Summary
On June 27, 2025, Mosaic Life Care informed patients of a data security breach involving Oracle Health/Cerner, which was discovered after an unknown party claimed to possess stolen patient information. The breach, traced back to compromised credentials during data migration on Oracle Health/Cerner's systems, affected patient data such as Social Security numbers, treatment details, and insurance information. Although Mosaic's own systems remained secure, the incident underscores the vulnerabilities associated with third-party health technology providers and highlights the need for enhanced security measures in healthcare data management. Healthcare professionals must remain vigilant in addressing potential risks associated with data sharing and third-party services to protect patient privacy.
