For some time now, I became interested in network security and came across an article on how to make a Wi-Fi Jammer (deauthentication attack). I did not even suspect that you can make someone's life so easy and simple. To make a Jammer All we need is esp8266. The principle of operation is very simple. Our device pretends to be a router and sends information (deauthentication packets) to network users to disconnect. This option does not always work, but it is enough to set an attack on a specific device and you're done. I haven't been able to find information on how to defend myself against such an attack, but maybe one of the forum members knows and will share their knowledge. Remember that you can only use this for educational purposes and testing your OWN network. Link to the video with step-by-step instruction youtube.com/watch?v=9UgFafZhONI
