A cyberattack paralyzed internet networks at the opening ceremony of the Pyeongchang Winter Olympics, in what appears to have been a bid to embarrass the organizers of the games.

Hacking caused both local area network (LAN) and wireless communications to fail during the opening ceremony on Feb. 9 and prevented tickets from being printed from the Olympics website, according to Yu Chae-yeon, a spokeswoman for the Pyeongchang Winter Games. The systems were restored at around 8 a.m. the following day and organizers are investigating who was behind the attack, she said.

The hackers knew usernames, server names and passwords used for the Olympic Games infrastructure, Cisco’s Talos threat intelligence division wrote on its blog, saying it identified 44 individual accounts in the code. Samples of the “Olympic Destroyer” indicate the hackers did not try to steal information. Rather, analysis shows they performed only “destructive” functions. “The samples identified, however, are not from adversaries looking for information from the games but instead they are aimed to disrupt the games,” it said on the blog. “It leaves us confident in thinking that the actors behind this were after embarrassment of the Olympic committee during the opening ceremony.”

The incident underscores the threat of hacking, despite precautions such as South Korea having organized a team of experts well before the event started. Due to the ad hoc nature of cyber operations at the Olympics, the event is more vulnerable to hackers who exploit the lack of security discipline among personnel brought together from different organizations, said Hwang Jun-won, a professor of cyber security at South Korea’s Hoseo Technical College. “Anything that is run temporarily carries risks because not everyone is working hand in glove,” Hwang said. “This hurts the public credibility of the Pyeongchang Olympics given how important networks are in running such a massive event.”

Hwang wouldn’t point to any suspect without analyzing the code first. But he wouldn’t rule out the involvement of actors from North Korea or Russia.

Even though this year’s Winter Olympics was attended by a high-level delegation from North Korea, it has been blamed in past attacks in South Korea and has a history of making provocations while offering an olive branch, he said. Russia was banned over a doping scandal, with some athletes from the country competing as individuals. Calls to the chief technical engineer at Pyeongchang for comment went unanswered.
