A major cyber attack on Russia's state statistics agency has revealed that as many as 450,000 Russian soldiers have died in Ukraine, exposing the devastating scale of Moscow's battlefield losses.
Hackers infiltrated Rosstat and extracted thousands of sensitive records containing official death certificates logged between February 2022 and August this year. The joint operation was carried out by the pro-Ukrainian activist group Silent Crow and the Belarusian Cyber Partisans, both officially outlawed by the Kremlin as extremist outfits.
Leaked Data Analysis
Silent Crow analysed the compromised registries and calculated the Russian death toll at 450,100 troops. The Belarusian Partisans applied narrower analytical filters restricted strictly to recorded military operations, confirming at least 393,881 combat deaths.
Rosstat acknowledged an intrusion occurred between late October and early November, but insisted its databases remained secure and untouched. While the leaked registries have not undergone independent auditing, the numbers closely correspond to intelligence assessments compiled by Western allies.
Western Estimates and Warnings
British defence estimates previously calculated that roughly 500,000 Russian personnel had been killed. Air Chief Marshal Sir Rich Knighton, head of the UK Armed Forces, recently warned that total Russian casualties, encompassing both dead and wounded troops, have reached 1.5 million since the full-scale invasion began.
Security analysts warn that the war has entered its most lethal phase yet. Janis Kluge, an expert at the German Institute for International and Security Affairs, described the breach as the most significant leak of Russian casualty data since the conflict started, noting that the frontline has never been deadlier.
Moscow's Secrecy and Recruitment
Moscow has refused to publish official updates regarding its losses since September 2022, when it claimed fewer than 6,000 troops had been killed. To replace daily frontline losses estimated between 1,000 and 1,400 men, Moscow relies on aggressive recruitment drives that net around 1,200 enlistees daily, supplemented by more than 10,000 North Korean troops drafted to reinforce depleted units.
If current rates continue, Russia is projected to suffer over 200,000 extra fatalities in 2026 alone.
Escalating Strikes and Record Casualties
The leak comes as Moscow escalates air strikes against Ukrainian infrastructure ahead of US-brokered talks in Abu Dhabi. Recent bombardments across Kyiv damaged key transport links, residential sectors and a nursery, injuring nine. That attack followed a deadly strike on a school serving as a humanitarian refuge, which claimed 55 lives and left emergency teams searching through heavily damaged wreckage.
Ukrainian President Volodymyr Zelensky warned the intensified barrage is a calculated Kremlin effort to force territorial concessions before diplomats meet.
Russia suffered its worst month of the war in October 2026, losing 54,400 troops for just a few miles of land. Over 100,000 Russian soldiers were killed or wounded in autumn alone. Last month alone, its casualties exceeded the Soviet Union's losses during its decade-long war in Afghanistan. According to Ukraine's General Staff and Ministry of Defence, the figure marks the highest monthly casualty figure on record, with the Russian military never having suffered losses on such a scale before. On October 21 alone, the Russian military lost 2,250 troops - another record-breaking figure.
