Jason’s Deli says customer data exposed in credential stuffing attack

Jason’s Deli is warning of a data breach in notifications sent to customers of its online platform stating that their personal data was exposed in credential stuffing attacks.

In a data breach notification sent to customers, Jason’s Deli says hackers obtained credentials of member accounts at Jason’s Deli from other sources and, on December 21, 2023, used them in a credential stuffing attack against the restaurant’s website.

“On December 21, 2023, we learned that an unauthorized party had obtained an unknown number of Deli Dollar and online account login credentials most likely from other data breaches or other sources not involving Jason’s Deli,” reads the notice.

“We do not know the number of accounts that the unauthorized party was able to access, but out of an abundance of caution, we are sending this notice to all potentially affected account holders,” reads the data breach notification from Jason’s Deli.
