Kernel modules can be used to automatically execute code when a host starts up. Attackers sometimes use kernel modules to gain persistence on a particular host, ensuring that their code is executed even after a system reboot. Kernel modules can also help attackers gain elevated permissions on a system.
Loading a malicious kernel module is a type of rootkit. Rootkits often create backdoor access and hide evidence of themselves. This includes process, file, and network activity.
Kernel modules are loaded from the /lib/modules
directory in Linux. This detection watches for all new files created under that directory.
