Back in 2015, Starwood said “the intrusion involved malicious software installed on cash registers at some of its resort restaurants, gift shops and other payment systems that were not part of its guest reservations or membership systems.”

Marriott said that their network appeared to be working fine and unaffected by this four-year data breach.  So far the investigation only identified unauthorized access to the separate Starwood network.

Starwood hotel brands include W Hotels, St. Regis, Sheraton Hotels & Resorts, Westin Hotels & Resorts, Element Hotels, Aloft Hotels, The Luxury Collection, Tribute Portfolio, Le Méridien Hotels & Resorts, Four Points by Sheraton and Design Hotels that participate in the Starwood Preferred Guest (SPG) program.
