Dunkin’ Donuts has issued a warning to its ‘DD Perks’ customers, saying a third-party might have gained access to their account information.

“Although Dunkin’ did not experience a data security breach involving its internal systems, we’ve been informed that third-parties obtained usernames and passwords through other companies’ security breaches and used this information to log into some Dunkin’ DD Perks accounts,” said its statement.
Dunkin said the security breach was discovered on October 31. Information that third-parties could have been able to access is what customers would have had in their accounts such as, first and last name, username, 16-digit DD Perks account number and your DD Perks QR code.
