Hacked Rosstat data suggests 393,000 to 450,000 Russians killed in Ukraine war, hacker groups say

Summary

Hacker groups Cyberpartisans BY and Silent Crow say they hacked Rosstat, Russia's state statistics agency, and used its records to count Russians killed since the full-scale invasion of Ukraine, arriving at a tally of between 393,000 and 450,000. The Guardian reports that the leaked data contains more than 11 million death certificates, including details of age, place of residence and location of death. The Straits Times reports that almost 392,700 death certificates explicitly link fatalities to the war between February 24, 2022, and late August 2026. Euronews notes that these figures are the groups' claims and that its summary includes no independent verification. The Japan Times reports that the material, obtained by a Belarusian pro-opposition group and a Ukrainian hacker operation, gives rare insight into the war's true cost for Russia. The Sydney Morning Herald reports that military losses are a state secret, but that death certificates from the past five years cite causes such as shelling and drones.
