Coos County Family Health Services, a New Hampshire-based healthcare provider, suffered a ransomware attack in July 2025, where an unauthorized actor infiltrated its internal network and exfiltrated sensitive patient data. The breach exposed personally identifiable information (PII) and protected health information (PHI) including names, dates of birth, contact details, Social Security numbers, medical IDs, and clinical records of 40,185 current and former patients. The Run Some Wares ransomware group claimed responsibility, posting stolen data on a dark web forum. The incident triggered regulatory disclosures to the U.S. Department of Health and Human Services, as well as notifications to affected individuals in New Hampshire, Maine (1,222 residents), and Massachusetts (365 residents). The organization responded by securing systems, engaging law enforcement, and offering 12 months of free credit monitoring and identity protection services to victims. The breach poses risks of identity theft, financial fraud, and targeted phishing attacks leveraging exposed health and personal data.
