A hacker is selling a trove of French tax records that could expose more than 678,000 people and businesses, including Bitcoin holders, to phishing, identity theft, and targeted attacks.

According to a report by French cybersecurity outlet FrenchBreaches, a hacker is selling records allegedly stolen from France’s tax authority, the DGFiP, during a June breach for several thousand euros.

“More bad news for Bitcoiners living in the leading country for wrench attacks,” Chief Security Officer at Bitcoin security platform Casa Jameson Loop wrote on X. “The French tax authority has been hacked, and 678K records leaked.”

FrenchBreaches said the database contains records on 392,867 individuals and 285,570 professionals, including 26,805 people with reference tax income of at least $116,000, 386 above $1.16 million, and eight above $11.6 million; the hacker is reportedly offering the file for several thousand dollars.
