Forces potentially affected DD Perks customers to reset their passwords after learning of unauthorized access to their personal data.
Dunkin' Donuts has alerted DD Perks account holders to a security incident after learning an unauthorized party accessed some of their usernames and passwords, NBC News reports.
DD Perks is a rewards program that lets Dunkin' customers purchase food and beverages for pickup and receive free drinks via rewards points and on their birthdays. On Oct. 31, a security vendor detected a third party accessing users' accounts. It believes these actors stole usernames and passwords from other companies and used them to attempt DD Perks logins.
Information exposed varies from user to user, depending on what was in their accounts. Dunkin' reports third parties may have been able to access first and last names, email addresses (which are used as usernames), the 16-digit DD Perks account numbers, and DD Perks QR codes.
Dunkin' reports its security vendor successfully blocked most of the attempted logins, but it is possible some accounts were accessed. It has launched an internal investigation and forced all potentially affected DD Perks users to reset their passwords and log back in with new ones. It has also taken steps to replace any stored DD Perks cards with new account numbers while retaining the cards' values. Law enforcement is helping identify the parties responsible.
Users are advised to create unique passwords for their DD Perks accounts, as well as all online accounts, and to never use the same password twice.
