Domain Account

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 such as targeting specific accounts which possess particular privileges. 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. PowerShell cmdlets including Get-ADUser and Get-ADGroupMember may enumerate members of Active Directory groups.

Detection logic

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. Monitor 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.
