Ontario Secondary School Teachers' Federation

Ontario Secondary School Teachers’ Federation fell victim to a ransomware attack after an unauthorized third party compromised members’ personal information.

The union hired a cybersecurity firm to “contain” the incident, as well as investigate the scope and nature of the information accessed.

The union informed the members whose personal information such as addresses and social insurance numbers, was involved in the breach.
