The Olympic Destroyer malware that has caused damage to PyeongChang 2018 Winter Olympics networks is much more complex than previously thought. Cisco Talos researchers published an initial analysis of this threat yesterday, revealing that Olympic Destroyer was capable of mangling a computer’s data recovery procedures and deleting crucial Windows services, rendering Windows computers unable to boot. The malware has a data-wiping mechanism that attempts to delete files shared on network drives, hence hindering some operations during the games’ opening ceremony. A self-patching mechanism that allows it to mutate and evolve from each infected host to another.
