According to the Reuters, Marriott International said that its Starwood hotels room reservation database was hacked, and about 500 million customer information may be leaked, including the customer’s name, address, phone, passport, etc., and may even include payment cards info such as Number and expiration date for some customers too.
On November 19, 2018, the Marriott International Survey found that guest information in Starwood’s hotel reservation database on or before September 10, 2018 was unauthorised.
Marriott International said it has taken steps to investigate and process data security incidents involving the Starwood Guest Booking Database.
During the investigation, Marriott International learned that since 2014, there has been unauthorized access by third parties to the Starwood network. Marriott International recently discovered that unauthorized third parties have copied and encrypted certain information and attempted to remove it. On November 19, 2018, the Marriott has successfully decrypted the information and determined that the content of the information came from the Starwood Guest Booking Database.
Currently, Marriott International has not completed the identification of duplicate information in the database but believes that the database includes information on up to 500 million guests who booked at Starwood Hotels on or before September 10, 2018. Approximately 327 million of these guests include information on the following: name, phone number, email address, passport number, SPG club account information, date of birth, gender, arrival and departure information, booking date, and communication preferences.
