Description

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 <code>net user</code> and <code>net localgroup</code> of the Net utility and <code>id</code> and <code>groups</code> on macOS and Linux can list local users and groups. On Linux, local users can also be enumerated through the use of the <code>/etc/passwd</code> file.

On macOS, the <code>dscl . list /Users</code> command can be used to enumerate local accounts. On ESXi servers, the `esxcli system account list` command can list local user accounts.
