Nacogdoches Memorial Hospital 2026 Patient Data Breach

Nacogdoches Memorial Hospital, an independent Texas healthcare system comprising an emergency-capable facility, multiple provider practices, and a rehabilitation center, experienced a data breach discovered in January 2026 and publicly disclosed in April 2026. The incident exposed the personal information of 257,073 patients through unauthorized access by external threat actors.

The breach involved hackers gaining access to sensitive patient data, though the specific initial access vector and exploitation techniques remain unspecified. The compromised information includes comprehensive patient personal data, though the exact data types and formats were not detailed in the available reporting. No threat actor attribution or specific ransomware group involvement was confirmed.

The hospital has completed breach notification procedures to all affected individuals, fulfilling regulatory requirements for healthcare data breaches under HIPAA regulations. The three-month gap between discovery and public disclosure suggests internal investigation and forensic analysis preceded the formal announcement.
