Hotel chain Marriott has disclosed that the data in its Starwood reservation program had been insecure from 2014 until recently, which allowed hackers to access the personal information of up to 500 million customers, according to Fast Company. The attackers accessed personally identifying information on roughly 327 million guests, which included some combination of  name, mailing address, phone number, email address, passport number, Starwood Preferred Guest (SPG) account information, date of birth, gender, arrival and departure information, reservation date, and communication preferences. Some of these guests also had both credit card numbers and expiration dates exposed in the process. The remaining guests had "other information" exposed, though the hotel did not elaborate on what exactly that other information is.
