Wifi Hacking Using ESP8266



How Does Deauthentication works..?



 

Client send the authentication request to the AP(access point (WiFi)). Thats requests contain our password .If its match  the AP password its send Authentication Response(yeah connect me..!). Next the Association Requests is finished its make a bridge to send the data or receive the data . When we send the Deauthentication Requests to the AP (Okay i will cut the connection to you ),the same thing is happen where we perform a Deauthentication attack.whatever device is connected to the network is disconnected ,when we stop the attack ,its automatically connected sometimes its make an error to connect.

Difference between Jammer & Deauthenticator

To jam a network, you need to broadcast radio signals on the same frequency, overpowering the original signal. Its cancel each other

Deauthenticator its not jamming the network its send the Deauthentication frame to the network , its disconnect the device.
