This article shows you how to make a cheap WIFI jammer by TPYBoard. The content is concise and easy to understand, and it will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Introduction to 0X01

Do you want to get a WIFI jammer? After collecting some data on the Internet, it is found that simple interference functions can be achieved with esp8266, including network disconnection, replication, deception and so on. Happen to have a piece of TPYBoardv202 (30 yuan) on hand, for more information, please refer to: http://www.tpyboard.com, which is also an esp8266 chip, can also be completed if you want to change the firmware? Give it a try at the weekend.

0X02 builds development environment

1. An open source firmware for making Deauth wireless attacks using esp8266 is downloaded from the Internet, which is developed by arduino.

Github download address: https://github.com/PakchoiFood/ESP8266_deauther

It contains arduinoIDE (arduino-1.8.2-windows.exe) and firmware source code (esp8266_deauther-master.rar). In addition, you need an esp8266 development kit (Arduino15.rar), which can be downloaded from the following link: http://pan.baidu.com/s/1bpnJMkn.

2. After the download is completed, decompress as follows:

Double-click arduino-1.8.2-windows.exe to install arduinoIDE. (if you have already installed arduinoIDE, this step can be omitted)

4. After installation, open arduino, find the file on the menu-"preferences, and click on the red area to enter the SDK directory."

My path is: C:\ Users\ Administrator\ AppData\ Local\ Arduino15

Extract the Arduino15.rar downloaded from the network disk and overwrite all the files in it directly under C:\ Users\ Administrator\ AppData\ Local\ Arduino15.

Preparation of 0X03 hardware Devices

Connect tpyboardV202 to your computer and find the tools in the arduinoIDE menu-"the development board looks down in the menu on the right, and you will find a TPYBoardv202 click to select."

0X04 compiling and burning firmware

1. Extract the esp8266_deauther-master.rar,arduinoIDE menu bar file-"Open esp8266_deauther-master source package esp8266_deauther\ esp8266_deauther.ino"

2. TPYBoardv202 uses microUSB data cable to connect to the computer. Check the port of the installed usb transfer string. Open the computer's device Manager (this is COM11)

3. Tools-"Port, select COM11 (according to your actual port number)

4. In the green icon menu area below the menu bar, select upload, start compilation, and burn the firmware.

5. View the lowest log area

Wait for the compilation to complete, when the message above appears (status: upload), hold down FLASH while pressing the RST button to release, let TPYBoardv202 reset, continue to press FLASH, when the following message appears, you can release the FLASH button.

When burning and writing firmware, the small blue LED light on the board will always flash quickly.

After burning and writing, it shows that the upload is successful, and the small blue LED on the board will stop flashing.

0X05 tests the attack effect

1. After successfully burning and writing the firmware, turning on the wireless will search for a hot spot named TPYBoardv202. The password defaults to tpyboard to connect.

2. after the connection is successful, open the browser and enter 192.168.4.1. Click [I have read and understand the above notice] (this experiment is for testing only, please use it carefully).

The original version of the web page is in English. In order to make it easy to use, I simply translated it (wifiSSID and password have also been changed). There is also an original English version in the downloaded package.

3. After clicking in, scan the nearby wifi first. Click [scan].

4. Next, we choose a wifi to test the attack. In order to facilitate the success of the test, we choose the wifi that we often use, and select boda from my list.

5. After selecting, click * * attack * * on the top menu bar to enter the attack page.

6. There are three kinds of attack methods, Deauther, Beacon and Probe-Request. There is an introduction to these three ways at the bottom of the page. Probe-Request really doesn't know how to translate it. The gods can give us some advice.

7. This time, we use Deauther to block client connections, and click "START" to start the attack.

8. Find a mobile phone to do an experiment to see if you can still connect to the boda.

If it is the first time to connect, it will always stop on the interface that is being connected, and the connection will not be successful.

If it had been connected, it would have been forced to disconnect.

9. Click "STOP" to stop the attack. After stopping, the phone was successfully connected to boda.

10. Esp8266_deauther also contains other attack methods such as wifi replication, right?
