Shoney’s is the latest restaurant chain to face a credit card breach. Best American Hospitality Corp., a group that manages a handful of Shoney’s corporate-owned stores, released a statement detailing an investigation into stolen payment card information at 37 locations spread out throughout South Carolina, Tennessee, Louisiana, Georgia, Alabama, Mississippi, Virginia, Missouri, Florida, and Arkansas.

The company’s investigation found that malware was installed remotely on point of sale equipment that processes payment cards used at some of the restaurants. The malware searched for track data (cardholder name, card number, expiration date, and internal verification code) read from the magnetic stripe of a payment card as it was being routed through the affected computer, the statement explains.

Best American Hospitality Corp. hired Kroll Cyber Security to conduct the investigation. The company found that some of the units were subject to an initial data breach from December 27, 2016 until the malware was contained on March 6, 2017. The date of the first breach varies by location, the statement adds.

“In some instances, the malware appears to have identified data from the card’s magnetic stripe that included the cardholder name and number and in other instances the card data identified by the malware did not appear to include the cardholder name. It is possible that not every cardholder name was identified,” the statement reads.

The 70-year-old Shoney’s has around 150 company-owned and franchised locations in 17 states.

The breach was first reported by Krebs on Security. Hundreds of franchised Wendy’s restaurants were breached last year and Arby’s just released an update on a similar security incident Friday, saying that company-owned stores affected began no earlier than October 20, 2016 and ended no later than January 12, 2017. Read more about that incident here.

Best American Hospitality Corp. also released some steps for guests to protect their information:

It is always advisable to remain vigilant to the possibility of fraud by reviewing your payment card statements for any unauthorized activity. You should immediately report any unauthorized charges to your card issuer because payment card rules generally provide that cardholders are not responsible for unauthorized charges reported in a timely manner. The phone number to call is usually on the back of your payment card.
