Humber River Hospital in Toronto was hit with a ransomware attack in June 2021.
The hospital system immediately shut down its all IT systems , including our patient health records system.
The hospital had over 5000 computers (800 of which are servers) each were to be restarted manually; the patch (just developed by Symantec) was to be added to each computer and then each system recovered as required.
They also had to cancel a variety of clinics and re-directed impacted patients, the Emergency Department was still open but the ambulances were redirected.
