T1069.002 - Domain Groups

Description from ATT&CK

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 net group /domain of the Net utility, dscacheutil -q group on macOS, and ldapsearch on Linux can list domain-level groups.
