Dairy Queen has announced that it was affected by a possible malware intrusion that may have affected payment cards of customers at various locations in the U.S.

Of those locations, five were in Alabama, but the Hartselle location was not affected.

The stores that were affected in Alabama included the Decatur, Madison Gardendale, Orange Beach and Gulf Shores locations.

“Upon learning of the issue, we launched an extensive investigation and retained external forensic experts to help determine the facts.,” the company said in a statement. “Because nearly all DQ and Orange Julius locations are independently owned and operated, we worked closely with affected franchise owners, as well as law enforcement authorities and the payment card brands, to assess the nature and scope of the issue.  As a result of our investigation, we discovered evidence that the systems of some DQ locations and one Orange Julius location were infected with the widely-reported Backoff malware that is targeting retailers across the country.  The investigation revealed that a third-party vendor’s compromised account credentials were used to access systems at those locations.”
