Dominos Pizza are being held to ransom by hackers who say they have stolen the details of more than 600,000 customers.
The US fast food giant has fallen victim to blackmailers who are demanding 30,000 euros (£24,000) or they will publish the details of customers in Belgium and France.
The data stolen includes customer names, delivery addresses, phone numbers, email addresses and passwords.
Domino’s Vice President of Communications Tim McIntyre said the hacking was “isolated” to independent franchise markets of Belgium and France, where the company’s online ordering system not collect credit card orders, so no financial data had been taken.
“This does not affect any market outside of France and Belgium,” he said. “The site has been secured.” Domino’s has some 11,000 stores worldwide, including 229 in France, 24 in Belgium and about 5,000 in the United States.
A Tweet directed at Domino’s customers through an account of “Rex Mundi” said hackers would publish the customer data on the internet unless the company pays up, but the account was later suspended.
A Dominos spokesman said the company would not be making any such payment.
