California Columbia Bank Breach: What Victims Need to Know

Columbia Bank officially reported a data breach to the California Attorney General on April 17, 2026, stemming from an incident that occurred on October 2, 2025. As a financial institution, the bank maintained records containing sensitive consumer data that digital attackers managed to access.
