The province is estimating as many as a hundred-thousand of its employees may have been affected by an attack on the file-sharing system MOVEit, including employees of the Health Authority, the IWK and the public service.
Cyber Security Minister Colton LeBlanc says the information stolen includes social insurance numbers, addresses and banking information.
LeBlanc isn’t saying if, or how many, people outside government have been affected.
The province says it will be offering free credit monitoring to those affected and those people will be contacted over the coming weeks.
Microsoft is blaming the attack on a ransomware group called Clop but LeBlanc isn’t commented on the claim.
The province says the system went back online yesterday afternoon and additional security updates and monitoring have been installed.
An investigation continues, and updates and information can be found online at novascotia.ca/privacy-breach.
