ISP Emails Customer Database To Thousands

British ISP Demon Internet has mistakenly sent out a spreadsheet containing the personal details of more than 3,600 customers with one of its new ebills. The spreadsheet contains email addresses, telephone numbers and what appears to be usernames and passwords for the ebilling system. It was attached to an email explaining how to use the new system. Police forces and NHS trusts are among the email addresses listed in the database. A spokesman for Demon Internet confirmed that the company "was aware this happened this morning".
