A ransomware attack hit facility maintenance systems at Health Sciences Centre in Winnipeg, disrupting building operations including door access and heating, ventilation, and air conditioning (HVAC) controls. Shared Health, which oversees the hospital, said patient care and clinical operations continued uninterrupted and that there was no indication patients were affected. The organization said the incident appeared limited to those systems and that no other hospital systems were known to be impacted.
Shared Health said it launched an investigation into the nature and scope of the attack, notified the Manitoba government, and brought in expert assistance to respond. Reporting on the incident highlighted the growing risk ransomware poses to operational technology in healthcare environments, where attacks can disrupt physical infrastructure even when core clinical systems remain online. The attack also follows earlier warnings from Manitoba’s auditor general that Shared Health needed stronger cybersecurity testing and training to improve its readiness for cyber incidents.
