China's 'Fire Ant' campaign used compromised Cisco routers as platform for more attacks
A hacking campaign attributed to Chinese actors, called Fire Ant, used compromised Cisco routers as a launchpad for further network intrusions, according to security researchers. Rather than simply stealing data, the operation undermined the foundational infrastructure that networks rely on to establish trust.
Why this matters: Routers are not endpoints. They are the pipes everything else runs through. When attackers own a router, they do not just see your traffic — they can manipulate it, redirect it, and use your own network as a weapon against others. Cisco routers sit inside governments, hospitals, businesses, and ISPs. This is not someone breaking a window. It is someone getting a copy of the master key and quietly using it for months.
