Moe’s Southwest Grill, McAlister’s Deli, and Schlotzsky’s, the three restaurant brands of multi-channel foodservice firm Focus Brands, have reported a payment card incident.

The companies detected unauthorised activity on its computers that are used for payment processing at some of the corporate and franchised restaurants.

The three restaurant brands have selected a cyber-security firm to start an immediate investigation into the incident.

The investigation is focused on payment card transactions made at impacted locations from April to July 2019.

However, there are no complete findings of the incident to date as the companies are still investigating the incident to identify the specific restaurants and time frames involved.

The brands have also notified law enforcement and the payment card networks regarding the incident.

In separate statements, the three brands said: “It is always advisable for consumers to closely monitor their payment card statements for any unauthorised activity.

“Customers should immediately report any unauthorised charges to the bank that issued the card because payment card rules generally provide that cardholders are not responsible for unauthorised charges reported in a timely manner. The phone number to call is usually on the back of the payment card.”

In addition, the three brands have taken measures to contain the activity, as well as implemented additional security enhancements to avoid any such incidents in the future.

Focus Brands develops multi-channel foodservice brands. Its brands include Auntie Anne’s, Carvel, Cinnabon, Jamba, Moe’s Southwest Grill, McAlister’s Deli, and Schlotzsky’s, and Seattle’s Best Coffee.
