Systems hosting content pertaining to the National Games of China were successfully breached last year by an unnamed Chinese-language-speaking hacking group.
Cybersecurity firm Avast, which dissected the intrusion, said that the attackers gained access to a web server 12 days prior to the start of the event on September 3 to drop multiple reverse web shells for remote access and achieve permanent foothold in the network.
The National Games of China, a multi-sport event held every four years, took place in the Shaanxi Province between September 15 and 27, 2021.
