Broadband ISP Demon Internet UK (THUS Group) has accidentally released a confidential Spreadsheet - containing details of 3,600 customer email addresses, telephone numbers, usernames, passwords and more - into the public domain.

The information was reportedly attached as a file to an email that had been intended to educate customers about the provider’s new eBilling system. It's understood that several thousand users received the same message, specifically those who signed up to the ISPs new paperless billing system.


It's probably a good time to inform users that Demon currently has a 'Customer Satisfaction Survey' running, which can be found - HERE. Demon's broadband customer base has recently been in decline and we suspect that this latest blunder probably won't help that situation.
