Starwood Hotels, which is part of Marriott International, reports that the illicit entry to their systems was detected on September 10th, but after closer look it was revealed that the system might have been compromised for years.
The database vulnerability was abused first in 2014, and after years of access Marriott estimates that hackers have had access to information from up to 500 million individuals.
At least 327 million customer names, addresses, phone numbers, dates of births, genders, email addresses, Starwood rewards information, arrival and departure dates, reservation dates, communications preferences and even passport information were leaked.
Also encrypted credit card information was among the data leaked.
Marriot noted that it will be contacting all customers that were affected by email starting today.
Marriott bought Starwood Hotels in 2015 making it the world's largest hotel company. Starwood Hotels includes 11 hotel brands, including the likes of W Hotels, St. Regis, Sheraton, Westin, and Element.
