More than 335,000 people who dined at Arby's between October 2016 and January 2017 may have had their credit or debit card information stolen, according to a statement from to KrebsonSecurity.
Arby's discovered the security breach in mid-January, but didn't go public about the incident until Thursday due to an ongoing FBI investigation. Malware was found on payment portals and cash registers at hundreds of locations across the US.
鈥淎rby鈥檚 Restaurant Group, Inc. was recently provided with information that prompted it to launch an investigation of its payment card systems,鈥� the statement said.
The fast food chain has more than 3,300 sites nationwide, but none of its franchises were impacted by the breach. Only one-third of Arby's locations are corporate-owned.
鈥淎lthough there are over 1,000 corporate Arby鈥檚 restaurants, not all of the corporate restaurants were affected,鈥� said Arby's Senior Vice President of Communications Christopher Fuller. 鈥淏ut this is the most important point: That we have fully contained and eradicated the malware that was on our point-of-sale systems.鈥�
Law enforcement officials are still investigating.
