Hackers Claim Leaked Rosstat Data Shows 450,000 Russian Deaths

Hackers targeting Russia's state statistics agency have claimed leaked government records indicate up to 450,000 deaths resulting from Russia's full-scale invasion of Ukraine since 2022. Two anti-Lukashenko hacker collectives, Belarusian Cyberpartisans and Silent Crow, a pro-Ukrainian group, alleged on Saturday that Rosstat data showed between 394,000 and 450,000 war-related deaths among Russia's fighting forces or those connected to the conflict from February 2022 to August 2026.

The Belarusian group identified at least 393,881 deaths directly linked to military operations, while Silent Crow increased the toll to 450,100 by including non-combat military deaths and unspecified causes. Silent Crow reported annual deaths rising from approximately 19,000 in 2022 to over 182,000 in 2025, with most fatalities between ages 30 and 49.

According to Ukrainian mapping project DeepState, Russia has captured about 73,000 square kilometers of Ukrainian territory since the invasion began. Comparing Russia's territorial gains to Silent Crow's highest estimate, experts estimate roughly six war-related deaths per square kilometer seized. However, the authenticity of the leaked records and the hackers' casualty estimates remain unverified.

Independent Russian outlet Mediazona, working with BBC Russian and volunteers, reported 285,881 Russian military personnel killed in the war as of November 6, but journalists believe the actual toll is significantly higher, as Russia does not publish comprehensive figures on military losses in Ukraine.
