In this post you will learn how bootloader works
This is technical writeup for personal CTF challenge I create to show off my understading in hardware/IoT security testcases
CAN (Controller Area Network) is a vehicle bus protocol standard which allows microcontrollers and ECU (electronic control units) to communicate which each other without a host computer. It is a message-based protocol, designed originally for multiplex electrical wiring within automobiles to save on copper.
EEPROM is read-only non-volatile memory whose contents can be erased and reprogrammed using a pulsed voltage often time used in embedded systems (network routers) and smart IoT devices. EEPROM holds firmware data and bootloader, in this post we will explore non-destructive way to read data from EEPROM for security assements purposes.
