For the second time in less than 18 months, Marriott International has experienced a data breach. It affects up to 5.2 million guests, and the company is emailing all of those whose information may have been exposed. The first incident, announced in November 2018, involved Starwood Hotels & Resorts data; Marriott acquired Starwood in 2016. The information in the latest breach was accessed through an application used by hotels operated and franchised under Marriott brands to provide services to guests. The compromised data includes contact details, such as name, mailing address, email address and phone number; loyalty account information, including account number and points balance but not passwords; additional personal details like company, gender, birth day and month; partnerships and affiliations, such as linked airline loyalty programs and numbers; and preferences, including room and language preferences. Not all guests had all of that information stored in the application. Marriott said it had no reason to believe that the information involved included Marriott Bonvoy account passwords or PIN’s, payment card information, passport information, national ID’s or driver's license numbers.
