In a warning posted at the weekend, the group said that it had gained access to over 592,000 customer records from French customers and over 58,000 records from Belgian ones, and will release this at 8pm CET (7pm BST) if its demands are not met.
The group claims to have downloaded a large number of customer records, including their full names, addresses, phone numbers, email addresses, passwords, delivery instructions and even their favourite toppings.
Domino’s confirmed that customer records have been breached, but said that financial information is not at risk. However, customers are being advised to change their passwords.
The pizza delivery franchise has no plans to meet the group’s demands.
