What it detects

This rule detects insmod being used to load a kernel object module on Linux, a technique attackers use to install rootkits at the kernel level. Loadable kernel module rootkits hide processes, files, and network activity from userland tooling. Detecting insmod of a .ko module surfaces potential kernel-mode persistence and evasion.
