A RIB, short for Relevé d’Identité Bancaire, is a French bank identity document used in financial paperwork. It identifies the account holder and the bank account details needed to receive or send payments, often alongside identifiers such as IBAN and BIC. In practice, a RIB is not a password, but it is still sensitive financial data because it can be used to route transfers or support identity verification.
In cyber security, leaked RIBs matter because they can help attackers build convincing phishing, payroll diversion, and vendor-fraud scams. A criminal who knows an employee’s bank details may use them to fake a payment update or combine them with other stolen records for impersonation. Defenders should treat RIBs as regulated personal and financial information: limit access, log retrieval, redact documents where possible, and monitor for unusual requests to change payment coordinates.
