Marriott International said on Friday that a guest reservation database of its Starwood Hotel brand was breached, potentially exposing information on about 500 million guests.
The company said its investigation showed that an unauthorized party had copied and encrypted information, and that there had been unauthorized access to the Starwood network since 2014. The company said it had taken steps to rectify the situation.
For about 327 million of these guests, the information includes some combination of name, mailing address, phone number, email address, passport number, Starwood Preferred Guest account information, date of birth, gender among other personal details, Marriott said.
