The Pyeongchang Winter Olympics was disrupted over the weekend following a malware attack before and during the opening ceremony. The cyber attack coincided with 12 hours of downtime on the official website for the Winter Games, collapse of Wi-Fi in the Olympic stadium and failure of televisions and internet at the main press center. Cybersecurity experts have already started attributing the Olympic Destroyer malware to hackers linked to either North Korea China or Russia. It’s difficult to accurately attribute this cyber attack to a specific group or nation-state hackers due to sparse technical evidence to support such a conclusion.
