Identifying UART and main() in an AVR firmware (ft. Zeta Two) part 1 - rhme2

Part 1 of reverse engineering another AVR firmware. Zeta Two shows us how to get started with reversing the code for the ATmega328P (AVR) chip. This was a challenge from the rhme2 competition. In this video we identify some I/O functions and the main() function.

LiveOverflow: i need new projects for video
Me: Complete the old one first
😂 xd
Btw best channel for ctfs and reversing on YouTube

one of my favorite channels (the way u explain things is soo simple and amazing)

[YoshiAsk]

Are there any updates for part 2? I find this topic very fascinating, I'd love to see more!

[MyMindTank]

This channel is gold! I love your breakdown explanations, so clear, accurate and understandable!

[jordanhanna]

Love the embedded stuff and going deeper into the related RE. Awesome channel!

Will there be a part 2? Thank you for all the rme2 coverage and educational breakdowns either way

[liorlolobobo]

Great video! cant wait for the next one!

[puppe]

Did you ever publish a part 2? I can't seem to find it.

Thx! Can you recommend resources to help loading the ATMEGA bin to IDA and setup everything? I'm good enough at uC but I've never used IDA, I don't know how to start, a tuto would be nice :)

Hi, is there any video with a software defined radio by you?

[We-kvze]

This all sounds like chinese to me, where should I start learning this? Great videoś btw!

[kevinjohansson]

Please do a vid on exploiting with Spectre/Meltdown.

anyone doing Bare metal from hack the box ? :D

Why didn't you use IDA feature to specify segment + offset to make references to the string data? So that you haven't had to put the comments near the addresses manually. And why didn't you try to learn about IDE + compiler used to create the firmware, first. It would allow you to install it on your local machine and learn about how C functions are translated into AVR code, how the arguments are passed, how the values are returned, etc. And moreover you could find all the code within the standard libraries, which a distributed with the IDE, and then just find the same library functions within firmware. So that you don't have to go through 'deduction' phase.
