France's DGFiP said that from late January 2026 a malicious actor used the stolen credentials of an official with inter-ministry access to consult the FICOBA file, which lists all bank accounts opened in France [1]. Access was immediately restricted; the data consulted or extracted is estimated to involve 1.2 million accounts, tax identifiers were not consulted, and the finance ministry contacted banks to urge customers to be vigilant [1][2]. The tax authority never asks for credentials or card numbers by message; verify suspicious messages by contacting your tax office via your account's secure messaging or by phone [1].
