Account Discovery: Domain Account

Description from ATT&CK

Adversaries may attempt to get a listing of domain accounts. This information can help adversaries determine which domain accounts exist to aid in follow-on behavior.

Commands such as net user /domain and net group /domain of the Net utility, dscacheutil -q group_on macOS, and _ldapsearch on Linux can list domain users and groups.
