Marriott announced a data security incident that impacted up to 500 million guests who made a reservation at a Starwood property during the last four years. According to the company’s notification, the Starwood guest reservation database has been accessed by unauthorized actors since 2014. Compromised information includes customer names, and potentially their corresponding physical and email addresses. Passport number, Starwood Preferred Guest (SPG) account information, date of birth, gender, reservation details, and communication preferences may have also been exposed for approximately 327 million of the total guests affected. Marriott was alerted to the issue on September 8th of this year and began notifying affected customers via email on November 30th. The NJCCIC recommends those who stayed at a Starwood property during the last four years closely monitor their accounts and report fraudulent activity as soon as possible. We also recommend enrolling in any free credit monitoring programs offered by Marriott.
