Hackers claim 450100 killed in Ukraine based on alleged Rosstat leak

English.Nv.Ua • November 7, 2026

Hacker group Silent Crow claims that Russia has lost 450,100 people killed in its war against Ukraine. The hackers allegedly obtained the data after breaching databases belonging to Russia's Federal State Statistics Service (Rosstat) together with the Belarusian Cyber Partisans, Radio Liberty reported on Saturday, Nov. 7.

According to Silent Crow, the hackers gained access to the database of Rosstat's Demography information system, which contains census records and information on citizens' causes of death through August 2026. The data cannot be independently verified.

According to the figures released by the hackers, the largest number of those killed — 100,000, or 21.7% — came from Russia's Volga Federal District. More than half, 54.9%, were killed in Donetsk Oblast. Most of those killed were between 30 and 49 years old.

According to the hackers' calculations, deaths increased with each year of the war: approximately 19,000 in 2022, more than 42,000 in 2023, nearly 110,000 in 2024 and more than 182,000 in 2025. In 2026, another approximately 40,000 people were killed, according to incomplete data.

Silent Crow said an average of 18,280 new records had been added to the database each month over the past six months. The hackers predict that the total number killed in the war will reach between 508,000 and 543,000 by the end of the year.

Since the beginning of Russia's full-scale invasion, independent Russian outlet Mediazona, together with the BBC and volunteers, has been compiling a list of Russian military personnel killed in the war using open sources. The list currently contains 285,881 names.

According to an estimate by Meduza and Mediazona based on inheritance records, approximately 352,000 Russians have been killed.

In September, British Chief of the Defense Staff Richard Knighton said the number of Russian troops killed had exceeded half a million, while total casualties, including the wounded, had reached 1.5 million. According to the General Staff of the Armed Forces of Ukraine, Russia's total losses, including those killed and wounded, exceed 1.6 million.

Silent Crow has carried out similar attacks before. In particular, the group and the Belarusian Cyber Partisans previously claimed responsibility for a cyberattack on Aeroflot.

Cyberattack Exposes 450,000 Russian War Deaths Amid Ukraine Conflict A cyberattack by Belarusian Cyberpartisans and Silent Crow on Russia's Federal State Statistics Service (Rosstat) has reportedly leaked data indicating that between 394,000 and 450,000 Russians have died in the ongoing war in Ukraine since February 2022. The hackers accessed Rosstat's Demography database, which includes death records up to August 2026. The leaked figures suggest that the war has become Russia's deadliest conflict since World War II, with significant casualties reported in the Donetsk region. The authenticity of the data has not been independently verified, and Rosstat has denied that its databases were compromised. The leaked information includes both combat and non-combat deaths, with estimates varying based on methodology. The total death toll is likely higher, as it does not account for missing soldiers or foreign fighters. This incident highlights the challenges in obtaining accurate casualty figures amid the ongoing conflict. 4 sources 60
