Russian military spies hacked several hundred computers used
at the 2018 Winter Olympic Games in South Korea, according to anonymous US intelligence officials.

They tried to make it appear as though the intrusion was by North Korea, the officials claim.

Officials in Pyeongchang acknowledged that the Games were hit by a cyberattack during the February 9 opening ceremony but refused to say whether Russia was responsible. That evening there were disruptions to the internet, broadcast systems and the Olympics website. Many attendees were unable to print their tickets, resulting in empty seats.
