Kicks out everyone in your LAN with an ENC28J60 ethernet controller and Arduino.
Using an Arduino with an ethernet controller, this device will perform an ARP spoofing attack to disconnect every client device in your LAN.
It will send an ARP reply every 2 seconds to everyone in the LAN that the gateway is at a random MAC adress. If the network or client doesn't provide any kind of protection against ARP spoofing, it will save the spoofed MAC adress and will be unable to communicate with the gateway.
The ENC28J60 is a cheap 10mbit SPI ethernet controller for Arduino. Because it has a very open and easy hackable library it's perfect for this project and you could even programm a man-in-the-middle attack or other funny stuff with it.
Use a router, network switch or software that provides you protection against ARP spoofing.
Note: I haven't tested it on such protected hardware yet.
Use it only for testing purposes on your own network!
You will need an Arduino and (of course) an ENC28J60.
If you buy an Arduino ethernet shield be sure it doesn't use a wiznet controller (e.g. w5100 or w5500), this project will only work with an ENC28J60!
1. Wire everything up
To do this you need to connect both the Arduino and the controller via their SPI pins. If you're unsure how to do this, you can google for the pinout of your Arduino and the ethernet controller. There are different versions of the ENC28J60 out there. I'm using a shield for the Arduino nano.
2. Install library
You will need to add the ethercard library in Arduino.
How to do this you'll find here: https://github.com/jcw/ethercard
3. Upload the code
Upload the ARP-spoofer code to the Arduino and your done :)
Power it over USB and plug in an ethernet cable, that's all!
Using the WebInterface:
If you set web_en = true in the code, the Arduino won't start the attack by itself.
You have to open its website and start the attack manually.
The IP will be printed out in the serial monitor and the default password is ARP.
Thanks to VoidTyphoon for implementing this feature.
