The opening of the 2018 Olympics was hit with a cyber attack. The attack lasted 12 hours before the Olympic Officials could take control of the situation. The attack took down the official website, broke wifi and TV for people. Attends couldn't get their tickets to the Olympics due to network being down. The malware was named the Olympic destroyer, which instead of stealing data, it would wipe data has it went through. The attack was suspected to come from either Russia, North Korea or China. According the officials the Hacker apparently had a lot of knowledge of the internal network system and had access to server usernames and passwords. The reason why was the malware was hard coded with credentials to network. Thus making easier for the malware to spread and wipe more data easier.
