Medical Express Ambulance Service
Medical Express Ambulance Service in Skokie, Illinois, has recently issued notification letters to individuals affected by a cybersecurity incident that was detected more than a year ago. While not specifically mentioned, the language used indicates this was a ransomware attack. The security breach was identified on March 18, 2024, when network disruption was experienced that affected the functionality of certain systems. Third party cybersecurity experts were engaged to investigate and confirmed that the threat actor had access to systems where patient data was stored and could therefore have acquired patient information.
Legal counsel for Medical Express confirmed that the data mining process was completed on January 30, 2025, and a mailing vendor was engaged on March 3, 2025. The final list for notifications was obtained on March 19, 2025, and the notification letters were mailed on April 14, 2025. The data potentially obtained by the threat actor included names, demographic information, dates of birth, Social Security numbers, driver’s license numbers, medical information, financial information, health insurance information, usernames and passwords, and for some individuals, passport numbers. Medical Express said it is unaware of any misuse of the affected information, but as a precaution, the affected individuals have been offered 12 months of credit monitoring and identity theft protection services.

Newport Harbor Pathology Medical Group
Newport Harbor Pathology Medical Group, which includes Orange County Medical Group Pathology, Mission Laguna Pathology Medical Group, and Barr Dermatopathology, has recently notified the California Attorney General about a security incident detected on November 11, 2024.
Unauthorized activity was identified in part of its network and third-party cybersecurity experts were engaged to investigate the activity. Their investigation confirmed that a threat actor had access to its network from October 8, 2024, to November 11, 2024, and potentially viewed or copied files containing patient data. A comprehensive review of all files on the network confirmed that the exposed information included names, Social Security numbers, dates of birth, addresses, diagnoses, pathology test results, medical record numbers, driver’s license numbers, unique or other government-issued identification numbers, and health insurance information.
Steps are being taken to improve security to prevent similar incidents in the future and the affected individuals have been offered complimentary credit monitoring and identity restoration services for 12 months. The breach is not yet shown on the HHS’ Office for Civil Rights breach portal, so it is currently unclear how many individuals have been affected.
Rhea Medical Center
Rhea Medical Center in Dayton, Tennessee, has announced that it was one of the healthcare providers affected by a data breach at the debt recovery firm Nationwide Recovery Service. The debt collection agency identified suspicious activity within its network in July 2024, which caused a network outage.

The information stolen in the incident included names, addresses, Social Security numbers, financial information and medical information.
