Final Report on the Theft of Customer Information

due to Unauthorized Access to the JAL Customer Information System

Upon the completion of our internal investigation, Japan Airlines has reached the conclusion that the JAL Mileage Bank (JMB) information (*1) of 4,131 customers was compromised due to unauthorized access to the JAL Customer Information System that was first uncovered in September 2014. A verification committee (*2) for this incident, internally established on October 31, 2014 and made up of JAL's external directors and external audit & supervisory board members, has endorsed our internal investigation and our future actions after conducting its verification of our investigation process.

We have found no indication that JMB PINs or credit card numbers linked to JMB accounts were compromised. The JMB Mileage Program continues to remain operational and JMB members may redeem their JMB miles for awards as usual. (*3)

Data security is our top priority at JAL, and we deeply regret that our customers' information was compromised. We are committed to enhancing our information management practices, reviewing the operation of our systems, and otherwise ensuring stronger security measures in the future.

Final investigation report:

Our investigation into this incident was conducted with the assistance of external security consultant firms. In this investigation, we found no evidence indicating that additional customer information may have been compromised, other than the JMB accounts announced in previous reports. Based on our findings, we have concluded that three JAL computers were unlawfully used to transfer the personal information of 4,131 customers to an unauthorized external server.

Customers who have been personally contacted in earlier notification efforts will be informed of this final investigation report by email and by post.
