French tax authority discloses massive data breach affecting 678,000 individuals, with personal data offered for sale online
Executive summary: 678,000 individuals had their tax‑related personal data stolen and subsequently offered for sale on illegal online marketplaces. The breach exposes victims to identity theft and financial fraud, undermines public trust in the tax administration, and triggers potential GDPR penalties for the French state.
Who is involved: French tax administration (DGFiP), the 678,000 affected taxpayers, and unidentified cybercriminals selling the data.
Likely next: DGFiP will launch a formal investigation with CNIL, issue breach notifications to victims by end of August, and may face regulatory fines; affected individuals are advised to monitor bank and credit accounts and consider identity‑protection services.

The agency urged those affected to monitor their accounts and remain vigilant against phishing and identity‑theft attempts. The incident highlights the growing vulnerability of government‑held data and raises immediate concerns about financial fraud and privacy rights.
