Have you made recent bookings with your Starwood account? If so, you should be aware that Marriott is currently investigating a hack of its Starwood guest reservation database.
According to the hospitality company, a recent hack has potentially breached the date of approximately 500 million guests.
The Starwood reservation database spans brands including St. Regis, Westin, W Hotels, and Sheraton.
Marriott noted that the hackers had gained unauthorized access to the Starwood reservation system since 2014. However, the issue only came to light a week ago.
In a statement, Marriott said: “The company recently discovered that an unauthorized party had copied and encrypted information, and took steps towards removing it.”
Hacked information includes guests’ names, phone numbers, email addresses, passport numbers, date of birth, as well as arrival and departure details.
Some guests also had their credit card numbers and card expiration dates potentially compromised.
Unfortunately, the hotel chain was unable to determine if the credit card numbers could be decrypted by the hackers.
Affected guests will receive an official email from Marriott, while all guests will receive a free membership to WebWatcher — a personal information monitoring service.
In the meantime, guests should monitor their Starwood loyalty accounts in case of suspicious activities.
