Hyatt Hotels Corp Data Breach (2015)

As part of Hyatt Gold Passport's routine monitoring of member account activity, we found a small number of accounts were accessed by an unauthorized individual utilizing member usernames and passwords. We have no reason to believe, at this time, the login information was obtained through Hyatt Gold Passport, and we continue to analyze and monitor our systems. We have reached out to members we know have been affected to resolve any concerns. To enhance your account security, we are resetting all passwords connected to a username. The next time you sign in to your Hyatt Gold Passport account, you will need to change your password by following the directions below. We strongly recommend that you reset your username and password to a unique combination not used elsewhere. You will not be able to access your account online until you change your password.
