Build A Wifi Jammer

Hey friends, Its Daniel Here, have you ever ever wished to dam all WiFi signals. or simply need to kick somebody out from WiFi or a neighbors WiFi. Well this can be it guys your wait is over. Here is that the $8 DIY WiFi sender to do for yourself.
To see however effective this WiFi sender works I suggest you to see my video here

This sender is thus little you’ll be able to match into pocket. and carry it anyplace. it will high-powered through your power bank or three.7v lipo battery. you’ll be able to choose that WiFi network you would like to jamm and attck thereon . however make sure this can be only for education purpose don’t use for wrong functions.

The 802.11 WiFi protocol contains a thus known as deauthentication frame. it’s wont to disconnect shoppers safely from a wireless network.
Because these packets square measure unencrypted, you simply would like the macintosh address of the WiFi router and of the shopper device that you would like to disconnect from the network. You don’t ought to be within the network or understand the secret, it’s enough to be in its vary.

You will perform multiple attacks on this device like you’ll be able to jam any specific WiFi network otherwise you can do beacon spam or random beacon spam. otherwise you will straightforward death all. Lets begin creating it.

See How The Jammer Works

You can use this Mobile app to control this Wifi Jammer

Step 1: Get Your Parts Ready !

So to make this wifi jammer mainly you will need only one part esp8266.

you can buy this perticular version of esp8266 as this as a nodemcu firmware on it and it is easy to program without any programmer. This esp8266 has a build in programmer.

1) ESP8266
2) Battery (optional)

Here is Full Instruction video

Step 2: Get Your Arduino Compiler Ready

Download the latest Arduino compiler from the Arduino website here

1 Install Arduino and open it.
2 Go to File > Preferences
3 Add

to the Additional Boards Manager URLs.

4 Go to Tools > Board > Boards Manager

5 Type in esp8266
6 Select version 2.0.0 and click on Install (must be version 2.0.0)
7 Go to File > Preferences

8 Open the folder path under More preferences can be edited directly in the file
don’t forget to save!

9 Go to packages > esp8266 > hardware > esp8266 > 2.0.0 > tools > sdk > include
10 Open user_interface.h file with your favourite text editor or just wordpad.

11 Scroll down and before #endif add following lines: if you cant see correct copy it from the txt file included in the project files

typedef void (**freedom_outside_cb__t)(uint8 status);
int wifi_register_send_pkt_freedom_cb(freedom_outside_cb_t cb); void wifi_unregister_send_pkt_freedom__cb(void); int wifi_send_pkt_freedom(uint8 **buf, int len, bool sys_seq);

don’t forget to save!

Step 3: Download the Project

1 Download project files from here (Credit goes to the orginal creator spacehuhn)

2 Open Wifi Jammer > esp8266_deauther > esp8266_deauther.ino in Arduino

3 Select your ESP8266 board at Tools > Board. I used NodeMCU 0.9 but you can try NodeMCU 1.0 or Generic ESP8266 Module

4 Select your programmer at Tools > Programmer > ArduinoISP

5 Select the right port no at Tools > Port If no port shows up you may have to reinstall the drivers.

6 Upload!

Your Wifi Jammer is now ready!

Step 4: How to Use Wifi Jammer

1 First power up your ESP8266
You can use your smartphone if you have a USB OTG cable. or micro usb cable with a power bank or usb wall adapter.

2 Now you can controll your jammer using any smartphone or PC just Connect to ESP8266 Module so
Scan for WiFi networks from your Mobile or PC or MAC and connect to AndroidAP . The password is killwifi . You can change this SSID and Password from the code you uploaded. Once connected, you can use this ANDROID app to control this Wifi Jammer

OR you can open up your browser and go to

3 You can now scan for networks…
Note: While scanning the ESP8266 will shut down its access point, so you may have to go to your settings and reconnect to the WiFi network manually.

…and start different attacks.

4 Click on the attack tab
choose deauth all
boom everyone on the wifi should be disconnected now

you can try other attacks as well

Happy hacking 🙂
