Canada’s largest pediatric health center suffered a recent cybersecurity incident that exposed the personal information of current and former employees. 

The Hospital for Sick Children — which was hit in a ransomware incident in 2022 that disabled some of its systems — released a statement on Thursday warning of a data theft incident they believe is tied to a third-party software application.

The recent cyberattack briefly took down the careers website for the hospital, which is known colloquially as SickKids, prompting it to begin an investigation. 

SickKids did not respond to requests for comment about when the attack occurred but said in a statement that investigators believe the hackers likely stole information related to current and former employees as well as job applicants and employees of related organizations, including the SickKids Foundation.
