Canada’s largest school board says systems are operational after cyber attack

TORONTO — Canada’s largest public school board says it is working with police to assess the impact of a recent cyber attack, but its main system remains operational and was not affected.

In a letter to parents, the Toronto District School Board says an unauthorized party gained access to its technology testing environment, which is segregated and used to test programs before they run on the board’s main computer system.

The council says its cyber security team has taken immediate steps to secure and preserve data and protect critical systems.

The TDSB says it is conducting a thorough investigation to understand the nature of the incident, any impact on its network and whether any personal information in the test environment may have been affected.

It says the province’s privacy commissioner has been notified and affected individuals will be contacted if there has been an impact on personal information.

The council says it can only provide limited information about the incident due to the ongoing investigation, but parents can get in touch if they have any questions.
