Mastercard Priceless Specials

Mastercard Priceless Specials operates as a loyalty program managed by Mastercard. The program provides participating customers with special offers and benefits, likely tied to the use of Mastercard payment products. Based on the incident details, the program was active in Germany, indicating a market presence in at least that country. The core function involves managing customer participation and distributing promotional benefits associated with card usage.

The program distinguishes itself through its association with the Mastercard brand but faced a significant cybersecurity incident. In August 2019, a data breach compromised extensive customer personal information managed by the Priceless Specials loyalty program. This breach originated from a third-party vendor responsible for the loyalty platform infrastructure. Exposed data included sensitive details such as payment card numbers, names, dates of birth, gender, mailing addresses, email addresses, and telephone numbers. The compromised information was subsequently published online. In response, Mastercard suspended the German segment of the program and removed hosted data. Affected individuals were notified and offered credit monitoring and identity theft prevention services. Authorities in both Germany, where the program was active, and Belgium, the program's headquarters location, were notified about the breach. Investigations into the incident were ongoing following the discovery. Sensitive authentication elements like account passwords and card security codes were reportedly not compromised in this specific breach.
