Reprint Please specify: @ Small Five righteousness

0x01 Introduction

Do you want to get a WiFi jammer? Collected information on the Internet, found that using esp8266 can achieve simple interference functions, including network disconnection, duplication, deception and so on. Just on hand there is a piece of Tpyboard V202 (30 yuan), also esp8266 chip, also want to change a firmware is also can be completed? Try it on the weekend.

0X02 Building development environment

1, online download a use esp8266 to make Deauth wireless attack of open source firmware, is developed by Arduino.
GitHub Download Address:
It contains the Arduino IDE (arduino-1.8.2-windows.exe) and firmware source code (ESP8266_DEAUTHER-MASTER.RAR). In addition, the esp8266 development package (Arduino15.rar) can be downloaded from the following link: download.

2, after downloading, unzip.

3. Double-click Arduino-1.8.2-windows.exe to install the Arduino IDE. (If you have already installed the Arduino IDE, this step can be omitted).

4. After installation, open Arduino, menu Find File-"preferences, click the Red area to enter the SDK directory." My path is: C:\Users\Administrator\AppData\Local\Arduino15

will be downloaded from the network disk Arduino15.rar decompression, the inside files directly covered C:\Users\Administrator\AppData\Local\Arduino15 file.

Preparation of 0x03 hardware devices

Connect the Tpyboard V202 to your computer and find the Arduino IDE menu tool-"Dev board" on the right-hand side of the menu and find a tpyboard v202 click to select.

0x04 Compile burn Write firmware

1, decompression Esp8266_deauther-master.rar,arduino IDE menu bar file-"Open Esp8266_deauther-master Source Package esp8266_deauther\esp8266_ Deauther.ino

2, Tpyboard v202 use micro USB cable to access the computer. View the ports for the installed USB turns. Turn on your computer's Device Manager (this is COM11).

3, Tools-"Port, select COM11 (according to their own actual port number selection)

4, menu bar below the green Icon menu area, select Upload, start compiling, burn write firmware

5. View the log area at the bottom

Wait for the compilation to complete, the information (status: Changed to "Upload"), press and hold the flash at the same time, click the RST button release, let Tpyboard v202 reset a bit, continue to press Flash, the following information can be released when the Flash button.

When burning the firmware, the small blue LED light on the board has been flashing fast.

After the burn is finished, the display uploads successfully, the small blue led on the board will stop flashing.

0x05 Test Attack effect

1, successfully burning the firmware, open the wireless will search for the name of Tpyboard v202 hotspot, password default tpyboard, to connect.

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

The original page is in English, in order to facilitate the use of my simple translation (WiFi SSID and password has also been modified), the download of the compressed package is also in English original.

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

4, Next we choose a WiFi to do the attack test, in order to facilitate the test is successful, select the usual use of WiFi, my list of select Boda.

5, select the right, click the top menu bar [attack], enter the attack page

6, there are 3 types of attack, Deauther, Beacon and probe-request. At the bottom of the page there are 3 ways to introduce, probe-request really do not know how to translate, the great God can point.

7, we use Deauther mode, block the client connection, click [Start] to start the attack.

8, find a cell phone to do the experiment, see if can also connect to Boda.

If it is the first connection, it will always stop at the interface that is being connected and cannot be successfully connected.
If the original is connected, it will be forced to break.

9. Click [Stop] to stop the attack. After the stop, the phone successfully connected to the Boda.

Finally esp8266_deauther inside also with the WiFi copy and other attack way, everybody oneself is bar.
