Hackers Say Leaked Rosstat Records Show 450,100 Russian War Dead

Two hacker groups say they have stolen death records from Rosstat, Russia's state statistics agency, and that they show 450,100 war-related deaths between February 2022 and 28 August 2026. The pro-Ukrainian group Silent Crow published that figure on 7 November. The Belarusian Cyberpartisans, who claimed the hack jointly, give a stricter count of 393,881. None of it has been independently verified. Rosstat confirms a cyber attack but denies that any data was leaked.

Key takeaways

• The claim: Silent Crow says the records show 450,100 war-related deaths registered from February 2022 to 28 August 2026. The Cyberpartisans count 393,881, including only deaths the records tie explicitly to military operations.
• Not verified: the records have not been independently checked. Rosstat says its attackers did not compromise its databases or leak any information.
• The pace: by Silent Crow's count, about 19,000 died in 2022 and more than 182,000 in 2025, nearly ten times as many.
• The map: 54.9% of the deaths were recorded in Donetsk Oblast, and 21.7% of the dead came from the Volga Federal District.
• The context: Russia has not published its own military death toll since September 2022.

Confidence: CLAIMED, UNVERIFIED. The figures are the hackers' own analysis of data RAGE X has not seen. They are reported here as claims, not as findings.

What the hackers say#

Rosstat says its systems were attacked between 29 October and 1 November 2026 and that the attackers defaced its main website and regional portals with messages from the two groups. The hackers say they copied between 10 TB (Cyberpartisans) and about 23 TB (Silent Crow) of data, including medical death certificates, and that Silent Crow had been inside the network for roughly six months before the attack.

On 7 November, Silent Crow published an interactive analysis of what it says is Rosstat's extract of death certificates. It covers deaths registered between February 2022 and 28 August 2026 and counts seven types of record linked to the war, including cause-of-death code Y36, the international code for "operations of war".

Both groups are designated "extremist" in Russia. The Kyiv Independent said it could not independently verify the records or the casualty estimates.

Every count compared#

Notes on the table:

• Named dead. The most recent Mediazona and BBC Russian count RAGE X could confirm independently was 242,747 on 27 August, reported by the Kyiv Independent. The figure of about 285,000 is the later tally used in RAGE Intel's graphic and is attributed to the two outlets' list; it has not been re-checked against their current page. Mediazona says its list is incomplete, because not every death is publicly reported.
• Other estimates. Mediazona and Meduza have also published an estimate of about 352,000 based on inheritance records, according to Kyiv Post.
• UK estimate. Air Chief Marshal Sir Richard Knighton, Britain's Chief of the Defence Staff, said on 11 September 2026 that more than 500,000 Russian troops have been killed, and about 1.5 million killed or wounded. He said the figures broadly matched estimates from Ukraine's military.
• Russia. The last official Russian military death toll was published in September 2022.

The pace#

By Silent Crow's count, deaths rose from about 19,000 in 2022 to more than 182,000 in 2025. Most of the dead were aged between 30 and 49. The group says the records show an average of 18,280 new records a month over the last six months of data.

Silent Crow also projects a total of 562,979 to 596,888 by the end of 2026, a model that corrects for registration lag. Reports of the analysis do not agree on the projection: the New Voice of Ukraine gives a range of 508,000 to 543,000.

Where they came from, and where they died#

• Where they died: the records place 54.9% of the deaths in Donetsk Oblast. For 17% of the records, no place of death is given.
• Where they came from: by registered residence, the Volga Federal District, which includes Bashkortostan, Tatarstan and Samara, supplied 21.7% of the dead, about 100,000 people. The Central Federal District supplied 16.9%.
• Land and deaths: Silent Crow's analysis sets the deaths against 73,080 km² of Ukrainian land it counts as seized, or 6.2 dead per square kilometre. RAGE X has not checked the land figure.

What the leak can't prove#

• It is unverified. Rosstat admits an attack but denies any data was leaked. Only the hackers have seen the data, and independent researchers have not yet confirmed it.
• It is not only soldiers. Code Y36 does not separate service members from civilians killed in strikes. The analysis says 99.4% of the dead are men, which points strongly to military deaths but is not proof.
• The numbers do not add up cleanly. The yearly figures shown in Silent Crow's analysis total 392,485 on RAGE Intel's addition, well below the 450,100 headline. The reports we reviewed do not explain the difference in full; some of it may come from records with no year or no stated cause.

Our read · RAGE Intel assessment

Treat 450,100 as a claim worth taking seriously, not a finding. It sits between the stricter 393,881 count from the same hack and the UK's estimate of more than 500,000, so its scale is consistent with other estimates. That is not the same as verification: nobody outside the two groups has examined the data, and the gap between the headline total and the yearly figures is unexplained.

The spread of numbers in the table is mostly a difference of method: named dead, strictly military records, all war-linked records, and a count adjusted for registration lag. The hackers' timing and aims should also be kept in mind: both are pro-Ukrainian groups publishing during an active war.

This is an assessment, not a finding. It will change if independent researchers examine the records, or if Rosstat or the Russian government says more about the breach.

What to watch#

• Independent checks of the records by researchers, Mediazona or other media.
• Any further statement from Rosstat or the Russian authorities about what was taken.
• A fuller release of the data, and whether the yearly figures and the headline total are reconciled.

This story is developing. RAGE X will update it as new information is confirmed.
