Follow-up on KIX DUTY FREE Online Pre-order System Failure


Dear Customers,
With regard to the system failure of our pre-order system identified on Wednesday, December 11, we deeply apologize for the inconvenience it has caused you.     
Further investigation of the problem found that some customers' personal information was viewable on other members' user page during the failure period. We are pleased to inform you that the problem has now been fixed and the system is back to normal. 
The cause of the problem was not due to unauthorized access from external networks and no case of information leakage to any third party has been reported.  
●Date/time of occurrence
5:57 pm on December 10 to 2019 to 10:30 am December 11, Japan time
●Problem description and corrective action taken
During the above period, personal information of the account of some registered members continued for up to 30 minutes after login and was viewable by other members who logged into their account.  
After identifying the problem on December 11, we deactivated the server for the pre-order website to secure the safety at around 10:10 am and then suspended the website at around 10:30 am on the same day so that no one can access and change the registered information. 
The failure was fixed based on our investigation and analysis, and the website operation was resumed at 8:30 pm on December 13.
●Extent of impact 
Personal information of up to 816 customers who logged into their account during the above period
(During the period, personal information of the account of some members was shown, for up to 30 minutes after login, on other members' account. Given the nature of the incident, it is difficult to retrospectively identify exactly how many personal data records were accidentally displayed.)
