KBS said it had informed the presidential Blue House after becoming aware of the leak. The office said it was ‌looking ⁠into the matter and intended to take immediate action, according to the report.

The file was posted under the name "passenger list" days before Lee's ⁠trip to Europe earlier this year, it added.

Lee travelled to Belgium and Italy in June, and ⁠also to France for a Group of Seven leaders' summit.

It was unclear how ⁠the confidential file was uploaded or who downloaded it, the report said.
