The intrusion dates back to 2014 but was not detected until last September and it was not until last week when its reach was known. Their shares fell 5% before the Wall Street appetite.

The company reports that in most cases, hackers were able to access information from clients who stayed overnight on their properties such as names, addresses, phone numbers, emails, passport numbers and travel itineraries. It is not ruled out that the introsu could also have access to data related to credit cards.

Marriott says he is doing everything he can at this time to resolve the situation and assist clients. The security breach was detected two months ago with an internal tool that indicated the problem.
