly acknowledge health risks to veterans until the late 1970s and did not establish presumptive service connection for Agent Orange-related diseases until 1991. The concealment of known dioxin risks is confirmed by the documentary record.

The Gulf of Tonkin incident comprises two alleged North Vietnamese torpedo attacks on US destroyers USS Maddox and USS Turner Joy in the Gulf of Tonkin in August 1964. The first attack, on 2 August 1964, occurred and is documented. The second alleged attack, on 4 August 1964, did not occur. A 2005 NSA declassified historical study by analyst Robert Hanyok concluded that signals intelligence had been selectively reported to produce a false picture of a second attack that never happened. The Johnson administration used both incidents to secure the Gulf of Tonkin Resolution, providing the legal basis for the Vietnam War. The fabrication of the second attack is confirmed by declassified intelligence records.

The Lavon Affair (also called Operation Susannah) was a failed Israeli covert operation in 1954 in which Egyptian-Jewish agents recruited by Israeli military intelligence carried out a series of bombings against British and American targets in Cairo and Alexandria. The operation was designed to be attributed to the Muslim Brotherhood or Egyptian communists, with the aim of destabilising the relationship between Egypt and the Western powers and discrediting the Nasser government. The network was exposed by Egyptian security services; Israeli defence minister Pinhas Lavon resigned over the affair in 1955. Israel officially acknowledged the operation in 2005.

Operation Gladio was a NATO-coordinated programme of clandestine "stay-behind" networks established across Western Europe from the late 1940s, designed to conduct sabotage and resistance operations in the event of a Soviet invasion. The networks were armed, trained, and funded by CIA and MI6 and operated in coordination with national intelligence services. Italian Prime Minister Giulio Andreotti disclosed the Italian network to parliament in August 1990. The Italian parliamentary commission and subsequent national investigations in Belgium, France, Germany, and Switzerland confirmed the programme's existence across the continent.

Operation Mockingbird was a large-scale CIA programme begun in the late 1940s that recruited journalists, editors, and news executives to plant stories, shape narratives, and advance US foreign-policy objectives through ostensibly independent media outlets. The programme was exposed by the Church Committee investigations of 1975-76 and confirmed in detail by Carl Bernstein's October 1977 Rolling Stone exposé, which named over 400 US journalists and media organisations as having worked with the CIA. The programme is confirmed by declassified documents and congressional testimony.

Project Azorian was a classified CIA operation in which the purpose-built ship Hughes Glomar Explorer raised portions of the sunken Soviet ballistic-missile submarine K-129 from a depth of approximately 16,500 feet in the Pacific Ocean in 1974. The project used a Howard Hughes cover story — ostensibly a deep-sea mining vessel — to conceal the operation. It was partially declassified in 2010. The operation is fully confirmed and represents one of the most technically ambitious covert operations in history.

GlaxoSmithKline's diabetes drug Avandia (rosiglitazone) was approved by the FDA in 1999. A 2007 meta-analysis by cardiologist Steven Nissen, published in the New England Journal of Medicine, found that Avandia was associated with a 43% increased risk of myocardial infarction. Senate Finance Committee investigations in 2010 found that GSK had internal evidence of cardiovascular risk years before the Nissen publication and had not disclosed it to regulators. GSK settled with the US Department of Justice for $3 billion in 2012 — at the time the largest healthcare fraud settlement in US history — covering Avandia and other products. The FDA restricted Avandia to patients with no other options in 2010 and lifted the restrictions only in 2013 after further review.

A Reuters investigation published in December 2018 found that Johnson & Johnson knew for decades that its baby powder talc sometimes tested positive for asbestos, a known carcinogen, and did not disclose this to regulators or the public. Internal J&J documents dated from the 1970s through the early 2000s showed awareness of asbestos contamination in talc sourced from mines in Vermont and elsewhere. In 2018, a Missouri jury awarded $4.69 billion to 22 women who alleged asbestos-contaminated talc caused their ovarian cancer (Ingham v. Johnson & Johnson). J&J discontinued US and Canadian baby powder sales in 2020 and global sales in 2023. Two attempts to resolve talc liability through bankruptcy of a subsidiary (LTL Management) were rejected by federal courts in 2023.

JUUL Labs launched its e-cigarette in 2015 with marketing that regulators and litigants found deliberately targeted underage users: bright colours, social media influencers, flavoured pods, and campaigns that mirrored cigarette advertising strategies proven to recruit teen smokers. Between 2017 and 2019, teen e-cigarette use surged to epidemic levels — the FDA called it a "youth vaping epidemic." In June 2022, the FDA denied JUUL's marketing authorisation, citing inadequate safety data. In December 2022, JUUL settled a 33-state attorney general investigation for $462 million. Separate settlements with school districts and individual states totalled additional hundreds of millions. The targeting of minors is confirmed by internal documents, regulatory findings, and legal settlements.

Merck launched the painkiller Vioxx (rofecoxib) in 1999 despite internal data suggesting elevated cardiovascular risk. The VIGOR trial (2000) showed a five-fold increase in heart attacks versus naproxen; Merck downplayed the finding for four years. APPROVe (2004) confirmed the risk and Merck withdrew Vioxx globally. The FDA estimated 27,000 to 55,000 excess cardiovascular deaths during the drug's five years on the market. Merck settled MDL 1657 for $4.85 billion in 2007. Internal emails show executives debating how to "handle" the cardiovascular signal. This is a confirmed corporate concealment, not a disputed claim.

Theranos, founded by Elizabeth Holmes in 2003, claimed its proprietary Edison device could run hundreds of diagnostic tests from a single finger-prick of blood. The technology never worked as claimed. A 2015 Wall Street Journal investigation by John Carreyrou exposed the fraud. The company voided two years of Edison-based test results, affecting approximately 176,000 patients. Holmes was convicted of four counts of wire fraud (January 2022, sentenced to 11 years). President Balwani was convicted of 12 counts (July 2022, sentenced to nearly 13 years). Patients received false medical results; some made clinical decisions based on inaccurate data.

FTX, the cryptocurrency exchange founded by Sam Bankman-Fried (SBF), secretly transferred billions in customer deposits to its affiliated trading firm Alameda Research, which used the funds for investments, loans to executives, and political donations. When Alameda's balance sheet leaked in November 2022, a bank run ensued and FTX collapsed. SBF was convicted on seven counts of fraud and conspiracy in November 2023 and sentenced to 25 years. Testimony from co-conspirators Caroline Ellison and Gary Wang confirmed the Alameda auto-liquidation exemption and the deliberate nature of the commingling.

Tether Limited, issuer of the USDT stablecoin, claimed for years that each USDT was backed 1:1 by US dollars held in reserve. Investigations by the New York Attorney General (settled February 2021, $18.5M) and the CFTC (settled October 2021, $41M) confirmed that Tether had misrepresented its reserves — backing was at times composed of commercial paper, loans to Bitfinex, and other non-cash assets rather than pure dollar reserves. Tether produces periodic attestations but has never undergone a full independent audit. The stablecoin continues to operate and is the largest by market cap.

Mt. Gox, once the world's largest Bitcoin exchange, collapsed in February 2014 after announcing the loss of approximately 850,000 BTC (then ~$450M; worth billions at later prices). CEO Mark Karpelès initially claimed transaction malleability attacks were responsible. Independent blockchain forensics firm WizSec attributed the losses to systematic key theft beginning in 2011. Karpelès was convicted in March 2019 for data falsification — not theft. Alexander Vinnik, operator of BTC-e (a money laundering exchange), was indicted in 2017 for receiving proceeds of the Mt. Gox theft. The true mechanism remains partially contested.

TerraUSD (UST) was an algorithmic stablecoin designed by Terraform Labs and its CEO Do Kwon. In May 2022, the UST peg collapsed, triggering a "death spiral" that wiped approximately $40 billion in market value within days. The SEC filed fraud charges in February 2023. Do Kwon was arrested in Montenegro in March 2023 and extradited to the United States in 2025. Evidence at trial showed Kwon and colleagues had privately known the stablecoin mechanism was fragile and had concealed its prior near-collapse in May 2021.

Silicon Valley Bank (SVB) collapsed on 10 March 2023 in the second-largest US bank failure in history. Conspiracy claims attributed the failure to coordinated short-selling campaigns or deliberate destabilisation by financial actors. Federal Reserve, FDIC, and congressional investigations attributed the collapse to SVB's concentration of approximately $91 billion in long-duration mortgage-backed securities purchased at near-zero interest rates, which lost market value as rates rose. When SVB announced a $1.8 billion realised loss from selling securities on 9 March, a Twitter-accelerated bank run ensued. Short-seller conspiracy claims are unsupported.

Jahseh Dwayne Ricardo Onfroy (XXXTentacion) was shot and killed during a robbery outside a motorsports dealership in Deerfield Beach, Florida, on 18 June 2018. Four men were convicted of first-degree murder and armed robbery in October 2023: Dedrick Williams, Michael Boatwright, Trayvon Newsome, and Robert Allen. The prosecution established a robbery motive — the perpetrators targeted XXXTentacion for cash he was known to be carrying. The claim that a rival record label orchestrated the killing has no evidentiary basis and contradicts the conviction record.
