Mastercard Priceless Specials Data Breach (2019)

If you are a customer of Mastercard Priceless Specials, here’s what’s now in circulation.

In August 2019, the German Mastercard bonus program "Priceless Specials" suffered a data breach. Personal data on almost 90k program members was subsequently extensively circulated online and included names, email and IP addresses, phone numbers and partial credit card data. Following the incident, the program was subsequently suspended.

What to do now

Steps that match what this notice says was exposed

Every step below is free and you do it yourself, and none of it depends on Mastercard Priceless Specials.

Tell your bank before you do anything else. Account and routing details are the fastest-moving of the fields in this notice. Call the number on the back of your card rather than any number in an email, and ask them to watch the account and reissue the card.

One more, whatever was exposed: a breach notice is a favourite disguise for a phishing email. If a message about this arrives, do not use its links — go to the company’s site yourself, or call the number on your statement.
