Patient Data Potential Compromise Due to Ransomware Attacks on Monterey Health Center and Magnolia Pediatrics

The investigation findings uncovered no evidence of data exfiltration, yet unauthorized data access could not be completely eliminated. So far, there are no information received concerning the misuse of any patient data.

The informatioin likely exposed included: patient names, birth dates, addresses, Social Security numbers, driver’s license numbers, medical histories, diagnoses information, laboratory test findings, treatment details, prescribed drugs, medical insurance information, claims records, and financial account information.

Monterey Health Center sent notifications to all persons affected by the breach and gave instructions on improving their security. Third-party professionals, alongside the health center, will not stop in making sure that the systems and records of the patients medical and personal information cannot be accessed by unauthorized persons.
