Leaked data from Russia’s state statistics agency, Rosstat, is reported to show that about 400,000 Russian nationals have died fighting in Ukraine since the full-scale invasion began nearly five years ago. Multiple outlets describe the material as death certificates or death records and say it was obtained after a cyberattack attributed to hacking groups linked to Belarus and Ukraine.
The reporting generally draws on the same cache, but they differ in the figures and emphasis. Some stories cite “more than 400,000” deaths, while others provide more specific counts such as roughly 392,700 war-related deaths since February 2022 and mention the possibility the true toll is higher, with some figures reaching around 450,000. Coverage also notes that the certificates include details such as age, residence, and location of death, offering what outlets call rare insight into causes including shelling and drones.
Outlets frame the leak differently: some foreground the scale and immediacy of troop losses, while others focus on how the data was accessed and the implications of using hacked administrative records. Across coverage, the core claim is the same: hacked Russian death records indicate Russia has suffered deaths in the conflict on the order of 400,000 or more.
