USBKeylogger

Overview

Hardware keylogger. Made based on CH9350 and ESP8266, with Wi-Fi function. Installed between the USB interface and the keyboard USB cable, it can record all input on the keyboard. Keyboard recordings can be downloaded by connecting to a Wi-Fi access point with it turned on. The attachment is the firmware program of the ESP8266 module, which needs to be burned into the module using Arduino. This is only for verification of ideas, please do not use it for illegal purposes!
