As we all know, computers completely trust connected input devices like mouse and keyboard. Flipper Zero can emulate a USB slave device, allowing it to be recognized by the computer as a regular input device, such as HID keyboard or Ethernet adapter, just as USB Rubber Ducky. You can write your own keyboard payloads to type any key sequence, as well as fuzzing USB stack on a target device.
