From December 11, 2011, around 21:30 to December 14, around 2:30, we received a declaration from three customers that there is service unavailable from three customers, and conducted surveys at both companies As a result, from December 11th to December 13th, 2011, 171 illegal logins occurred by a third party on the PC version of "au one shopping mall", of which 4 customer accounts I confirmed that an unfair purchase procedure was done. As for fraudulent purchase procedures, all cancellation processing has been completed, and financial damage has not occurred.
In addition, for some of the accounts logged in illegally, registration information (customer's name, address, contact phone number, e-mail address, destination information, etc.) may have been browsed. However, the credit card number is masked and encrypted.
Although the details of the cause are being investigated this time, I am aware that it is not caused by external leakage of the customer's password due to unauthorized access to the inside of the system.
