PyeongChang 2018 Winter Olympics Opening Ceremony Disrupted by Malware Attack

The Pyeongchang Winter Olympics (In South Korea) was disrupted by a malware attack before and during the opening ceremony. The cyber-attack involved 12 hours of downtime on the official website, the collapse of WiFi in the Olympic stadium, and the failure of televisions and Internet at the main press center.

Various cybersecurity companies reported that it was a wiper malware attack that had spread through the Winter Games official network using stolen credentials. Wiper malware focuses on taking down networks and systems, and wiping the data. Experts have mentioned the hacker potentially being located in North Korea, China or Russia. Based on the Cisco Talos analysis, the attacker had intimate knowledge of the Winter Games’ network system and knew technical details of the infrastructure such as username, domain name, server name, and password. It has also been considered that the Olympics’ infrastructure was already comprised before the attack, making it possible to allow exfiltration of the used credentials.
