A report based on hacked Russian statistics-agency records said about 400,000 Russians have died fighting in Ukraine

More context

Bloomberg reported that confidential records from Russia’s statistics agency, Rosstat, list roughly 400,000 war-related deaths among people fighting for Russia in Ukraine since the full-scale invasion. The data, drawn from more than 11 million death certificates, were obtained by Belarusian pro-opposition group Cyber Partisans and Ukrainian hacker operation Silent Crow and shared with Bloomberg and other outlets. The groups’ estimates differ: Cyber Partisans identified at least 393,881 deaths in records explicitly attributing them to military activity by the end of August 2026, while Silent Crow estimated 450,100 using broader categories, including noncombat military deaths and some deaths without a specified cause. Rosstat acknowledged cyberattacks from Oct. 29 to Nov. 1 but denied its databases were compromised or information leaked. The Kyiv Independent said it was unable to establish whether the leaked records or estimates were authentic.
