North Korea hacked into the personal emails of an aide to the South Korean president, his office confirmed. Ednews reports the following referring to the BBC.
The breach occurred in the run-up to President Yoon Suk Yeol's state visit to the UK last November.
The staff member was hacked after using a personal email account for official work, the president's office said.
A local newspaper cited a high-ranking government source as saying hackers had accessed Mr Yoon's trip schedule.
The Kukmin Ilbo newspaper added that messages sent by the president had also been stolen.
But the president's office would not divulge what information was stolen.
This is thought to be the first time the North has successfully hacked a member of the South Korean president's team.
