Cookeville Regional Medical Center Data Breach Exposes Sensitive Patient Information
On March 16, 2026, Cookeville Regional Medical Center in Cookeville, Tennessee, concluded its investigation into a data breach that compromised highly sensitive patient information. The incident, detected on July 14, 2025, revealed that an unauthorized party accessed and potentially exfiltrated files containing personal and medical data between July 11 and July 14 of that year.
The exposed records included names, addresses, dates of birth, Social Security numbers, driver’s license numbers, financial account details, medical treatment information, medical record numbers, and health insurance policy details. The hospital partnered with a forensic security firm to confirm the breach and assess its scope.
Cookeville Regional has since begun notifying affected individuals, though legal professionals are also investigating the possibility of a class action lawsuit on behalf of those impacted. The breach raises concerns about potential financial fraud, identity theft, and long-term privacy risks for patients. No further details on the attackers’ identity or motives have been disclosed.
