NDH 2k15 Blackbadge Challenge

This repository contains files used to solve the challenge which was on the Blackbadge of 2015' edition of the Nuit du Hack:

• dump.ihex contains the firmware and the bootloader which were on the badge.
• extflash.ihex contains the content of the external EEPROM after solving the games on the badge.
• writeup.tex is a write-up in French of the challenge, written in LaTeX.
• writeup.pdf is the compiled write-up.
• atmega32u4.py, avr8bit_instructions.py and decode_firmware.py are Python3 scripts which were used to reverse-engineer the firmware. The output of decode_firmware.py is provided in dump.disassembled.txt.
• decode_extflash.py is a Python3 script which decrypts the content of the external memory (extflash.ihex). Its output is provided in extflash.decoded.txt.
• Makefile allows using make command to build the generated files.
