What it detects

This rule detects insmod loading a kernel module (.ko) from a temporary or user-writable directory, an indicator of a loadable-kernel-module rootkit being installed rather than a package-managed driver. Kernel module abuse is a stealthy Linux persistence and defense-evasion technique referenced in the Red Canary Threat Detection Report. Because legitimate drivers load from system paths, module loads from user paths are a strong indicator of malicious activity.
