Organizers of the Winter Olympics in Pyeongchang, South Korea, confirmed Sunday they were subject to a cyberattack during Friday's opening ceremony. The wifi and television in the Games facilities stopped working for about 12 hours, as did the official website. All were restored to normal by Saturday morning local time. "We are not going to comment on the issue. It is one we are dealing with. We are making sure our systems are secure, and they are secure," said International Olympic Committee (IOC) representative Mark Adams, who indicated he did not know the source of the attack and would not share it if he did. The Guardian reports Russia is rumored to be responsible.
