Marriott Data Breach – Mar. 31, 2020
On March 31st, 2020, the hotel chain Marriott disclosed a security breach that impacted the data of more than 5.2 million hotel guests who used their company’s loyalty application.
Hackers obtained login credentials of two accounts of Marriott employees who had access to customer information regarding the loyalty scheme of the hotel chain. They used the information to siphon off the data approximately a month before the breach was discovered.
The data accessed in the breach involved personal details such as names, birthdates, and telephone numbers, travel information, and loyalty program information.
According to the Marriot, hackers might have obtained credentials of their employees either by credential stuffing or phishing. Previously, the hotel giant announced a data breach in late 2018 in which up to 500 million guests were impacted!
