Monongalia Health System

Monongalia Health System, also known as Mon Health, is a health system headquartered in the United States of America. As a health system, it provides medical care and related services to patients within its service area. The organization operates facilities that deliver inpatient, outpatient, and emergency care. Its core mission centers on promoting health and treating illness for the communities it serves.

The organization’s scale and specific market reach are not detailed in the available sources, so quantitative metrics such as number of hospitals, beds, or employee count are omitted. Nevertheless, its designation as a health system indicates a multi‑facility structure that likely serves a regional population. Mon Health has been subject to regulatory oversight typical of U.S. healthcare providers, including compliance with health information privacy standards.

In December 2021, Monongalia Health System experienced a cyberattack that disrupted IT systems and potentially exposed personal and health‑related data of patients, employees, providers, and contractors, while electronic health records remained secure. The intrusion persisted for nearly two weeks, leading to data exfiltration and prompting the organization to isolate affected systems, reset credentials, enhance network defenses, and notify affected individuals.

Earlier in May 2021, a phishing campaign compromised several email accounts at the West Virginia hospital system, enabling unauthorized access over multiple months and leading to an investigation triggered by a vendor‑reported missing payment. Although the primary goal was financial fraud, the breach exposed sensitive patient, provider, employee, and contractor information, resulting in secured accounts, law‑enforcement involvement, forensic analysis, and subsequent notifications to impacted individuals.
