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

Commands such as net user and net localgroup of the Net utility and id and groups on macOS and Linux can list local users and groups.^[1],[2],[3] On Linux, local users can also be enumerated through the use of the /etc/passwd file. On macOS, the dscl . list /Users command can be used to enumerate local accounts. On ESXi servers, the esxcli system account list command can list local user accounts.^[4]
