ERHC Data Breach Affects Patient Info

Emergency Responders Health Center (ERHC), a specialized medical provider for first responders, experienced a cyberattack. On April 11, 2025, the healthcare organization discovered suspicious activity within its email network. An investigation was launched and it was determined that several email accounts were compromised by an unauthorized actor between Dec. 11, 2024, and April 11, 2025.

This type of data breach often compromises both personally identifiable information (PII) and protected health information (PHI). In addition to names, exposed information may include addresses, dates of birth, Social Security numbers, driver's license copies, health insurance information, medical records and payment information.

Emergency Responders Health Center published a Notice of Data Security Incident on its website on July 23, 2025. The investigation was completed on Sept. 16, 2025 and the medical group began notifying impacted individuals by mail on Sept. 26, 2025.

The total number of affected individuals has not been released but is believed to include both current and former patients. ERHC disclosed the data breach to the Montana Attorney General's office and the Washington Attorney General on Sept. 26, 2025.
