"description": "Adversaries may attempt to get a listing of local system or domain accounts. \n\n===Windows===\n\nExample commands that can acquire this information are <code>net user</code>, <code>net group <groupname></code>, and <code>net localgroup <groupname></code> using the Net utility or through use of dsquery. If adversaries attempt to identify the primary user, currently logged in user, or set of users that commonly uses a system, System Owner/User Discovery may apply.\n\n===Mac===\n\nOn Mac, groups can be enumerated through the <code>groups</code> and <code>id</code> commands. In mac specifically, <code>dscl . list /Groups</code> and <code>dscacheutil -q group</code> can also be used to enumerate groups and users.\n\n===Linux===\n\nOn Linux, local users can be enumerated through the use of the <code>/etc/passwd</code> file which is world readable. In mac, this same file is only used in single-user mode in addition to the <code>/etc/master.passwd</code> file.\n\nAlso, groups can be enumerated through the <code>groups</code> and <code>id</code> commands. In mac specifically, <code>dscl . list /Groups</code> and <code>dscacheutil -q group</code> can also be used to enumerate groups and users.\n\nDetection: System and network discovery techniques normally occur throughout an operation as an adversary learns the environment. Data and events should not be viewed in isolation, but as part of a chain of behavior that could lead to other activities, such as Lateral Movement, based on the information obtained.\n\nMonitor processes and command-line arguments for actions that could be taken to gather system and network information. Remote access tools with built-in features may interact directly with the Windows API to gather information. Information may also be acquired through Windows system management tools such as Windows Management Instrumentation and PowerShell.\n\nPlatforms: Linux, macOS, Windows\n\nData Sources: API monitoring, Process command-line parameters, Process monitoring\n\nPermissions Required: User\n\nContributors: Travis Smith, Tripwire",
