Loblaw is investigating a data breach after detecting suspicious activity on a contained, non-critical part of its IT network. The Canadian retailer said a third party accessed limited customer information, including names, phone numbers and email addresses, but passwords, health data and credit card details were not compromised. Loblaw has notified affected customers, logged users out of its digital services as a precaution, and said the incident did not impact its PC Financial unit or its expected financial performance.
