The Esp8266

1 / 4

we will require two esp8266 for evil-twin, one of the esp will disconnect all the devices from the victim's wifi which we call Deauth Attack And the Another One Will Create A Fake wifi Network With Same SSID When the Victim will try to connect with the wifi And enter the password on the fake Phi**ing page we will get the password of the original wifi. 

Setup Esp8266 -1

I had Already made a tutorial to Setup the Esp8266- 1 for Deauth Attack You Can Watch the Tutorial on Youtube or Checkout The Guide Here , you can try different kind of attacks using this.

Setup Esp8266 -2

To Setup Esp8266- 2 we require

• Usb Cable 
• Arduino IDE installed in our desktop
• A powerbank (optional)
• Driver installed in pc

Step-1

1 / 2

Step-2

1 / 4

This is The Defualt SSID "FREE WIFI" which you can also change later using your phone

Change Headings 

1 / 3

Your Can Customize the Form from here

Code

Select The proper Com port and board as esp8266

Trouble shooting advice - download drivers if com port is not showing

1 / 4

Power Up 

Now Connect Both the esp with A power supply, you can use powerbank or Even your phone using Otg, Make sure You give 5v only otherwise you will end up burning your boards

Testing

Now we need one wifi which will be our target, a mobile which will act as victim and one mobile to perform attack.
Watch the first part and Deauth Target.
Open Wifi and connect with 2nd esp it will be shown with the default ssid you entered while entering the code

1 / 4

After connecting go to browser and type 172.0.0.1/ssid

1 / 2

Enter the SSID of the wifi you want to attack

1 / 3

Now the same SSID will appear And victim will try to connect with the fake wifi because the real one is under deauth attack, no device will be able to connect with the real wifi during deauth attack

Passwords

now the password entered by the victim in the fake panel will be shown to you on the ip address 172.0.0.1/pass and now you can enter password and connect to real wifi after turning off deauth attack
