Kettering Health Data Breach Exposes Social Security Numbers & Health Info

On May 20, 2025, Kettering Health discovered suspicious activity in its network that led to the exposure of sensitive information belonging to current and former patients, as well as affiliates.

The unauthorized access occurred between April 9 and May 20, 2025. During this period, cybercriminals infiltrated Kettering Health’s network, viewing and potentially taking files and folders without authorization. The incident resulted in a system-wide outage that disrupted hospital operations, canceled procedures, and impacted call center services.

The breach exposed a range of personally identifiable information (PII) and protected health information (PHI) including names, contact information, Social Security numbers, patient identification numbers, medical record numbers, medical information, treatment information, diagnosis information, health insurance information, driver’s license or state identification numbers, financial account information, education records, and dates of birth.

Kettering Health has not disclosed the total number of individuals affected, but the scope of the breach, which spans over a month and impacting both PII and PHI, makes this a severe incident.
