What it detects

This rule detects net.exe adding an account to a privileged local group such as Administrators or Remote Desktop Users. Medusa operators manipulate group membership to escalate privileges and retain access, so an account addition to a sensitive group during an intrusion is a persistence and privilege-escalation signal.
