KH Credit Union Data Breach Exposes Social Security Numbers

KH Credit Union, a not-for-profit credit union based in the Dayton, Ohio area that serves Kettering Health employees and their families, disclosed a data breach involving member information that was stored on Kettering Health's network. The total number of people affected in the United States was not disclosed.

The breach was reported to the Massachusetts Office of Consumer Affairs and Business Regulation on June 16, 2026. The credit union also posted a notice on its website regarding the incident.

On or about May 20, 2025, Kettering Health became aware of suspicious activity affecting certain systems within its network. Kettering Health took steps to secure its environment and launched a comprehensive investigation with the assistance of third-party cybersecurity specialists.

The investigation determined that there was unauthorized access to Kettering Health's environment between April 9, 2025, and May 20, 2025. During that time, certain files and folders within the network were potentially viewed or acquired without authorization.

The incident did not involve KH Credit Union's own network and was limited solely to Kettering Health's systems.

The types of personally identifiable information and protected health information exposed included full names, Social Security numbers, bank and/or financial account numbers, driver's license and/or state identification numbers, medical billing and/or claims information and patient account numbers.
