This detection rule identifies the execution of the 'groupdel' command on Linux systems, which is used to delete a user group. The detection logic leverages the file path associated with the command's binary. The execution of 'groupdel' is a potential indicator of malicious activity, particularly when performed by unauthorized users, as attackers might employ this command to erase groups they have compromised to cover their tracks and hinder investigation efforts. This rule is essential for enabling security teams to respond promptly to suspicious activities involving group deletion, which can directly impact user permissions and access controls on the affected systems.
