Up to 500 million Starwood customers hit by data breach
Marriott International has said 500 million customers of its Starwood division have been targeted in a data breach.
he hotel company said the guest reservation database of its Starwood network, including those who have booked W Hotels, Sheraton, Le Méridien and Four Points by Sheraton, had been compromised by an ‘unauthorised party’.
The unauthorised access dates back to 2014.
Marriott-branded hotels are not affected as they use a separate reservation system on a different network.
Marriott said it was alerted by an internal security tool that somebody was attempting to access the database.
After investigating, it was discovered an ‘unauthorised party had copied and encrypted information’.
The database contains records of up to 500 million customers. Of those, the information on 327 million guests included ‘some combination’ of information, such as name, mailing address, phone number, email address, passport number, account information, date of birth, gender, and arrival and departure information
