Mon Health, a healthcare organization serving patients in West Virginia, has reported a phishing-related data security incident that may have exposed sensitive personal and health information. Publicly available details about the incident remain limited.
Healthcare providers that maintain both personal and medical information for patients are expected to take reasonable steps to secure that information against unauthorized access, including protecting employee email accounts from phishing attacks.
Mon Health’s Data Breach Investigation
According to available regulatory filing information, Monongalia County General Hospital Company, doing business as Mon Health, reported a phishing-related incident with a reported incident date of May 6, 2026. The limited information available indicates the incident involved unauthorized access to email accounts and the information contained within them.
A complete public copy of Mon Health’s official notice letter is not currently accessible, so this summary is based on available filing information rather than a full public notice. The materials reviewed do not clearly state when the incident was discovered, when notice letters were mailed to affected individuals, or how many people were affected by this specific 2026 incident.
Mon Health has not publicly disclosed further detail about how the phishing attack succeeded or what remediation steps it has taken beyond what is reflected in the limited filing data currently available. This page will be updated if additional information becomes public.
Phishing attacks remain one of the most common ways healthcare organizations experience a data security incident, because a single successful phishing email can give an attacker access to an employee’s inbox and any patient information stored or transmitted through it. Healthcare email accounts are a frequent target because they often contain a mix of identity information, treatment details, and insurance data in one place, making them valuable to cybercriminals.
When Social Security numbers, dates of birth, and health information are exposed together, affected individuals can face risks beyond ordinary identity theft, including medical identity theft and health insurance fraud, where a criminal uses someone else’s health insurance information to obtain medical services or prescriptions. Because health information can’t be changed the way a password or credit card number can, exposure of this kind of data can create risks that persist well beyond the initial incident.
When Did This Breach Occur?
Available filing information reports the incident date as May 6, 2026. Mon Health has not publicly disclosed when the incident was discovered internally or when notice letters were sent to affected individuals.
What Information Was Breached?
Based on available filing information, the categories of information that may have been involved include names, Social Security numbers, dates of birth, health records, and health insurance information. It is not yet clear from public materials whether every affected individual had all of these data types exposed, or whether the specific mix varies by person. Individuals who receive a notice letter from Mon Health should review it for details specific to their own information.

If you believe you may have been affected by this incident, consider taking the following steps:
- Watch for an official notice letter from Mon Health and keep a copy if you receive one.
