About

This rule detects the execution of the `grep` command with the `plugins` argument on Linux systems. This command is used to search for YUM/DNF configurations and/or plugins with an enabled state. This behavior may indicate an attacker is attempting to establish persistence in a YUM or DNF plugin.
