2.4/5 GHz Deauther

For many years a common hardware tool for learning about attacking and testing WiFi networks has been the Deauther. The original Deauther was built around the ESP8266 and could create and execute a variety of attacks on 2.4 GHz WiFi networks. The original is an amazing device and has been built into all kinds of form factors including my Flipper Zero ESP8266 Deauther. Of course time and technology has moved onward and now it’s very common to see or own 5 GHz WiFi systems. This new Realtek RTL8720DN-based Deauther tool can now explore and attack both 2.4 GHz and 5 GHz networks simultaneously.

The deauther hosts a WiFi network with the name of RTL8720dn-Deauther and a password of 0123456789. Connect to this network and type the IP of your deauther (typically 192.168.1.1) into a web browser of a choice.

Rescan networks

Rescan and detect all WiFi networks in your area. After a successful scan, the networks are listed in the above table.

Launch Deauth-Attack

Deauthenticates all clients connected to one or multiple networks. Select the networks you want to deauth in the table above and click Start Attack!.

Stopping a Deauth-Attack

To stop an ongoing attack, hit the Stop button.

Leds

The deauther utilizes the RGB led that most devboards have. This is what the different colors indicate:

• Red: The system state. Lights up when the system is usable.
• Green: Lights up when a HTTP communication between a device and the Deauther is happening.
• Blue: Flashes when a deauth frame is being sent.
