Beeline Breach

In 2019, a significant data breach emerged when a legacy database from 2016 maintained by the Russian telecommunications operator Beeline was exposed online, compromising the personal information of approximately 8.7 million customers. The leaked data included sensitive details such as full names, home addresses, and phone numbers. Although Beeline later clarified that the exposed information was outdated and asserted that corrective measures had been taken—including identifying and punishing those responsible—the company addressed the incident.
