Chicago-based hotel operator Hyatt Hotels Corporation informed customers this week that their credit card information may have been stolen by cybercriminals. This is the second data breach discovered by the company within a period of two years.
The incident affects three hotels in the United States (all in Hawaii), three in Puerto Rico, 18 in China, four in Mexico, three in Saudi Arabia, three in South Korea, and one each in Brazil, Colombia, Guam, India, Indonesia, Japan and Malaysia.
According to Hyatt, malware planted by cybercriminals on certain hotel IT systems harvested information from payment cards manually entered or swiped at some hotel front desks between March 18, 2017 and July 2, 2017.
