Key Numbers
What Happened
France's tax authority DGFiP suffered a data breach affecting 678,437 taxpayer records. An attacker used stolen VPN credentials to access an internal search tool in late June. The intruder extracted names, contact details, tax identifiers, income figures, withholding rates, and family information before administrators cut access. DGFiP confirmed the intrusion. Cybersecurity outlet FrenchBreaches first reported the incident. The leaked database contains records on 392,867 individuals and 285,570 professionals. The hacker is selling the data for several thousand euros. The exposure creates a credible attack vector for scammers targeting wealthy taxpayers and Bitcoin holders.
The Numbers
The breach exposed 678,437 records: 392,867 individuals and 285,570 professionals. Among those, 26,805 reported reference tax income of at least $116,000, while 386 exceeded $1.16 million and eight surpassed $11.6 million. The hacker lists the database for several thousand euros. Stolen VPN credentials enabled access in late June. FrenchBreaches confirmed DGFiP acknowledged the intrusion. The number of affected people remains under investigation. These figures underline the scale of personal financial data now circulating on criminal forums.
Why It Happened
The attacker leveraged stolen VPN credentials and an internal DGFiP search tool to extract taxpayer data. This breach fits a pattern of criminals targeting high-net-worth individuals, especially Bitcoin holders. Wrench attacks have surged in France, with CertiK reporting 52 worldwide in H1 2026, 33 in France. Chainalysis counted 46 attacks through June, 30 in France, with $30 million stolen. The leaked tax data makes phishing and social engineering far more convincing, enabling scammers to reference real income figures and tax details.
Broader Impact
The breach underscores the vulnerability of centralized databases holding sensitive financial data. For Bitcoin holders, the risk is not just digital but physical: wrench attacks use violence to steal crypto. This incident may push privacy-conscious users toward self-custody and enhanced opsec. It also highlights the need for stronger protections around government-held financial data, as criminals increasingly combine digital and physical threats.
What to Watch Next
- DGFiP's investigation into the total number of affected individuals.
- Potential phishing campaigns using stolen tax data.
- Increased reports of wrench attacks targeting crypto holders in France.
