Marriott Starwood Hotel Data Breach: 500 million customer information leaked

Marriott Starwood Hotel Data Breach

Marriott International today announced that a customer reservation database for its Starwood Hotel has been hacked and may have information leaks from about 500 million customers. After the announcement, the share price of Marriott International Hotel fell more than 5% in the pre-market trading today.

The company said in a statement“the company has not finished identifying duplicate information in the database, but believes it contains information on up to approximately 500 million guests who made a reservation at a Starwood property.”

According to Marriott International, the survey revealed that an unauthorized party copied and encrypted the data. Moreover, since 2014, unauthorized access to the Starwood hotel network has begun.

Currently, Marriott International has taken remedial measures but has not released further information. According to Marriott International, this leaked information includes the customer’s name, mailing address, phone number, email address, passport number, Starwood VIP customer information, date of birth, gender and other personal information. For some customers, the information that may be leaked also includes the payment card number and expiration date, but the data is encrypted.

Marriott International Hotel said it has reported the incident to law enforcement and regulatory authorities and actively cooperated with its investigation.
