MYRTLE BEACH, SC (WMBF) - A Georgia-based restaurant firm says suspicious computer files have been found at some of its locations in South Carolina, prompting it to warn customers about the potential for fraud.
Zaxby's Franchising Inc. said in a statement that the suspicious files may have resulted in unauthorized access to credit and debit card information at more than 100 stores, including several in the Grand Strand area.
"[The files] clearly didn't serve any business purpose, and we don't know who installed them," said Zaxby's CFO Blake Bailey. "That's why we want to get this out to the public."
The Athens-based firm says the affected stores are in Alabama, Arkansas, Florida, Georgia, Kentucky, North Carolina, South Carolina, Tennessee, Mississippi and Virginia.
Two of the affected stores are in the Grand Strand area. According to the chain's website, the Zaxby's at 100 Strand Market Dr. in Myrtle Beach, and 1623 Church Street in Conway were affected.
Company officials say the issue involves malware files, which could have been used to export guest names and credit and debit card numbers. The company says it notified law enforcement of the potential criminal activity. Zaxby's says a forensic investigation hasn't determined whether credit or debit card data left the processing systems of any stores.
Zaxby's has also notified the three major U.S. credit reporting agencies about the incident, but did not notify them regarding any individual consumer.
The company says it is working with all of its store locations to implement additional security measures to prevent further intrusions.
"We've mandated our licensees to contract out two national security firms to scan their systems," Bailey said.
