Virgin is now advising all those affected to be on alert with the firm advising the, given the nature of the information involved, there is a risk you might be targeted for phishing attempts, fraud or nuisance marketing communications.

Speaking about the security lapse, Lutz Schüler, chief executive of Virgin Media said: “We recently became aware that one of our marketing databases was incorrectly configured which allowed unauthorised access. We immediately solved the issue by shutting down access.”

“Protecting our customers’ data is a top priority and we sincerely apologise,” he said.

“Based upon our investigation, Virgin Media does believe that the database was accessed on at least one occasion but we do not know the extent of the access or if any information was actually used,”
