The attack occurred in the southern Russian city of Balakovo, according to the state-owned TASS news agency, which cited a senior Sberbank executive on Wednesday.
Sberbank Deputy Chairman Alexander Vedyakhin confirmed the incident but said the bank’s operations had not been disrupted.
“We confirm the attack on the data centre,” Vedyakhin said.
He added that all banking systems and customer services were functioning normally despite the strike.
Sberbank, which is state-owned, is Russia’s largest financial institution by assets and customer numbers, making its technological infrastructure a significant component of the country’s financial system.
The reported strike is the latest in a series of attacks on Russian data centres and digital infrastructure, amid an escalating exchange of drone and missile strikes between Moscow and Kyiv.
Earlier this month, Yandex, Russia’s largest technology company, reported at least three drone attacks on its data centres, resulting in damage and disruptions to some operations.
The incidents have raised concerns about the vulnerability of digital infrastructure, including facilities supporting banking services, communications and artificial intelligence development.
Meanwhile, the governor of Russia’s Saratov region, Roman Busargin, said a Ukrainian drone attack on Balakovo killed one person early Wednesday.
It was not immediately clear whether the reported fatality was directly connected to the strike on Sberbank’s data centre.
Russia’s Defence Ministry also claimed that Ukrainian forces launched more than 900 drones toward Russian territory and the annexed Crimean Peninsula overnight.
The ministry’s figures could not be independently verified.
Ukrainian authorities did not immediately comment on the reported attack on the Sberbank facility.
The latest developments come as both countries expand their long-range military operations beyond the front lines.
Russian forces have repeatedly targeted Ukrainian data centres, logistics facilities and other critical infrastructure in recent months, while Ukrainian drone operations have increasingly reached strategic facilities deep inside Russia.
The growing focus on technology infrastructure highlights the expanding nature of the conflict, with digital networks and computing facilities becoming increasingly exposed to military attacks.
Although Sberbank reported no disruption to its services, the latest strike underscores the security challenges facing critical financial and technological systems as the war continues.
