Around 200 of the 18 million Gold Passport rewards accounts have been hacked, says Hyatt.
In an email sent to rewards program members Tuesday morning, Hyatt announced that an estimated 200 of the 18 million Gold Passport accounts in its database have been hacked.
Hyatt spokeswoman Amy Patti said that during routine account monitoring, the company noticed unauthorized logins across the affected accounts; using the proper names and passwords but without the correct account credentials.
The hack appears to have only affected members logging in with usernames rather than their account numbers. Upon their next login attempt, these members will be prompted to change their passwords and unable to access their accounts until they do so. The company says it also looked to see if any rewards points had been erroneously deducted from the affected accounts and restored all points in these instances.
Hyatt does not believe the hack was a result of security issues within the company itself, as it continues to monitor and analyze its own systems for breaches and vulnerabilities. Gold Passport members Hyatt believes either fell victim to the attack or is at-risk following the attack should have received an email Tuesday morning with instructions on changing passwords.
Any rewards members in the U.S. and Canada who have noticed missing points, login problems or other account issues are encouraged to call 800.228.3360 for assistance.
