ESP8266: Super compact WiFi Snipper for DeAuth attack

Hello world! Few years ago, a new chip came to the market which started a new revolution! Yes, i am talking about the ESP8266. This chip is way more powerful in terms of CPU architecture, clock frequency, flash size and power consumption if we compare it with existing arduino boards that usually contains Atmel’s AVR controllers. Actually i bought this ESP-01 modules few years back which was originally flashed with good old serial AT command firmware. Over the time, I figured out that the same chip can be directly programmed through the Arduino IDE. This feature is so amazing that you can practically use all existing arduino libraries and the same IDE to program the ESP8266 according to your need by flashing your own arduino sketch. (Word of caution: It will remove your existing AT commands firmware from the chip). After experimenting a lot with typical IoT stuff like thingspeak API or Blynk platform, I stopped working with ESP8266 for few months. During this period, I learned about stuff related to penetration testing of Wi-Fi. If you want to know more about cracking WPA handshakes click here to know more because its certainly out of the scope of this post. I thought, it would be great to build a device which is able to deauth all nearby WiFi devices instead of running deauth attack from terminal by entering bunch of commands. Thus, once again, i decided to pull out my ESP8266 module from the drawer after long time!”
