Personal data belonging to millions of Bulgarians has been stolen in a cyber-attack on the country's tax agency.
According to a local cyber-security researcher, most adults in the country of seven million people are likely to have had some data compromised. Bulgarian authorities have arrested a 20-year-old man on suspicion of involvement in the attack. Among the stolen data were names, addresses and even some details of personal income, local media reported. The tax agency now faces a fine of up to 20 million euros (£18m), a representative of the Commission for Personal Data Protection said. "It is safe to say that the personal data of practically the whole Bulgarian adult population has been compromised,"
