International cybersecurity agencies have issued an urgent Cybersecurity Advisory about a major evolution in state-linked cyber operations tied to the People’s Republic of China. Authorities say threat actors are increasingly relying on vast networks of compromised everyday devices—often called botnets—to obscure their activities, making detection and defence significantly more difficult.
A Strategic Shift in Cyber Warfare
Cybersecurity officials, including the UK’s National Cyber Security Centre (NCSC), alongside partners such as the Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI), say the change marks a turning point in how cyber espionage and attacks are conducted.
Historically, state-backed hackers relied on dedicated infrastructure—servers and domains directly controlled by the attackers. However, investigators now report a widespread pivot toward hijacking consumer and enterprise devices at scale. These include home routers, internet-connected cameras, and storage systems.
The trend is both cost-effective and difficult to attribute, giving attackers plausible deniability while expanding operational reach.
Covert Networks: A Growing and Elusive Threat
These so-called “covert networks” function by routing malicious traffic through thousands—or even hundreds of thousands—of compromised devices worldwide. Each device acts as a node, masking the origin of cyber operations.
Officials say these networks are now used across the entire attack lifecycle—from…
