Hackers claim nearly 400,000 Russians killed in war after Rosstat hack

The hacker groups Silent Crow and Cyber Partisans BY, which claim to have hacked Russia's Federal State Statistics Service (Rosstat), have posted data indicating that more than 410,000 Russians have died as a result of combat operations and their consequences since the beginning of Russia's full-scale invasion of Ukraine.

Details: According to Silent Crow's calculations, as of the end of August 2026, Rosstat's database contained records of more than 410,000 deaths directly linked to combat operations or their consequences. These refer to deaths recorded under the relevant International Classification of Diseases codes and records of deaths during military operations.

The group's broader estimate, however, stands at 450,100 deaths. This figure also includes nearly 15,000 non-combat deaths among military personnel, including those caused by illness, road accidents and suicide, and 575 deaths classified as "terrorist attacks".

Another hacker group, Cyber Partisans BY, calculated a total of 393,881 deaths using its own methodology, Meduza reported.

Background: President Volodymyr Zelenskyy said in July that Russian forces had suffered a total of "1,600,000 losses, including around 700,000 deaths" in the war.
