BETHESDA, Md. (AP) — The information of as many as 500 million guests at Starwood hotels has been compromised and Marriott said that it's discovered that unauthorized access within its Starwood network has been taking place since 2014.

The company said Friday that credit card numbers and expiration dates of some guests may have been taken. For as many as two-thirds of those affected data exposed could include mailing address, phone number, email address, passport number, Starwood Preferred Guest account information, date of birth, gender, arrival and departure information, reservation date and communication preferences. For some guests, the information was limited to name and sometimes other data such as mailing address, email address or other information.
