Orthopaedic Institute of Western Kentucky’s Data Breach Investigation
On January 15, 2026, the Orthopaedic Institute of Western Kentucky (OIWK) confirmed that a data breach occurred due to a cybersecurity incident involving Keystone Technologies, a third-party vendor that provided managed IT services to OIWK. The breach involved two separate incidents, one between April 21 and April 26, 2025, and another between July 19 and August 1, 2025. Unauthorized third parties gained access to certain computer systems hosted by Keystone Technologies and obtained files that contained sensitive patient information.
The breach was discovered during an investigation initiated by OIWK, with the assistance of an external forensic firm. The investigation revealed that the files involved in the breach contained personal and medical information, such as names, Social Security numbers, dates of birth, addresses, medical record numbers, health insurance details, and treatment information. Notably, OIWK’s own electronic medical record system, as well as Mercy Health’s IT and medical record systems, were not affected by the breach.
Although OIWK has not received reports of fraud or identity theft related to the breach, they are offering protection services to affected individuals to help prevent further risks.
