A ransomware attack impacting five hospitals in southwestern Ontario, Canada, has seen hackers gain access to a database containing 5.6 million patient visits, and the social insurance numbers of over 1400 employees. The attack against IT service provider TransForm, which took place on October 23, resulted in outages in IT systems at Windsor Regional Hospital, Erie Shores HealthCare, Hôtel-Dieu Grace Healthcare, Bluewater Health and Chatham-Kent Health Alliance, leaving patients facing appointment delays and cancelled surgeries.
