Zaxby's Franchising, Inc., the Georgia-based restaurant chain which operates over 500 restaurants in 13 US states, has issued a warning to customers after identifying pieces of malware on the computers from around 100 of its establishments.
The suspicious files were discovered after credit card processing companies noticed that the locations represented a common point of purchase for fraudulent activity.
“During the course of its forensic investigation, Zaxby's Franchising, Inc. identified some suspicious files, including malware, on the licensees' computer systems at certain Zaxby's locations,” the company stated.
“Because those files could have been used to export guest names and credit and debit card numbers, Zaxby's Franchising, Inc. informed appropriate law enforcement authorities of the potential criminal activity.”
In order to prevent future intrusions, the company has implemented additional security mechanisms. In the meantime, Zaxby is working with the affected stores to provide notice to customers who might have been affected.
They advise all their guests to monitor their bank accounts for any suspicious activities.
