Hackers Claim Leaked Rosstat Data Shows 450,000 Russian Deaths

Belarusian Cyberpartisans and Silent Crow claim that records allegedly stolen from Rosstat reveal a far larger war-linked death toll than Russia publicly reports. They place the total between 394,000 and 450,000 from February 2022 through August 2026. The figures include people fighting for Russia or otherwise connected to the war.

The lower estimate identifies 393,881 deaths explicitly linked to military operations. Silent Crow’s upper estimate reaches 450,100 because it also includes non-combat military deaths and some cases whose causes of death were unspecified. It also reported that annual deaths rose sharply, from about 19,000 in 2022 to more than 182,000 in 2025.

These numbers remain allegations, not independently confirmed findings. The article says the leaked records and the hackers’ estimates have not been independently verified. Russia does not publish comprehensive military-loss figures, making the claims significant but still uncertain.

Rosstat is Russia’s State Statistics Service. Its role is to collect, organize, and publish official statistics about the country. That makes it a potentially important source for understanding population changes and registered deaths, including patterns that might relate to wartime losses.

The hackers say they obtained data from Rosstat and used it to identify deaths linked to military operations, non-combat military causes, and unspecified causes. The article does not describe the database, the records’ precise fields, or the exact method used to connect individual deaths to the war. Those missing details matter when judging the estimate.

The alleged records could therefore offer a different view from Russia’s public statements, especially because Russia does not publish comprehensive figures for military losses in Ukraine. However, the article stresses that neither the leaked records’ authenticity nor the casualty calculations has been independently verified.

The Belarusian Cyberpartisans identified at least 393,881 deaths explicitly connected to military operations. Silent Crow gave a higher estimate of 450,100 deaths. Both figures cover the period from February 2022 to August 2026 and include people fighting on Russia’s side or otherwise linked to the war.

The estimates differ because they use different inclusion rules. The lower figure focuses on deaths explicitly linked to military operations. Silent Crow adds non-combat military deaths and certain cases where the cause of death was unspecified. That broader definition produces the range of roughly 394,000 to 450,000.

The article also reports a major yearly increase, from around 19,000 deaths in 2022 to more than 182,000 in 2025. These figures are claims from the hacking groups, and their source records and calculations have not been independently verified.

Mediazona, working with BBC Russian and volunteers, published a figure of 285,881 Russian military personnel killed in the war. The hackers’ estimates are higher: 393,881 deaths explicitly tied to military operations and up to 450,100 under Silent Crow’s broader count.

Compared with Mediazona’s figure, the lower hacker estimate is about 108,000 higher, while the upper estimate is about 164,000 higher. The main reason is scope. Silent Crow includes non-combat military deaths and some cases with unspecified causes, while Mediazona’s published figure is described specifically as Russian military personnel killed.

The figures should not be treated as identical measurements. Mediazona’s estimate was published with BBC Russian and volunteers, while the hackers’ figures came from allegedly leaked Rosstat records. The article says the leaked data and casualty estimates have not been independently verified, and Russia publishes no comprehensive military-loss total.

The comparison links territorial expansion with human loss. DeepState estimates that Russia has captured roughly 73,000 square kilometers of Ukrainian territory since the full-scale invasion began. Using Silent Crow’s upper death estimate, the Kyiv Independent calculated about six war-related deaths for every square kilometer seized.

The calculation divides roughly 450,100 alleged deaths by approximately 73,000 square kilometers. It is not a measure of deaths occurring inside each square kilometer, nor does it prove that every death directly produced a territorial gain. Instead, it expresses the relationship between two broad totals: claimed war-related deaths and estimated captured territory.

That ratio highlights the human price attached to Russia’s territorial gains. It also depends on uncertain inputs. The territory figure comes from DeepState, while the death figure comes from Silent Crow, and the article says the leaked records and casualty estimates have not been independently verified.

The Belarusian Cyberpartisans are described as an anti-Lukashenko hacker collective. Silent Crow is described as a pro-Ukrainian hacker group that targets Russian institutions. Their political positions help explain why they would seek information from Russian government systems during the war.

The groups said they stole data from Russia’s State Statistics Service, or Rosstat. They then presented alleged records that they said showed between 393,881 and 450,100 war-linked deaths. Their stated target was a government institution holding statistical information, and the reported goal was to reveal casualty figures Russia does not publish comprehensively.

The article does not provide a detailed account of the operation, the groups’ exact methods, or every reason for targeting Rosstat. It does establish that both groups are hostile to the governments or institutions involved: the Cyberpartisans oppose Lukashenko, while Silent Crow supports Ukraine and targets Russian institutions. The data remains unverified.

A wartime death toll can be estimated by assembling available evidence when official reporting is incomplete. The article gives several examples: alleged Rosstat records, Mediazona’s work with BBC Russian and volunteers, and estimates based on reported military deaths. Each approach tries to measure losses despite Russia not publishing comprehensive figures.

Methods can count different populations. The Belarusian Cyberpartisans counted 393,881 deaths explicitly linked to military operations. Silent Crow reached 450,100 by adding non-combat military deaths and some unspecified cases. Mediazona published 285,881 Russian military personnel killed. These totals therefore do not measure exactly the same category.

Estimates can also differ because records may be incomplete, classifications may vary, and some deaths may have unclear causes. The article does not explain every technical method behind the figures. It does state that the leaked records and hacker estimates have not been independently verified, while Mediazona believes its own military toll is considerably higher.
