Download Our Cyber Insights Document on France's National Bank Account Registry Data Breach
A Credential Compromise That Exposed 1.2 Million Financial Records - In February 2026, France’s national bank account registry (FICOBA), a core component of the country’s financial oversight infrastructure was compromised through a single internal credential. The breach exposed approximately 1.2 million bank account records, including account holder names, account numbers, postal addresses, IBAN/RIB details, and in some cases taxpayer identifiers.
There was no confirmed ransom demand. But the implications are far more strategic than financial loss alone.
FICOBA is not a single bank. It is a centralised national registry of banking and financial accounts used for regulatory, tax, and oversight purposes. When a commercial bank is breached, the impact is contained within that institution. When a national registry is accessed, the impact spans multiple financial institutions, millions of individuals and businesses, regulatory confidence and national financial infrastructure trust.
