Leaked Russian Records Suggest Over 400,000 War Deaths in Ukraine

A leak of internal Russian statistical records has indicated that more than 400,000 Russian personnel have died since Moscow launched its full-scale invasion of Ukraine, a figure that would far exceed combined Russian and Soviet military deaths in all conflicts since the Second World War.

According to reports, the Belarusian opposition-linked group Cyber Partisans and the Ukrainian hacking collective Silent Crow accessed roughly 11 million death certificates held by Rosstat, Russia's state statistics agency, following a breach on November 1. The groups said 412,576 of those certificates were specifically tied to fatalities in the war. Rosstat acknowledged that a breach had occurred but denied that any sensitive information was obtained, and the figures could not be independently verified.

The claimed toll is roughly nine times greater than the combined Soviet and Russian fatalities recorded in all wars since 1945, according to the reports. It also broadly tracks estimates published by Western intelligence and independent conflict analysts, who have long argued that Moscow's attritional battlefield tactics have produced very high casualties.

The leak follows separate findings by the Russian outlet Mediazona, which identified nearly 286,000 military personnel killed while deployed in Ukraine and estimated the true figure could be closer to 500,000. A subsequent analysis by The Economist reached a similar conclusion. Ukrainian President Volodymyr Zelensky said recently that Russia suffered more than 54,000 casualties in October alone, the highest monthly total since the war began.

The reported losses have intensified debate over whether Moscow will order another large-scale mobilization. Analysts have suggested the Kremlin is wary of a fresh draft because of the domestic backlash that followed the previous call-up. The casualty figures remain disputed and unconfirmed, and independent verification of the leaked data is not currently possible.
