# Kerbrute - Ferramenta

Enumeração de usuários Kerberos com Kerbrute e wordlists de nomes de usuário geradas.

> Kerbrute é uma ferramenta de código aberto projetada para realizar enumeração de usuários em um domínio Kerberos. Ela aproveita as respostas do serviço KDC (Key Distribution Center) para identificar usuários válidos.

### **Enumeração de usuários via Kerberos**

O `users.txt` o arquivo contém uma lista de nomes de usuário potenciais gerados pela combinação de diferentes formatos de nome (nome, sobrenome, iniciais etc.). Esses formatos aumentam as chances de identificar usuários válidos em um domínio do Active Directory.

```

**Operação com um dicionário predefinido**

O Kerbrute também pode ser usado com dicionários públicos como os do SecLists:

* **Opções adicionais**:
  * `/usr/share/SecLists/Usernames/xato-net-10-million-usernames.txt`: Usa um dicionário contendo milhões de possíveis nomes de usuário.

<pre class="language-bash"><code class="lang-bash"><strong>kerbrute userenum -d support.htb --dc 10.10.11.174 /usr/share/SecLists/Usernames/xato-net-10-million-usernames.txt
</strong></code></pre>

# 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/pt-br/ports-and-services/kerberos-88/kerbrute-tool.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.
