DSInternals SAM Library

Introduction

The DSInternals.SAM package implements clients for the Security Account Manager Remote Protocol (MS-SAMR) and Local Security Authority Remote Protocol (MS-LSAD/LSARPC). It enables remote manipulation of user accounts and LSA policies on Windows systems.

Key Features

  • Password Hash Injection: Set NT/LM password hashes directly on local and Active Directory accounts
  • Account Management: Query and modify user account properties
  • LSA Policy Access: Read and modify Local Security Authority policies
  • DPAPI Backup Key Retrieval: Extract domain DPAPI backup keys via LSARPC

Usage Examples

Connecting to a SAM Server

using DSInternals.SAM;

string serverName = "dc01.contoso.com";

// Connect to the SAM server
using var samServer = new SamServer(serverName);

// List available domains
string[] domains = samServer.EnumerateDomains();

foreach (string domain in domains)
{
    Console.WriteLine($"Domain: {domain}");
}

Setting a Password Hash

using DSInternals.SAM;

string serverName = "dc01.contoso.com";
string domainName = "CONTOSO";
string userName = "testuser";

// NT hash to set (32 hex characters = 16 bytes)
byte[] ntHash = Convert.FromHexString("A4F49C406510BDCAB6824EE7C30FD852");

using var samServer = new SamServer(serverName);
using var domain = samServer.OpenDomain(domainName);
using var user = domain.OpenUser(userName);

// Set the NT hash directly
user.SetPasswordHash(ntHash);

Console.WriteLine($"Password hash set successfully for {userName}");

Connecting with Alternate Credentials

using DSInternals.SAM;
using System.Net;

string serverName = "dc01.contoso.com";

var credential = new NetworkCredential(
    userName: "admin",
    password: "P@ssw0rd",
    domain: "CONTOSO"
);

using var samServer = new SamServer(serverName, SamServerAccessMask.MaximumAllowed, credential);

// Now perform SAM operations...

Retrieving LSA Backup Key

using DSInternals.SAM;

string serverName = "dc01.contoso.com";

// Get the DPAPI backup key via LSARPC
var backupKey = LsaPolicy.GetDPAPIBackupKey(serverName);

- Added optional named pipe (RPC/NP) transport support.
- Improved MS-SAMR authentication fallback for localhost and missing SPN scenarios.
- Fixed a missing throw in SafeUnicodeSecureStringPointer that silently ignored invalid password byte arrays.
