T1087.002 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 groupon 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.

Mitigations

ID Mitigation Description
M1028 Operating System Configuration Prevent administrator accounts from being enumerated when an application is elevating through UAC since it can lead to the disclosure of account names. The Registry key is located at HKLM\ SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\CredUI\EnumerateAdministrators. It can be disabled through GPO: Computer Configuration > [Policies] > Administrative Templates > Windows Components > Credential User Interface: Enumerate administrator accounts on elevation.1
