A UK finance company has exposed the e-mail addresses of 294 customers after sending them messages about late repayments.
Clode Retail Finance - which provides personal loans and retail and healthcare finance - e-mailed the customers on Monday to tell them they were behind with repayments and warning of impending legal action.
But the firm failed to hide the addresses, revealing to each recipient that the others were behind in their repayments.
Clode chief executive Nick Davies says "human error" was to blame for the privacy breach and internal procedures have now been changed.
However, according to legal newswire OUT-LAW.COM, at least one of the affected customers intends to report the breach to the Information Commissioner's Office, which oversees the Data Protection Act.
