"An undisclosed number of people who used credit cards at 20 Hyatt, Sheraton, Marriott, Westin, and other hotels in 10 states and the District of Columbia may have had their cards compromised as a result of hack of the hotels’ payment system. HEI Hotels & Resorts, which operates just under 60 hotels and resorts under a variety of brands, said that after being notified by its credit card processor of a potential breach, it conducted an internal investigation that found malware on its payment processing systems at the 20 properties. The malware was designed to capture debit and credit card information such as names, card account numbers, card expiration dates and verification codes, as it flowed through the systems. According to the Norwalk, Conn., company, the hack potentially affected cards used at point of sale terminals, such as those at the hotels’ restaurants and stores, between December 2015 and June 2016. Systems at a few of the affected locations were found to have been infected with the malware as early as March 2015."
