'Wizard' hacker charged after financial records of nearly every Bulgarian exposed

Cyber attack compromised records on incomes, tax, health insurance and loans of millions of people

A 20-year-old cybersecurity worker has been arrested in Bulgaria and charged with hacking the personal and financial records of millions of taxpayers, as police continue to investigate the country's biggest ever data breach.

Bulgaria's NRA tax agency is facing a fine of up to a20m ($22.43m) over the hack, which was revealed this week and is thought to have compromised the records of nearly every working adult among the country's population of 7 million.
