I have read that I can dump the binary from the bootloader using the tool avrdude.

I know that I cannot get directly the source code but I was planning to use a disassembler to do the translation. Which has an ATmega32u4 onboard chip and and USB bootloader "AVR109 compatible", according to its description on Adafruit's website.

Whether it is a malicious device, a prank, or an automation tool I want to find what's it purpose and the code. It was recognized as a keyboard by the system, and started clicking and typing. I recently found in my office a suspicious device which I plugged in a spare computer.
