Ukraine has lost over 1.7 million troops – leaked docs

The casualties are allegedly detailed in a digital card index of the country’s armed forces obtained by Russian hackers

Ukraine has allegedly lost more than 1.7 million troops killed and missing, multiple media outlets reported on Wednesday, citing a digital card index reportedly from the country’s armed forces.

Russian hacking groups have claimed to have obtained the information by gaining access to the personal computers and local networks of the Ukrainian General Staff. The database is said to include the full names of deceased soldiers, descriptions of the circumstances and places of their death or disappearance, personal data, next of kin, and photos.

The entries suggest that since the escalation of the Ukraine conflict in 2022, Kiev’s forces have lost a total of 1,721,000 servicemen. 118.5 thousand were apparently killed in 2022, 405.4 thousand in 2023, 595 thousand in 2024 and a record 621 thousand in 2025.

Hackers from the groups Killnet, Palach Pro, User Sec and Beregini are said to have obtained terabytes of information about the Ukrainian military. Aside from personnel losses, the groups allegedly also possess the personal data of the command of the Special Operations Forces and the Main Intelligence Directorate, lists of all countries that have supplied weapons to Kiev and lists of all weapons transferred from 2022 to 2025.

This Ukrainian casualty estimate far exceeds losses previously reported by Kiev.

In February, Ukraine’s Vladimir Zelensky told CBS News that since 2022, just 46,000 Ukrainian soldiers had been killed, with another 380,000 wounded. The estimate was widely questioned even in Western media, with the France’s Le Monde reporting last month that “the real death toll is likely much higher,” citing Ukraine’s increasing efforts to build military cemeteries.

The Russian military has consistently reported higher casualties among Ukrainian servicemen, claiming their losses particularly surged following Kiev’s unsuccessful counteroffensive in 2023. As of February, more than 1.08 million Ukrainian troops had been killed or wounded, according to Moscow’s estimates.
