Manitoba Families was notified, on Friday, of a security breach to the Southern First Nations Network of Care’s computers.
Eight agencies, including the West Region Child and Family Services, were attacked by a virus targeting computer systems earlier in the week.
As soon as the province knew, steps were taken so the provincial systems and information were safe.
SFNNC and their agencies have put together contingency plans to continue their support and protection of the children and families in their care.
The province is offering technical support as well as other resources.
Due to the system being down, the agency will have to manually access information for 4000 children.
The extent of information that could be at risk is still being determined.
The Canadian Centre for Cyber Security is investigating.
