What happened
On May 20, 2026, United Medical Systems (DE), Inc. filed a data breach notification with the Maine Attorney General disclosing that an unauthorized party accessed limited files on its network on December 19, 2025. The company discovered the incident and, after retaining third-party cybersecurity specialists, completed its investigation on May 13, 2026, approximately five months after the unauthorized access.
According to the public filing, the affected files contained patient names along with other data elements that were not specified in the notice. UMS states that it immediately secured its network, implemented additional cybersecurity safeguards, and notified affected individuals with instructions to enroll in complimentary identity-protection monitoring services. The duration and monitoring provider were not disclosed in the public notice.
United Medical Systems provides mobile medical services and advanced urological care solutions across North America. Because the company handles patient health information, the incident may implicate obligations under HIPAA and applicable state breach notification laws. The full scope of data categories involved has not been publicly confirmed.
