Leaked Russian death certificates reveal scale

What's happened

Hackers have published a cache of more than 11 million Russian death certificates. Analysts and outlets using the dataset have identified roughly 392,000–412,000 records that explicitly link fatalities to the war from Feb. 24, 2022 through late August 2026; experts say the data likely undercounts total Russian military deaths.

What's behind the headline?

What the leak shows

• The cache contains more than 11 million death certificates, including age, residence and place of death, and spans at least Feb. 24, 2022 to late August 2026.
• Across outlets analysing the material, roughly 392,000–412,576 certificates explicitly reference the war through cause codes or free-text mentions such as “military operation,” “shelling” or “drones.”

Why this matters

• The dataset has provided the most granular publicly available window into Russian wartime fatalities since 2022. It will force new recalculations of battlefield losses, regional impact and the timing of casualty spikes in late 2024 and 2025.

Key inferences and consequences

• The figures will likely increase pressure on researchers and Western intelligence to reconcile their estimates; several analysts argue the true military death toll is closer to about 500,000 when delayed registrations and missing personnel are counted.
• The data will expose uneven burdens across Russia: poorer eastern regions show disproportionately high war-related mortality among men aged 18–49, while Moscow and St Petersburg show lower shares.
• Political consequences will follow. The leak will force Russian authorities to respond domestically and internationally; Moscow has already confirmed a hack and denied sensitive disclosures, but the material will fuel scrutiny of conscription, recruitment and regional mobilisation policies.

What comes next

• Researchers will cross-match names and service records and will publish more detailed casualty reconstructions. This will increase the likelihood that independent tallies of military deaths will rise over the coming weeks.
• The leak will keep casualty accounting at the centre of diplomatic talks and public debate, and it will complicate Russian messaging about the war’s human cost.

How we got here

Belarusian Cyber Partisans and Ukrainian Silent Crow have released the cache, which Reuters and multiple outlets have analysed. Russian statistics agency Rosstat has confirmed a breach but denied sensitive data leaked. Independent analysts say official tallies have been restricted and the dataset offers new detail on regional and temporal patterns of wartime deaths.

Our analysis

Bloomberg has consistently described how the data originated: "the information comes from a cache of more than 11 million death certificates" obtained by Cyber Partisans and Silent Crow and shared with a small group of outlets. (Bloomberg, Nov. 8–11, 2026). The Guardian has provided the most detailed public tally, saying the dataset contains 412,576 certificates "explicitly linked the fatalities to the war, either through official cause-of-death codes or written references to combat and military operations," and quoted Janis Kluge as saying "the data looks authentic, and it's very rich." (The Guardian, Nov. 9, 2026). The Japan Times presented a slightly lower wartime-linked count—"almost 392,700"—noting the dataset's coding and free-text indicators for war causes (The Japan Times, Nov. 9 and Nov. 3, 2026). The outlets are aligned on provenance: Belarusian Cyber Partisans and Ukrainian Silent Crow announced the breach on Nov. 1 and shared the files with a small group of newsrooms. Rosstat has "confirmed it had been hacked but denied that any sensitive information had been leaked," The Guardian reported. Analysts quoted across publications warn the dataset likely undercounts fatalities because of registration delays, missing personnel and unidentified remains; The Guardian cited Janis Kluge estimating the true death toll "closer to 500,000." Bloomberg and The Japan Times focused on the scope and technical details of the cache, while Ukrainian and Western sources cited in other coverage have linked October 2026 battlefield fighting and drone campaigns to spikes in casualties reported by Kyiv. Read The Guardian for the detailed figure and expert comment: "412,576 death certificates explicitly linked the fatalities to the war" (The Guardian, Nov. 9, 2026). Read Bloomberg for provenance and datasets: "more than 11 million death certificates" (Bloomberg, Nov. 8–11, 2026). Read The Japan Times for the alternative count and dates: "almost 392,700" wartime-linked certificates (The Japan Times, Nov. 9, 2026).

  Sloviansk is a city in Donetsk Oblast, northern part of the Donbas region of eastern Ukraine. The city was known as Tor until 1784. While it did not actually belong to the raion itself, Sloviansk served as the administrative center of the Sloviansk Raion (district) until its abolition on 18 July 2020. Sloviansk was one of the focal points in the early stages of the war in Donbas, in 2014, as it was one of the first cities to be seized and controlled by Russian-backed rebels (separatists), in mid-April 2014. Ukrainian forces then retook control of the city in July 2014, and since then, Sloviansk has been under Ukrainian control. The 2001 population of Sloviansk was 141,066. Largely due to the ongoing war in Donbas, by early 2022 this was down to 105,141. Following the 2022 Russian invasion of Ukraine, the city's population fell markedly, to around 24,000 by July 2022, due to shelling, and ongoing war, according to Ukrainian authorities. In April 2023, The Financial Times estimated the population to have recovered to 40–50,000.
