The Hospital for Sick Children (SickKids), Canada's largest paediatric health centre and a 2022 ransomware victim, disclosed a data-theft incident it believes is tied to a third-party software application. The attack briefly took down its careers website; investigators believe hackers likely stole information on current and former employees, job applicants and staff of related organisations including the SickKids Foundation, and the incident did not involve clinical systems or patient information. Affected individuals have been offered two years of credit monitoring.
