California Medical Group data breach affects 3.3 million patients
Multiple medical groups at Heritage Provider Network in California suffered a ransomware attack, exposing sensitive patient information to cybercriminals.
The medical groups affected by the cyber attack are Regal Medical Group, Lakeside Medical Organization, ADOC Medical Group and Greater Covina Medical.
The companies jointly released a data breach notification earlier this month and shared a sample letter with the California Attorney General’s Office earlier this week.
Today, the health organization reported on the breach portal of the US Department of Health and Human Services that the data of 3,300,638 patients were exposed in the attack.
