Marriott Hotel Guests Massive Data Breach and Theft

In April 2019, Lieff Cabraser was named to the Plaintiffs’ Steering Committee in the multidistrict privacy and data theft litigation arising from hotel giant Marriott’s 2018 data breach, In re: Marriott International Inc. Customer Data Security Breach Litigation, No. 2879 (JPML).

Background on the Case

On November 30th, 2018, the Marriott Hotel chain reported that data relating to up to 500 million guests had been accessed and copied via its Starwood reservations system. The compromised and stolen data includes names, addresses, credit card numbers, travel histories, and even passport information for some guests. The data attack started as early as 2014, and may well be the largest personal record theft of all-time of such detailed private data.

The data theft was discovered in early September 2018 but only just reported publicly. It affects Marriott properties including Sheraton, Westin, W Hotels, St. Regis, Four Points, Aloft, Le Méridien, Tribute, Design Hotels, Elements and the Luxury Collection.
