Mastercard disclosed a data breach to the German and Belgian Data Protection Authorities (DPA) involving customer data from the company’s Priceless Specials loyalty program.

The data was made available on the Internet, with customers’ names, payment card numbers, email addresses, home addresses, phone numbers, gender, and dates of birth being included in the leaked info.
