Security News > 2023 > February > California medical group data breach impacts 3.3 million patients
Multiple medical groups in the Heritage Provider Network in California have suffered a ransomware attack, exposing sensitive patient information to cybercriminals.
The entities collectively issued a notice of data breach at the start of the month and shared a sample letter with the California Attorney General's office earlier this week.
Today, the healthcare organization reported on the U.S. Department of Health and Human Services breach portal that the data of 3,300,638 patients was exposed in the attack.
The data breach notification says the ransomware attack occurred on December 1, 2022, with Regal's employees noticing technical difficulties the following day.
Ransomware actors steal this data to create further leverage when extorting healthcare organizations, taking advantage of the highly sensitive nature of medical data.
Impacted patients should look out for targeted phishing attacks, scams, social engineering, or extortion using stolen data.
