T1069 - Permission Groups Discovery

Description from ATT&CK

Adversaries may attempt to find local system or domain-level groups and permissions settings.

Windows

Examples of commands that can list groups are net group /domain and net localgroup using the Net utility.

Mac

On Mac, this same thing can be accomplished with the dscacheutil -q group for the domain, or dscl . -list /Groups for local groups.

Linux

On Linux, local groups can be enumerated with the groups command and domain groups via the ldapsearch command.
