France’s finance minister has confirmed that hackers breached the system of the country’s public finance directorate in late June and stole taxpayer data covering both individuals and businesses. FrenchBreaches, a platform that tracks cyberattacks in France, said the incident affected about 678,437 people, or roughly 1% of the country’s population, while noting that the final figure is still under investigation. The exposed records reportedly include names, dates of birth, home addresses, phone numbers, email addresses, tax identification details and income data. The reported dataset also contains a notable number of higher-income profiles: nearly 27,000 people with taxable income of at least 100,000 euros, 386 above 1 million euros, and eight above 10 million euros. According to the report, the database has been offered for sale on a dark web marketplace for several thousand euros. The attacker, using the name ZeroBytes, claimed to have extracted the records through an internal search tool before access was discovered and cut off. The leak has drawn attention in the crypto sector because violent "wrench attack" robberies targeting crypto holders have increased in France in recent years.

France’s finance minister has confirmed that hackers breached the system of the country’s public finance directorate in late June and stole taxpayer data tied to both individuals and businesses.

FrenchBreaches, a platform that tracks cyberattacks in France, said the incident affected about 678,437 people, equal to roughly 1% of the country’s population. That figure is still being investigated and has not been finalized.

Leaked records include identity and income details

The exposed data reportedly includes names, dates of birth, home addresses, phone numbers, email addresses, tax identification information and income data.

Among the affected records, nearly 27,000 people had taxable income of at least 100,000 euros. Another 386 were above 1 million euros, and eight were above 10 million euros.

Database reportedly listed for sale

The report said the database has been put up for sale on a dark web marketplace for several thousand euros.

The attacker identified itself as ZeroBytes and claimed it pulled the records using an internal search tool before the access was detected and cut off.

Crypto sector sees added physical security risk

The breach has raised concern in the crypto industry because violent wrench attacks against crypto holders have increased in France in recent years.

If high-income individuals’ addresses and contact details are exposed, the leaked records could give criminals a more precise list of targets.
