Between February 18, 2025 and March 4, 2025, Oklahoma's CardioVascular Health Clinic (CHC) experienced a data breach. The incident began when an unauthorized individual accessed certain information stored on CHC’s network through a security incident involving their cloud services provider.
The breach was discovered after a network disruption on March 4, 2025, prompting an investigation with the assistance of third-party cybersecurity specialists.
While the exact number of affected individuals has not been disclosed at this time, the scope of the breach is extensive. The information potentially exposed includes a wide range of both personally identifiable information (PII) and protected health information (PHI).
PII that may have been accessed includes name, address, phone number, email address, date of birth, Social Security Number, driver’s license or state ID number, and financial account information. PHI potentially involved consists of treatment and diagnosis details, prescription information, provider name, medical record or case number, Medicare or Medicaid ID number, health insurance information, and treatment cost.
The breach is considered severe due to the sensitive nature of the data involved and the method of unauthorized access through a third-party cloud provider. This type of incident can increase risks of identity theft, financial fraud, and misuse of medical information.
