Internet service provider (ISP) Be Broadband has slipped up by inadvertently leaking hundreds of private email addresses belonging to former customers.
The broadband provider issued a group email to ex-subscribers requesting the return of their wireless routers following cancellation – as stipulated in their contract.
However, the firm accidentally used the To: email field rather than Bcc: when sending the reminder, meaning the private addresses were left unencrypted and visible to other recipients, reports ISPreview.co.uk.
A Be Broadband statement read: "You may have received an email from our company regarding the return of the Be Box modem. Due to an error, you may be able to see the email address of other Be customers."
The ISP assured customers that no other personal information was visible to the recipients of the message.
"[We] would like to express our sincere apologies for any inconvenience caused," Be Broadband stated.
According to the news provider, some customers have complained to the broadband provider about the information leak.
