BulgarianNationalRevenueAgency Data Breach (2019)

The Bulgarian National Revenue Agency (NRA) suffered a significant data breach in 2019, resulting in the exposure of personal and financial data of nearly 5 million Bulgarian citizens. The breach, which was the largest in Bulgaria's history, involved the theft of 21 terabytes of data. The compromised data included individuals' full names, personal identification numbers (PINs), addresses, income data, and information related to health insurance and the country's commercial register. The breach was acknowledged by the NRA in July 2019, a month after it occurred.
