Asks DC for all computers, and asks every compute if it has admin access (very noisy). You need RCP and SMB ports opened.

Find-LocalAdminAccess

(This time you need to give the list of computers in the domain) Do the same as before but trying to execute a WMI action in each computer (admin privs are needed to do so). Useful if RCP and SMB ports are closed.

.\Find-WMILocalAdminAccess.ps1 -ComputerFile .\computers.txt

Enumerate machines where a particular user/group identity has local admin rights

Get-DomainGPOUserLocalGroupMapping -Identity <User/Group>

Goes through the list of all computers (from DC) and executes Get-NetLocalGroup to search local admins (you need root privileges on non-dc hosts).

Invoke-EnumerateLocalAdmin

Search unconstrained delegation computers and show users

Find-DomainUserLocation -ComputerUnconstrained -ShowAll

Admin users that allow delegation, logged into servers that allow unconstrained delegation

Find-DomainUserLocation -ComputerUnconstrained -UserAdminCount -UserAllowDelegation

Get members from Domain Admins (default) and a list of computers and check if any of the users is logged in any machine running Get-NetSession/Get-NetLoggedon on each host. If -Checkaccess, then it also check for LocalAdmin access in the hosts.

Invoke-UserHunter [-CheckAccess]

Search "RDPUsers" users

Invoke-UserHunter -GroupName "RDPUsers"

It will only search for active users inside high traffic servers (DC, File Servers and Distributed File servers)

Invoke-UserHunter -Stealth

Without "-Identity" kerberoast all possible users

Invoke-Kerberoast [-Identity websvc] 

use an alterate creadential for any function

$SecPassword = ConvertTo-SecureString 'BurgerBurgerBurger!' -AsPlainText -Force
$Cred = New-Object System.Management.Automation.PSCredential('TESTLAB\dfm.a', $SecPassword)
Get-DomainUser -Credential $Cred

if running in -sta mode, impersonate another credential a la "runas /netonly"

$SecPassword = ConvertTo-SecureString 'Password123!' -AsPlainText -Force
