Ransomware Attack Disables Canadian Hospital’s Doors, HVAC

A ransomware attack on a Canadian hospital's facility management systems disabled doors and HVAC equipment, raising concerns about operational technology vulnerabilities in healthcare settings. The incident affected Manitoba, Ontario's largest hospital in Winnipeg and demonstrates expanding cyber threats targeting building infrastructure.

Why it matters: Healthcare facility operators and security teams need immediate visibility into OT systems controlling physical access and environmental controls, as these attacks now disrupt patient safety and care continuity.
