Domino’s Pizza recently found itself threatened with the release of hundreds of thousands of stolen accounts to the internet.

According to ITNews, a hacker group known as Rex Mundi had attempted to blackmail the Domino’s Pizza operations in France and Belgium with the release the account information of hundreds of thousands of customers.

Allegedly they had the account information from 592,000 French customers and 68,000 Belgian customers.

The customer information being held for ransom by the group includes the person’s name and address along with their telephone number, email address, and account password.

The group was demanding €30,000 or $40,600 USD.

Domino’s French Twitter account admitted that it was likely the hackers had the information and that a breach had occurred.

The group was referred to as “seasoned professionals”. Even though the information was encrypted, Domino’s believes Rex Mundi probably had the ability to decode the information, passwords included.

Rex Mundi’s own Twitter account has since been suspended.

A spokesman for Domino’s tried to allay their customers’ fears by confirming that no banking or financial information was accessed by the hackers. That is because Domino’s does not hold on to payment information. Due to the way customer data is stored, names, phone numbers, and email addresses are the most vulnerable to hackers.

Despite the ensuing headache, Domino’s Pizza have opted not to give into the blackmail attempt. Instead the company alerted the French authorities.

Domino’s Pizza is the latest company targeted by Rex Mundi. The group previously released thousands of customer loan records after Americash Advance refused to pay them $15,000. They also attempted to blackmail a Belgian hosting firm named Alfanet.

Though Domino’s has confirmed that it’s likely these individuals were able to get the information they hold, it’s not known how many customer account details Rex Mundi will release since they are unlikely to get their money.
