St. Lawrence Health System

St. Lawrence Health System operates a network of hospitals that includes Canton‑Potsdam Hospital, Massena Hospital, and Gouverneur Hospital. The organization delivers inpatient, outpatient, emergency, and specialty medical services to residents of the surrounding communities. As a health system, it coordinates care across its facilities to provide continuity for patients requiring multiple levels of treatment. Its headquarters is located in the United States, placing it within the U.S. healthcare sector. The system provides care to individuals living near its hospital sites. By offering a range of clinical departments, it aims to meet the diverse health needs of its service area.

In October 2020, St. Lawrence Health System experienced a ransomware attack that affected computers at its three hospitals. The incident involved a previously unseen variant of the Ryuk ransomware strain. Hospital officials publicly stated that no patient or employee data was compromised during the event. However, some observers expressed skepticism about the ability to confirm that no data had been exfiltrated, noting the attackers' potential to conceal such activity. The attack underscored the ongoing challenges healthcare organizations face in defending against sophisticated ransomware threats. Despite the cybersecurity incident, the health system continues to operate its facilities and provide medical care to the communities it serves.
