Hackers claim leaked Russian records show up to 450,000 war deaths in Ukraine

Two hacking groups say they have obtained records from Russia's state statistics agency pointing to hundreds of thousands of Russian deaths in the war in Ukraine.
The claims
According to reports on Monday, 9 November 2026, the pro-Ukrainian group Silent Crow and the Belarusian Cyber Partisans said they accessed an internal database at Rosstat containing information from death certificates from February 2022 to August 2026. Silent Crow, which published the data, put the death toll at about 450,100, while the Belarusian Cyber Partisans, using a narrower method that counted only records naming military operations as the cause of death, put it at 393,881. The figures have not been independently verified.
Russia's response
Rosstat acknowledged that its systems were targeted between 29 October and 1 November but said no databases were compromised. Russia has banned both groups as 'extremist organisations'. Moscow has rarely given official figures for its military losses.
Background
Russia launched its full-scale invasion of Ukraine in February 2022. Independent estimates of Russian military deaths have varied widely, and both sides have been accused of under-reporting their own losses. The Belarusian Cyber Partisans also oppose the government of Belarusian President Alexander Lukashenko, a close ally of Moscow.
