Cyberpartisans BY and Silent Crow claim they breached Russia’s state statistics agency Rosstat and extracted data indicating that between 393,000 and 450,000 Russians have died in the war in Ukraine.

Euronews and The Moscow Times both reported the hackers’ claim. Euronews cited a tally ranging from 393,000 to 450,000 deaths, while The Moscow Times highlighted a figure of approximately 450,000. The figures are presented as an estimate derived from data the groups say they obtained or counted after the alleged breach.

The Moscow Times further reported that the alleged statistics indicated the war had become the fourth most common cause of death in Russia since 2022. That detail comes from a single report and remains tied to the allegedly released data.

The supplied reporting does not establish that Rosstat was breached, that the released material is authentic, or that Russian authorities officially confirmed the figures. The reported death toll therefore remains an unverified hacker estimate rather than a confirmed official count.
