Credentialed Enumeration - From Windows

Introduction

  • Here we will cover SharpHound/BloodHound, PowerView/SharpView, Group2, Snaffler, and some built-in tools useful for AD enumeration

Active Directory PowerShell Module

Get-Module:

  • This will list all available modules, version, and their potential commands for use
Get-Module

Load AD Module

Import-Module ActiveDirectory

Get Domain Info

Get-ADDomain

Get-ADUser

Get-ADUser -Filter {ServicePrincipalName -ne "$null"} -Properties ServicePrincipalName
  • Notice the ServicePrincipalName at the end of the cmdlet
  • This will show a list of user accounts that are potentially susceptible to to Kerberoasting

Checking For Trust Relationships

Get-ADTrust -Filter *
  • This cmdlet will print out any trust relationships the domain has
  • We can determine if they are trusts within our forest or with domains in other forests
  • We can also determine the type of trust, direction of the trust, and the name of the domain the relationship is with

Why is this important?

  • This will be helpful when taking advantage of child-to-parent trust relationships and attacking across forest trusts

Group Enumeration

Get-ADGroup -Filter * | select name
  • We can then take the results of this cmdlet and feed interesting names back into the cmdlet to get more detailed information about a particular group

Detailed Group Info

Get-ADGroup -Identity "Backup Operators"

  • We can now see additional information about the group

Group Membership

  • With Backup Operators being enumerated, we can now list the members of this group
Get-ADGroupMember -Identity "Backup Operators"

PowerView

PowerView is a tool that is written in PowerShell to help us gain situational awareness in an AD domain.

  • It is essentially the CLI-version of BloodHound

PowerView Functions:

Domain User Information

Import PowerView:

ipmo PowerView.ps1

Get-DomainUser -Identity mmorgan -Domain inlanefreight.local | Select-Object -Property name,samaccountname,description,memberof,whencreated,pwdlastset,lastlogontimestamp,accountexpires,admincount,userprincipalname,serviceprincipalname,useraccountcontrol

Recursive

Get-DomainGroupMember -Identity "Domain Admins" -Recurse

Trust Enumeration

Get-DomainTrustMapping

Testing for Local Admin Access

Test-AdminAccess -ComputerName ACADEMY-EA-MS01

Finding Users with SPN Set

Get-DomainUser -SPN -Properties samaccountname,ServicePrincipalName

SharpView

{% embed url="https://github.com/BC-SECURITY/Empire/blob/master/empire/server/data/module_source/situational_awareness/network/powerview.ps1" %}

General Usage:

.\SharpView.exe Get-DomainUser -Help

Enumerate information about a specific user:

.\SharpView.exe Get-DomainUser -Identity forend

Snaffler

{% embed url="https://github.com/SnaffCon/Snaffler" %}

  • This is similar to Responder, but the Windows version

General Usage:

.\Snaffler.exe -d INLANEFREIGHT.LOCAL -s -v data
