(Reuters) - Several U.S. cyber security firms said on Monday that they had uncovered a computer virus dubbed "Olympic Destroyer" that was likely used in an attack on Friday's opening ceremony of the Pyeongchang Winter Games.

Games organisers confirmed the attack on Sunday, saying that it affected internet and television services but did not compromise critical operations. Organisers did not say who was behind the attack or provide detailed discussion of the malware, though a spokesman said that all issues had been resolved as of Saturday.
