The statement from Bell:
Hackers illegally accessed some customer information, including name, email address and in some cases phone number, user name and/or account number, for a limited number of Bell customers. There is no indication that any credit card or other banking information was accessed.
We apologize to our customers and are contacting all those affected. There is an active RCMP investigation of the incident and Bell has notified appropriate government agencies including the Office of the Privacy Commissioner.
Bell works closely with law enforcement, government and the broader technology industry to combat the growth of cyber crimes, and we have successfully supported law enforcement in past prosecutions of hackers.
