# Captura Sem Fio com hcxdumptool
Capture tráfego de autenticação WPA/WPA2 para análise offline.
O hcxdumptool captura tráfego sem fio para avaliações de segurança WPA/WPA2.
A captura pode conter material de autenticação. Ela não revela uma senha por si só.
### Criar uma captura
Inicie uma captura na interface em modo monitor:
```bash
sudo hcxdumptool -i wlan0mon -w Capture.pcapng
```
O comando grava os dados dos pacotes em `Capture.pcapng`.
Use um canal dedicado sempre que possível. Isso reduz a coleta de dados não relacionados.
### Validar a evidência
Confirme que o arquivo de saída existe e contém tráfego de autenticação.
Registre a interface, o canal, o BSSID e a duração da captura junto com a evidência.
Proteja a captura como dados sensíveis da avaliação. Exclua-a quando o período de retenção terminar.

## 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/password-auditing/attacking-with-hcxdumptool.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.
