description: The following analytic utilizes PowerShell Script Block Logging (EventCode=4104)
|
|
to identify the execution of the `Get-DomainGroup` commandlet. `Get-DomainGroup`
|
|
is part of PowerView, a PowerShell tool used to perform enumeration on Windows domains.
|
|
As the name suggests, `Get-DomainGroup` is used to query domain groups. Red Teams
|
|
and adversaries may leverage this function to enumerate domain groups for situational
|
|
awareness and Active Directory Discovery.

|
search: '`powershell` EventCode=4104 (ScriptBlockText = "*Get-DomainGroup*") | stats count

|
min(_time) as firstTime max(_time) as lastTime by Opcode Computer UserID EventCode ScriptBlockText | `security_content_ctime(firstTime)` | `getdomaingroup_with_powershell_script_block_filter`'
|
|
how_to_implement: To successfully implement this analytic, you will need to enable
|
|
PowerShell Script Block Logging on some or all endpoints. Additional setup here
|
|
https://docs.splunk.com/Documentation/UBA/5.0.4.1/GetDataIn/AddPowerShell#Configure_module_logging_for_PowerShell.
|
|
known_false_positives: Administrators or power users may use this PowerView functions
|
|
for troubleshooting.
