Shared Health: HSC Winnipeg Hit by Ransomware Attack Affecting Facility Maintenance Systems

Health Sciences Centre Winnipeg Hit by Ransomware Attack Targeting Facility Systems

The Health Sciences Centre (HSC) Winnipeg has confirmed a ransomware attack disrupting certain facility maintenance systems, including HVAC and door access controls. The incident was disclosed late Monday, with Shared Health stating that patient care and clinical operations remain unaffected urging those requiring medical attention to proceed as usual.

Investigations so far indicate no impact on patient data or safety, with clinical services continuing without interruption. Ransomware attacks involve encrypting files and demanding payment for their release, though HSC has not disclosed whether a ransom was requested.

HSC has launched a full investigation to assess the attack’s scope and origin, engaging third-party cybersecurity experts and notifying the Manitoba government and relevant partners. While the breach appears limited to non-clinical systems, the hospital is working to restore affected operations securely while maintaining care continuity. The incident remains under active review.
