French tax agency breach exposes taxpayer data as hacker claims 678,000 records
France's finance ministry (
@DGTresor) confirmed attackers accessed tax authority systems in late June and extracted individual and professional taxpayer data. A hacker called ZeroBytes claims roughly 678,000 records, including income details, a figure officials have not confirmed.
The leak lands amid France's wave of wrench attacks, with 77 verified crypto-linked kidnapping and extortion cases since January versus 45 in all of 2025, though no link to the breach has been established.
