Marriott Hotels revealed a massive data breach which exposed the personal and financial information of nearly a half billion customers who made reservations at its Starwood properties over the past four years. Marriott says that for approximately 327 million people, the breach exposed their names, phone numbers, email addresses, passport numbers, date of birth and arrival and departure information. For millions others, their credit card numbers and card expiration dates were potentially compromised.
Marriott said it will begin emailing guests affected by the breach and has created an informational website. There’s also a call center that’s been set up. The company said it’s giving guests a free membership to WebWatcher, a personal information monitoring service. It’s also telling guests to monitor their loyalty accounts for suspicious activity, change their account passwords and check credit card statements for unauthorized activity.
At this point the breach is limited to Marriott’s Starwood properties which 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.
