Virgin Media has lost a CD containing the bank details of 3,000 customers.
A spokesperson at the television and broadband firm said the company was investigating the problem and looking into why the information ended up on an unencrypted disc. “We would normally send encrypted files by FTP,” he said.
Virgin Media said it had notified the Information Commissioner’s Office, as well as ensuring relevant fraud bodies were notified so that customer bank accounts would be closely monitored for illegal activity. “At this stage, we have no evidence the disc has fallen into the wrong hands,” the spokesperson said.
In a statement the company said: "This is an isolated incident which has affected a small number of our customers. We have been working with the Information Commissioners' Office on this matter and we are in the process of contacting all of the affected customers to ensure we meet our responsibilities and fully support them through this process.
“Customer privacy is of the highest important to us and we are undertaking a full review of our data protection policies and practices to ensure this matter does not occur again. We are very sorry this situation has occurred and for the inconvenience this has caused our customers."
Theft of unencrypted information has been in the headlines this week, after the NHS lost the details of 31,000 patients on seven unencrypted laptops.
Last week, Cotton Traders was reported to have lost the details of up to 38,000 customers following a hack of its website, but would not confirm whether the data was encrypted or not.
