What Happened at Palomar Health Medical Group?

Palomar began an investigation after suspicious activity and a potential cyberattack were detected on its computer network on May 5, 2024. The company says affected systems were taken offline to contain any malware, and services were disrupted.

After Palomar Health Medical Group (PHMG) identified suspicious activity and took the affected systems offline, they launched an investigation into the nature and scale of the event. Patients were informed that some communication systems were down, and were subsequently advised to visit their physicians in person and to expect delays. Third-party cybersecurity specialists were hired to help investigate the incident and identify the source of the attack. Much is unknown at the moment of writing, and patients do not know whether or not any patient data was compromised.

The data security incident appears to be confined to Palomar Health Medical Group. The Palomar Health Healthcare District, which includes Palomar Medical Center Poway and Palomar Medical Center Escondido, was reportedly not affected.
