The North Atlantic States Carpenters Health Benefits Fund has reported a significant cybersecurity incident affecting 501 individuals, according to breach notification records filed with the U.S. Department of Health and Human Services on October 17, 2025. This Massachusetts-based health plan experienced a hacking/IT incident that compromised member information stored on their network servers.

What Happened

The North Atlantic States Carpenters Health Benefits Fund, which provides health insurance coverage to union members and their families, suffered a cyberattack that targeted their network infrastructure. The breach was classified as a hacking/IT incident, indicating that unauthorized individuals gained access to the organization's computer systems.

While specific details about the attack methodology remain limited in public disclosure documents, the incident affected the health plan's network servers where member information was stored. The breach was reported to federal authorities on October 17, 2025, in compliance with HIPAA breach notification requirements under 45 CFR §164.408.

Who Is Affected

The cybersecurity incident impacted 501 individuals who are members or beneficiaries of the North Atlantic States Carpenters Health Benefits Fund. This includes:

• Union carpenters covered under the health plan
• Spouses and dependents of covered members
• Retirees who maintain coverage through the fund
• COBRA beneficiaries and other eligible participants

As a covered entity under HIPAA, the health plan is required to protect all protected health information (PHI) in accordance with the Privacy Rule (45 CFR §164.502) and Security Rule (45 CFR §164.306).
