It was reported yesterday that the organizers of the Pyeongchang Winter Olympics 2018 were looking into a possible cyberattack that was executed during the opening ceremony on Friday.
The North's Alpine coach, Pyon Yong Do, says attending the Olympics has a "significant meaning" though winning competitions are important, too.
South Korean President Moon Jae-in has been using the Games in his efforts to re-engage with the North and to pave the way for talks over the North's weapons programme.
From her "side-eye" of US Vice President Mike Pence to hints at Korean unification, Kim has stolen the spotlight at the Winter Olympics.

Bach told Reuters in an interview on Monday he would make the visit on the North's invitation as part of an agreement between the International Olympic Committee and both North and South Korea.
South Korea may also need to persuade traditional allies the United States and Japan, which have raised concerns that the North is attempting to use its outreach as a release valve for worldwide pressure.
