France's tax authority (DGFiP) has confirmed a data breach affecting approximately 600,000 individuals and businesses, with stolen information including tax identification numbers, personal details, and for around 250 people, the actual contents of private messages exchanged with the authority. Affected parties are being notified and warned of potential follow-on attacks such as phishing and impersonation scams exploiting the stolen data. The incident is the latest in a series of significant cybersecurity breaches targeting French public sector organisations in 2025.
French Tax Authority Breach Exposes Financial Data on 680,000 Citizens
France's tax authority (DGFiP) has disclosed a data breach affecting approximately 680,000 individuals, after a threat actor used compromised employee and third-party credentials to access its systems in June and July. Stolen data includes reference tax income, withholding tax rates, company identifiers, and real estate cadastral data, though no passwords or usernames were compromised. The breach was reported to France's data protection authority CNIL, and DGFiP is contacting all affected individuals while continuing to investigate the full scope of the incident.
France's Tax Authority Confirms Data Breach After Hacker Hawks 2 Million Taxpayer Records Online
France's tax authority (DGFiP) has confirmed a data breach that occurred in late June 2026, in which an attacker using stolen credentials and an MFA bypass technique accessed and extracted data on approximately 2 million taxpayers. The alleged criminal, known as "ZeroBytes," advertised the stolen database on a cybercrime forum and claimed to still have access to DGFiP's systems, though the agency disputes this and says access was severed during a routine audit. The incident is one of several significant cyberattacks targeting French public sector organisations in 2026, following earlier breaches affecting the Finance Ministry, Health Ministry, and the passport and driver's licence agency France Titres.
