On Friday, 30 November 2018 the Marriott Hotel announced that it had suffered a data breach, we are all getting a little numb to large breaches but this one is one of the biggest in recent times.

The Marriott revealed that over a four year period, up to approximately 500 million guests who made a reservation using the Starwood reservation system for a hotel within the Marriott umbrella on or before 10 September 2014 may have had their data compromised. For approximately 327 million guests, information that may have been comprised includes a combination of name, address, phone number, email address, password, Starwood Preferred Guest account information, date of birth, gender, payment card numbers, arrival and departure information, reservation date and communication preferences.

Most hotel booking/POS systems have been attacked in recent years and these attacks have proven difficult to detect and trace through to understand the impact, it takes time and significant resources.  If you have used the Starwood reservation system – it is a good time to change the password and update passwords anywhere else you use those same or similar credentials.
