Canada Post, the primary postal operator in Canada, has informed 44 of its large business customers that some information was compromised as a result of a malware attack at a supplier.
The impacted supplier is Commport Communications, an electronic data interchange provider that Canada Post uses to manage shipping manifest data for large parcel business customers.
Canada Post said it learned about the data breach on May 19, but its IT subsidiary, Innovapost, was informed in November 2020 that there had been a ransomware attack on Commport.
According to Canada Post, the attackers gained access to shipping manifests, which are used to fulfill customer orders and which typically include contact information for the sender and recipient.
An investigation conducted by the organization revealed that the information of more than 950,000 receiving customers was stored in the compromised shipping manifests.
"We are proactively informing the impacted business customers and providing the information and support necessary to help them determine their next steps. As well, the Office of the Privacy Commissioner has been notified," Canada Post said.
