BETHESDA, Md. – Information on so many 500 million people staying at Starwood hotels is under threat, and Marriott says unauthorized access has been detected within the Starwood network since 2014.
The company announced on Friday that some guest credit card numbers and expiration date have passed.
Marriott said its database was violated in September, and the visitor had information about reservations on Starwood properties before or before September 10.
Marriott found that someone had copied and encrypted guest information and said that it is currently working on deleting information.
Marriott has created a website and call center for anyone who thinks it is at risk, and emails will be sent to those who suffered on Friday.
