Cyberattack on Kuujjuaq Health Centre Exposes Clinical Records in 2025 Breach The Ungava Tulattavik Health Centre (UTHC) in Kuujjuaq disclosed a cyberattack in November 2025, revealing that sensitive clinical and administrative records may have been compromised. Initially believed to have caused no data exposure, further analysis confirmed that files containing patient and employee information were potentially accessed by malicious actors. UTHC detected the attack promptly, isolating the breach and securing its network. The health centre has since established a crisis unit, deployed enhanced surveillance tools, and notified financial institutions and local authorities. A joint investigation is underway with Québec’s Cyber Defence Operational Centre (CDOC), the Sûreté du Québec, and the Nunavik Regional Board of Health and Social Services (NRBHSS). Officials described the incident as a "major" attack, likely carried out by organized cybercriminal groups. UTHC has set up dedicated support channels for affected users and employees, including email and phone contacts for inquiries. While the full scope of the breach remains under review, the health centre has emphasized its commitment to transparency and data protection.
