According to Marriott, the contact information of customers (name, postal address, email address, telephone number, as well as gender and date of birth), information from their accounts in the loyalty program (account number and points, but not password) could leak in the public domain). The company claims that there was no access to credit card data and identity cards.

“At the end of February 2020, the company determined that guest information could be accessed using the credentials of two franchise employees. <...> After it was discovered, the company disconnected these accounts and immediately launched an investigation,” Marriott said.

Marriott International owns more than 7 thousand hotels in 130 countries under 30 brands. Among others, the company includes such networks as Ritz-Carlton and St. Regis. By 2021, Marriott planned to open more than 1.7 thousand new hotels around the world.
