Stayed at a Starwood hotel in the last five years or so? Every one of you and more—as many as 500 million people, says owner Marriott—are implicated in what would be the second-largest hack of all time.
The company said Friday that credit card numbers and expirations dates of some guests may have been taken. For about 327 million people, the information exposed includes some combination of name, 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.
Yahoo holds the record, with 3bn accounts breached. The only other breach in the same league as these would be the 412m accounts dumped from Adult Friend Finder. Marriott and Starwood merged two years ago, but open season at Starwood's servers apparently continued until September this year.
