Here is a script to dump the AD extended rights:

AD is mission critical for most of the enterprises today. Here is an article to explain how to dump the AD extended rights applied to AD objects, in order toaudit the results to identity persistent threats or persistent hackers gaining control of AD.

Script:

import-module activeDirectory

function DumpExtendedRight([Microsoft.ActiveDirectory.Management.ADObject] $adobject)

{

foreach($access in $adobject.ntsecurityDescriptor.access)

{

#ignore well known and normal permissions

if ($access.AccessControlType -eq [System.Security.AccessControl.AccessControlType]::Deny) { continue }

if ($access.IdentityReference-eq “NT AUTHORITY\SYSTEM”) { continue }

if ($access.IdentityReference-eq “NT AUTHORITY\SELF”) { continue }

if ($access.IsInherited) { continue }

#check extended right

if ($access.ActiveDirectoryRights -band [System.DirectoryServices.ActiveDirectoryRights]::ExtendedRight)

{

$right = “”;

#this is the list of dangerous extended attributs

#see : https://technet.microsoft.com/en-us/library/ff405676.aspx

switch ($access.ObjectType)

{

“00299570-246d-11d0-a768-00aa006e0529” {$right = “User-Force-Change-Password”}

“45ec5156-db7e-47bb-b53f-dbeb2d03c40f” {$right = “Reanimate-Tombstones”}

“bf9679c0-0de6-11d0-a285-00aa003049e2” {$right = “Self-Membership”}

“ba33815a-4f93-4c76-87f3-57574bff8109” {$right = “Manage-SID-History”}

“1131f6ad-9c07-11d1-f79f-00c04fc2dcd2” {$right = “DS-Replication-Get-Changes-All”}

} #end switch

if ($right -ne “”)

{

“$($access.IdentityReference) can act on the permission of $($adobject.name) ($($adobject.DistinguishedName)) with extended right: $right

} #endif

} #endif

} #end foreach

} #end function

##MAIN

$allobjects = Get-ADObject -Filter * -Properties ntSecurityDescriptor -ResultSetSize $null

foreach ($adobject in $allobjects)
