Marriott says personal details of 500 million guests at risk after Starwood reservation database hacked
- Investigation shows that an unauthorised party copied and encrypted information
- Hotel chain discovered breach in September and will tell customers on Friday if they have been effected
Marriott International said on Friday that 500 million customers that had made bookings since 2014 may have had their personal data stolen, in one of the biggest hacks ever.
The hotel chain said the hack had affected the hotel reservation systems of its Starwood brand, which was sold to its larger rival in 2016.
Hongkongers who previously stayed at Sheraton, St Regis and W Hotel locations, and other chains that came under the Starwood umbrella, would start to learn on Friday if their data, and what kind of data, had been compromised, the global hotel group said in a statement.
For about 327 million of these guests, a combination of names, email and residential address, phone number, passport number, date-of-birth, hotel reservation information, and Starwood Preferred Guest loyalty card numbers were stolen.
For others, credit card details may have been compromised.
