BETHESDA, Md. – The information of up to 500 million people staying in Starwood hotels has been compromised and Marriott says that unauthorized access has been discovered that has taken place within its Starwood network since 2014.
The company said on Friday that credit card numbers and expiration dates for some guests may have been taken.
Marriott said that there was a violation of its database in September, which had guest information related to reservations to Starwood properties on September 10 or earlier.
Marriott discovered through research that someone copied and encrypted guest information, and says that he is now working to delete the information.
Marriott has created a website and a call center for anyone who thinks it is at risk, and on Friday it will begin sending emails to those affected.
