MARRIOTT SECURITY BREACH EXPOSED DATA OF UP TO 500M GUESTS
Hackers stole information on as many as 500 million guests of the Marriott hotel empire over four years, obtaining credit card and passport numbers and other personal data, the company said last week as it acknowledged one of the largest security breaches in history.
The full scope of the failure was not immediately clear. Marriott was trying to determine if the records included duplicates, such as a single person staying multiple times.
The affected hotel brands were operated by Starwood before it was acquired by Marriott in 2016.
