On September 19, 2025, the California Department of Industrial Relations (“DIR”) reported a significant cybersecurity incident to the California Attorney General’s Office. The incident, which occurred from August 26 through September 2, 2025, involved unauthorized access to DIR’s public works contractor registration system (the “Data Breach”). During this time, sensitive personal data of contractors and others who used the system may have been viewed or downloaded by an unauthorized third party. Recently, DIR has begun sending data breach notification letters to those affected.
