Jefferson National Parks Association discloses POS breach at Gateway Arch stores caused by a malware infection of the payments systems. The malware was installed before November 2013, when the Point-of-Sale (POS) systems were physically located at other sites: the Old Courthouse and U.S. Grant National Historic Site. Other payments at the Arch, including tram and movie ticketing, and riverboat excursions, are not affected. Other personal information such as addresses CVVs and PINs was not captured because that information is not collected.”]
