LACMA Faces Class-Action Lawsuit Over 2025 Data Breach
A class-action lawsuit has been initiated by a former worker of the Los Angeles County Museum of Art (LACMA) in California’s Superior Court, following a significant data breach that occurred from July 7 to 11, 2025. The breach exposed sensitive information, including Social Security numbers, affecting both staff and visitors. Adam Piron, who was employed at LACMA between 2018 and 2020, alleged that the museum delayed informing employees about the breach for almost a year, with the issue only surfacing in June 2026. The lawsuit seeks damages and enhanced security protocols, while LACMA acknowledges the breach and is engaging cybersecurity professionals.
