Huron Regional Medical Center Ransomware Attack and Data Breach

552After Incident
CRITICAL-211
HUR1602516091125
On May 31, 2025, HRMC detected a cyber intrusion later attributed to the BEAST ransomware group, which exfiltrated 800GB of sensitive data, including PII (names, SSNs, financial accounts, addresses) and PHI (medical records, lab results, prescriptions, treatment histories, insurance details, and diagnostic images). The breach impacted at least 20 Montana residents, with broader exposure across multiple states. The attackers leveraged the Tor network to publicize the theft on the dark web (Aug. 21, 2025). HRMC confirmed the incident involved unauthorized access, data copying, and a ransomware demand, though the total victim count remains undisclosed. Affected individuals received 12 months of credit monitoring and fraud alerts, with HRMC establishing a dedicated support line. The breach poses severe risks of identity theft, financial fraud, and medical privacy violations, given the depth of exposed information.
