Investigation notes
The Workers Compensation Insurance Rating Bureau of California (WCIRB) functions as an insurance industry organization that collects and manages extensive data related to workers' compensation policies and claims. Given the nature of their operations, they typically store highly sensitive information, including Social Security numbers, employment records, detailed medical histories, and specific insurance policy information. In 2025, the organization officially reported a data breach to the California Attorney General, confirming that unauthorized access to their systems occurred. If you have received a formal data breach notification letter from the WCIRB, it indicates that your personal or sensitive employment-related information may have been compromised. This notification is intended to inform you of the incident and provide guidance on the steps you should take to protect your identity.
