# T1069.002 - Domain Groups
## [Description from ATT&CK](https://attack.mitre.org/techniques/T1069/002)
<blockquote>Adversaries may attempt to find domain-level groups and permission settings. The knowledge of domain-level permission groups can help adversaries determine which groups exist and which users belong to a particular group. Adversaries may use this information to determine which users have elevated permissions, such as domain administrators.

Commands such as <code>net group /domain</code> of the [Net](https://attack.mitre.org/software/S0039) utility,  <code>dscacheutil -q group</code> on macOS, and <code>ldapsearch</code> on Linux can list domain-level groups.</blockquote>
