GCHQ’s National Cyber Security Centre with UK industry and 15 international partners shine light on best protections against methods used by China-linked threat actors. Covert networks, often made up of compromised devices such as smart devices, are being used to disguise the origins and attributions of cyber attacks. Organisations urged to follow the protective advice outlined in the new advisory launched on Day Two of CYBERUK 2026 conference to combat this risk. International cyber agencies are calling on organisations to understand and better defend against the cyber threat from covert networks by following new joint advice published today (Thursday). The National Cyber Security Centre (NCSC) – a part of GCHQ – alongside industry and 15 international partners from across nine other countries, have issued a new advisory, highlighting how to defend against these attacker tactics which are believed to be used by the majority of China-linked actors to obscure malicious cyber activity.
