Canada Post Reports Data Breach Following Cyberattack

Canada Post says the shipping data of more than 40 of its large commercial customers has been compromised following a cyberattack.

Canada Post said that data exchange solutions provider Commport Communications notified it last week of a data breach caused by a malware attack.

The attack compromised the shipping manifest data associated with 44 business clients, containing the information of more than 950,000 mail recipients.

Shipping manifests typically include the sender and receiver contact information that’s found on shipping labels, such as names and addresses. The compromised information dates back to July 2016.

Canada Post said an investigation into the attack provided no evidence that any financial information was breached. The Crown corporation said it’s working closely with Commport and external cybersecurity experts to decide what further actions to take.

Commport had previously notified Canada Post of a ransomware attack last fall. A probe into the matter found no evidence customer data had been compromised in that attack.
