Source: Marriott International suffers a second data breach | Panda
In November 2018, Marriott International suffered one of the largest data breaches of all times. At the time the breach occurred, the number of records stolen was believed to be 500, a figure that was later lowered to 339 million, still a considerable amount of personal data.
The personal information stolen in this breach was compromised by an unauthorized third party, who had been able to access the data of clients registered in the company’s network since 2014. The information copied by the cybercriminal included “a combination” of name, home address, telephone number, email address, passport number, account information, date of birth, gender, and hotel check-in and check-out data. Some records also included encrypted payment card information.
