About this project

WiFi captive portal for the NodeMCU (ESP8266 Module) with DNS spoofing.

The built-in LED will blink 5 times when a password is posted.

Warning! Your saved passwords will not disappear when you restart/power off the ESP8266.

Note: If you want to see the stored passwords go to "172.0.0.1/pass". For changing the SSID, go to "172.0.0.1/ssid"

This is the main page. Here the user will write his password and send it.	This is the post page. The user will be redirected here after posting the password.	This is where the attacker can retrieve all the passwords that has been posted.	Here the attacker can change the SSID name of the Access Point on the go.
