Threat Risk: High
Victim: Health Sciences Centre (HSC)
Incident: Ransomware attack disrupting building management systems.
Impact: Loss of control over hospital doors, elevators, and HVAC systems.
Attacker: Unidentified threat actors
Analysis: The attack on Winnipeg’s Health Sciences Centre highlights a dangerous shift toward targeting Operational Technology (OT) within healthcare settings. By disrupting building management systems, attackers demonstrated the ability to interfere with critical physical facility operations. While patient care persisted, the breach underscores the severe risk associated with converged IT/OT environments.
