French Tax Authority Data Breach: 678,000 Hit

**French Tax Authority Data Breach:** DGFiP confirmed unauthorized access in June–July 2026 that exposed sensitive tax and financial records for about 678,000 individuals and companies via compromised or impersonated employee and third-party credentials; DGFiP reports that taxpayer account passwords were not compromised, CNIL and ANSSI have been notified, and investigations and remediation are ongoing. The breach raises elevated risks of targeted phishing, identity fraud, invoice and supplier scams, and social‑engineering attacks despite the absence of published technical IoCs.
