A WiFi connection in today’s modern age is right beneath things like food, water, and air in terms of necessity. Many of our devices are constantly seeking out wireless connections. Besides a password protection, we have very little control over what devices connect to our home networks.
Enter The WiFi Deauther Monster. This unique wireless hacking tool from Travis Lin allows you to perform a WiFi deauth attack or even beacon and probe request flooding. The result? You can select a client you want to be disconnected from the network and poof! They’re gone.
This device was originally designed for spacehuhn’s project ESP8266_deauther, but it is now for sale on Tindie as well. The device works by leveraging a de-authentication frame in the 802.11 Wi-Fi protocol. It’s normally used to safely disconnect clients from a wireless network.
The management packets themselves are unencrypted, so all you need is the mac address of the Wi-Fi router and of the client device you wish to disconnect. There’s no need to be connected to the network yourself, nor do you need to know the password.
Of course, a device like this is meant only for testing purposes on your own network. The device ships ready to use, but it does not include a battery. You could use two 3500 mAh 18650 batteries to power the board for 70 hours, for example.
It can also be a great way to familiarize and protect yourself from these types of attacks in the future. At the very least, it could be fun to rule over your network with an iron fist.
