AltaMed Health Services Corporation recently disclosed a cybersecurity incident that may have compromised sensitive employee information. The breach occurred in December 2025 and involved unauthorized access to certain computer systems. Affected individuals are now being notified and offered complimentary identity protection services.
AltaMed Health Services Corporation’s Data Breach Investigation
On December 14, 2025, AltaMed Health Services Corporation experienced a cybersecurity incident that limited access to certain computer systems. Upon discovering the issue, AltaMed immediately activated its incident response protocols, secured its systems, and worked to contain the incident.
The organization engaged cybersecurity experts to conduct a comprehensive investigation into the nature and scope of the breach. Law enforcement was also notified. Despite the disruption, AltaMed remained operational and continued providing care to patients during the incident response process.
Following its investigation, AltaMed determined that certain personal employment information may have been accessed by an unauthorized individual. Although the company has not publicly reported confirmed misuse of the information, unauthorized access to employee data can pose significant risks, particularly when sensitive identifiers are involved.
AltaMed has stated that protecting the confidentiality, privacy, and security of personal information is among its highest priorities. In response to the incident, the organization implemented additional technical safeguards and monitoring tools to further secure its systems and reduce the likelihood of similar events occurring in the future.
Healthcare organizations often maintain extensive personal and employment-related information, making them frequent targets for cyberattacks. When sensitive data is accessed by unauthorized actors, affected individuals may face long-term risks—even if no immediate fraud is detected.
At Class Action U, we believe individuals deserve transparency and accountability when organizations fail to adequately safeguard sensitive data. If your personal information was exposed, you have the right to understand your legal options.
