Putin Faces Major Blow As Cyber Attack Claims 450,000 Russian Soldiers Killed In Ukraine

A major cyber attack targeting Russia's state statistics agency has reportedly exposed records that activists say could reveal the scale of Moscow's military losses in Ukraine. The groups behind the operation claim their analysis points to as many as 450,100 Russian military deaths since the full-scale invasion began in February 2022.

However, the leaked figures have not been independently verified, and Russian authorities dispute claims that their databases were compromised.

Russia Ukraine War: Cyber Attack Reveals Alleged Military Death Toll

The cyber operation was reportedly carried out by pro-Ukrainian hacking group Silent Crow alongside the Belarusian Cyber Partisans, organisations outlawed by the Kremlin as extremist groups.

According to the activists, they accessed records held by Russia's state statistics agency, Rosstat, containing death registrations covering the period from February 2022 to August 2026. The groups subsequently analysed the material to estimate the number of Russian service personnel killed during the conflict.

Silent Crow put the estimated death toll at approximately 450,100 troops, while the Belarusian Cyber Partisans reported at least 393,881 deaths using narrower criteria focused on documented military operations.

The difference reflects the separate methodologies applied by the two groups, and neither estimate has been confirmed through an independent audit. Rosstat acknowledged an intrusion reportedly occurred between late October and early November but maintained that its databases remained secure and unaffected.

The alleged disclosure has attracted attention because Moscow has largely stopped publishing regular figures on its military fatalities. Russia last released an official death toll in September 2022, when it reported fewer than 6,000 troops killed. Western governments and independent analysts have since produced substantially higher estimates of Russian losses.

Russian Military Losses Raise Questions Over Putin's War Strategy

The figures released by the hacking groups broadly resemble some Western assessments of the scale of Russian casualties, although comparisons depend on whether estimates include deaths alone or both killed and wounded personnel. British defence assessments have previously estimated that Russian military deaths could approach 500,000. Air Chief Marshal Sir Rich Knighton, head of the UK Armed Forces, has also warned that Russia's combined military casualties have reached approximately 1.5 million since the invasion began.

Janis Kluge, an expert at the German Institute for International and Security Affairs, described the breach as one of the most significant disclosures of Russian casualty data since the war began.

Security analysts have warned that the fighting has become increasingly costly, with Russian forces sustaining substantial losses while seeking relatively limited territorial advances. Nevertheless, the precise scale of Russian fatalities remains difficult to establish because Moscow does not publish comprehensive, independently verifiable figures.

Russia continues to recruit personnel to replenish units fighting in Ukraine, with reports suggesting recruitment has been running at approximately 1,200 people a day. The country has also received military support from North Korea, including the deployment of troops to assist Russian forces.

Projections that Russia could suffer more than 200,000 additional military deaths in 2026 depend on casualty-rate assumptions and should not be treated as confirmed outcomes.

Ukraine War Escalation: Russian Strikes Intensify Ahead Of Peace Talks

The reported data breach comes amid continued Russian attacks on Ukrainian cities and infrastructure ahead of US-brokered diplomatic talks in Abu Dhabi. Recent strikes on Kyiv reportedly damaged transport infrastructure, residential areas and a nursery, leaving nine people injured.

Another attack on a school being used as a humanitarian refuge was reported to have killed 55 people, while emergency workers searched through the damaged building.

Ukrainian President Volodymyr Zelensky has accused Moscow of intensifying its bombardment in an effort to pressure Ukraine into accepting territorial concessions before negotiations begin.

The attacks have added to concerns over the prospects for a diplomatic settlement as fighting continues on multiple fronts. The allegations surrounding the casualty data have also renewed scrutiny of the human cost of Russia's invasion.

Figures attributed to Ukraine's General Staff and Ministry of Defence indicate that Russian military casualties rose sharply during October 2026. The supplied reports put Russian losses for that month at approximately 54,400 personnel and claim that more than 100,000 troops were killed or wounded over the autumn period. They also cite a daily loss of 2,250 Russian personnel on 21 October, although these battlefield figures have not been independently verified.

The reported October losses underline the uncertainty surrounding casualty estimates released by the parties involved in the conflict. Ukrainian and Western assessments often differ from Russian figures, while the alleged Rosstat data has yet to undergo independent verification. Until further evidence becomes available, the precise number of Russian soldiers killed in Ukraine remains disputed.
