Eastlink Alerts Customers to Potential Data Breach Affecting Personal Information
Eastlink, a telecommunications provider serving seven Canadian provinces and Bermuda, has notified customers of a potential data breach that may have exposed sensitive personal information. The company disclosed that unauthorized access to accounts occurred between late Wednesday and early Thursday morning.
Affected data may include customer names, contact details, account numbers, and PINs. However, Eastlink stated that credit card or banking information was not compromised. The exact number of impacted individuals remains unclear.
Former customer Caitlyn Horne of Halifax, who terminated her service in 2023, received the breach notification, suggesting the incident may extend to historical account holders. Horne expressed concern over the breadth of exposed data, emphasizing the need for greater transparency and support, such as credit monitoring, for affected users.
In response to the incident, Eastlink apologized and took immediate action by shutting down affected platforms on its website and mobile app. The company is currently investigating the breach, with spokesperson Jill Laing indicating that further details would be shared after Monday.
The incident highlights ongoing cybersecurity risks in the telecommunications sector, with customers left uncertain about the full scope of the exposure.
