# wifi-spammer
|
||||
|
||||
Anuncia redes inexistentes con los mensajes que quieras.
|
||||
|
||||
Inspirado en [esp8266_beaconSpam](https://github.com/spacehuhn/esp8266_beaconSpam). Originalmente escrito en C, porteado y limpiado a Zig.
|
||||
|
||||
## Bugs
|
||||
|
||||
- Por alguna razón no siempre aparecen todas las redes, y gradualmente van apareciendo menos
|
||||
- No pude cross-compilar a un router MIPS. Estuve varias horas. Queda, en build.zig, build-pcap.sh y upload.sh, mis intentos.
|
||||
|
||||
## Empezar
|
||||
|
||||
Poner tarjeta en monitor mode (no entiendo bien si es necesario porque no estamos monitoreando, pero por las dudas)
|
||||
|
||||
```sh
|
||||
doas ip link set wlan0 down && \
|
||||
doas iw wlan0 set monitor control && \
|
||||
doas ip link set wlan0 up
|
||||
```
|
||||
|
||||
Compilar y ejecutar como root. Actualmente asume que tu placa de red es `wlan0`.
|
||||
|
||||
```sh
|
||||
zig build && doas ./zig-out/bin/wifi-spammer
|
||||
```
