# Enumeración de usuarios con Kerberos

### Objetivo

Kerberos se puede usar para comprobar si los usuarios existen en el dominio.

Esta técnica es útil porque el KDC puede responder de forma diferente según si el usuario existe o no.

{% embed url="<https://github.com/ropnop/kerbrute>" %}

### Creación de una lista de usuarios

Creamos un archivo:

{% code overflow="wrap" %}

```bash
user1
user2
test1
Administrator
Administrador
usuario
carlos
```

{% endcode %}

### Enumeración con Kerbrute

Usamos `kerbrute` para comprobar usuarios válidos:

{% code overflow="wrap" %}

```bash
kerbrute userenum -d whoami.local --dc dc01.whoami.local usernames.txt
```

{% endcode %}

Resultado en el laboratorio:

```
user1
user2
Administrador
```

Esto significa que estas cuentas existen en el dominio.

# 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://hacking-notes.jord4n.pro/es/active-directory/kerberos/kerberos-user-enumeration.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
