The Winchester Rally’s location was one of three in Kentucky involved in a data breach, according to a press release from the company issued Wednesday.

The other Kentucky locations involved in the breach were the Richmond Road in Lexington and Airport Exchange in Erlanger. The breach also affected Rally’s and Checkers locations in other states.

According to the press release, based on the investigation, Checkers determined malware was installed on certain point-of-sale systems at some Checkers and Rally’s locations, which appears to have enabled an unauthorized party to obtain the payment card data of some guests.

The malware was designed to collect information stored on the magnetic stripe of payment cards, including cardholder name, payment card number, card verification code and expiration date. Based on the investigation, Checkers has no evidence other cardholder personal information was affected by this issue, according to the press release

Not all Checkers and Rally’s restaurants and not all guests who visited the impacted restaurants during the relevant time periods were affected by this issue. A list of the impacted locations and their respective estimated dates of exposure is available at www.checkers.com/security-issue.

“Checkers encourages guests to review their account statements and contact their financial institution or card issuer immediately if they identify an unauthorized charge on their card,” the press release states.
