The personal details of millions of Sberbank customers may have been leaked, in what would be the largest-ever data breach in Russian banking, according to cyber security experts.
Analysts at cybersecurity firm DeviceLock found personal information relating to up to 60 million Sberbank credit card holders for sale on the black market. They were able to analyse the data of around 200 supposed customers — provided to them by the seller — and verified their authenticity.
“This is the largest and most detailed banking database that has ever appeared on the black market,” DeviceLock founder Ashot Oganesyan said.
“In the world ranking of bank leaks, this can be considered a large incident. For the Russian market, this is an absolute record, at least for the last ten years,” he told The Moscow Times.
