Authenticated Enumeration

Microsoft Graph Module

Connect to MS Graph

Connect-MgGraph

Use token

$Token = eyJ0
Connect-MgGraph -AccessToken ($Token | ConvertTo-SecureString -AsPlainText -Force)

Get a Token

$passwd = ConvertTo-SecureString "Password123!" -AsPlainText -Force
$creds =  New-Object System.management.automation.pscredential ("[email protected]", $passwd)
Connect-AzAccount -Credential $creds
$Token = (Get-AzAccessToken -ResourceTypeName MSGraph).token
$token

Simple script to automate process

# Prompt for Email
$email = Read-Host "Enter your email address"

# Prompt for Password (input is hidden)
$password = Read-Host "Enter your password" -AsSecureString

# Create a PSCredential object
$creds = New-Object System.Management.Automation.PSCredential ($email, $password)

# Connect to Azure Account
Connect-AzAccount -Credential $creds

# Get the Access Token for MSGraph
$Token = (Get-AzAccessToken -ResourceTypeName MSGraph).Token

# Output the token (optional)
Write-Host "Access Token for Mg-Graph:" $Token

Users

Enumerate all users

Get-MgUser -All

Enumerate specific user

Get-MgUser -UserId [email protected]

Search for users who contain the word "admin" in their Display name:

Get-MgUser -Search '"DisplayName:admin"' -ConsistencyLevel eventual

All users who are synced from on-prem:

Get-MgUser -All | ?{$_.OnPremisesSecurityIdentifier -ne $null}

Objects owned by a specific user:

Get-MgUserOwnedObject -UserId [email protected] | fl *

If a normal user owns a object with a sensitive role such as "Global Administrator', the normal user is indirectly a GA as well!

Groups

Get goups and roles where specified user is a member of

PS C:\Windows\system32> $RoleId = (Get-MgDirectoryRole -Filter "DisplayName eq 'Global Administrator'").Id
(Get-MgDirectoryRoleMember -DirectoryRoleId $RoleId).AdditionalProperties

$RoleId = (Get-MgDirectoryRole -Filter "DisplayName eq 'Global Administrator'").Id
(Get-MgDirectoryRoleMember -DirectoryRoleId $RoleId).AdditionalProperties

User assigned roles:

$userEmail = "[email protected]"
$user = Get-MgUser -Filter "userPrincipalName eq '$userEmail'"

$directoryRoles = Get-MgDirectoryRole

$userRoleNames = @()

foreach ($role in $directoryRoles) {
    $members = Get-MgDirectoryRoleMember -DirectoryRoleId $role.Id
    if ($members.Id -contains $user.Id) {
        $userRoleNames += $role.DisplayName
    }
}

$userRoleNames

Devices
