35:34 push and pop. If the stack grows down (towards lower and lower memory locations as in your animation, which is correct for the x86 architectures), then PUSHing will DECREASE the stack pointer. POPing will INCREASE the pointer.

Honestly it seems like finding materials on rev engineering specifically is a lot harder than most other tech topics. Might just have to cave and read that one 1000 page book to hopefully gain a decent understanding

@@Tyler-jd3ex true which is really odd considering it's a vast and fun field. You pretty much have to research it all by yourself with blood and sweat if you have a specific aim in mind. I guess the fact that it's quite easy to get into illegal territories plays a part in how hard finding good material is which is a shame...

@@ant-mf6kl It’s such a niche area. Out of 100 people you won’t find coders really. Out of 100 people it’s likely none of them know assembly… and then even of people who do know it, only so many of them make videos or help others. It’s so difficult! I often just wish I knew somebody who could show me stuff that can be taught quickly but is so hard to figure out yourself. Well if you ever need help I suppose you can try to ask me! 😂

Quick question and this may be out of the scope pf your class but I was working on my own files and I have a ton of instructions on my machine considered RAW and it says unknown and the instructions give errors with ?? Question marks. Any idea what this means? Thanks again!

Nice video, one comment - the code in the example at 42 minutes is in error. Due to the lack of ret after the mov rax, 0x02 it will run onto the mov rax, 0x01. I e. No matter if the result of the comparison is true or false you will still end up with 0x01 in rax.

Starting from the slide @37:20 to about @40:00 were you using RIP & EIP interchangeably? When you say "mov" - is the value actually _moved_ as in the source register is cleared? Or is the value copied? For example after the instruction mov rax, rbx - what is in rbx? Similar question for popping values off the stack - Does that just increments the stack pointer, and whatever values were in that memory will continue to be in that memory until the stack pointer is decremented again & new values get written?
@nikos4677 Жыл бұрын
mov copies the value. So pop register does 2 things. In x86 It looks like mov register, [esp] and then add esp, 4. So mov copies the value. So it remains the same

The teaching is awesome, but you should consider getting a better microphone (like a large condenser microphone, and not one from a headset... they're never good) and/or not compressing audio that much because it's lacking some frequencies and have lots of hissing, so I have to listen to it pretty loud to be able to understand, which makes it a bit unpleasant to the ears.
can you tell me the entire roadmap for learning RE?
@TalsonHacks2 жыл бұрын
Learn the following: 1- Executable files format (PE & ELF) 2- C/C++ Programming 3- Assembly Programming 4- Debugging tools like GDB and WinDBG 5-Debuggers and decompilers like IDA and Ghidra 6- Do reversing CTFs and challenges, crackmes, etc. Good luck

Fun Zelda series fact - Nintendo took kind of an easy out when deciding how to canonize all of the entries in The Legend of Zelda series. They named Link the Hero of Time, and consider the link in each game to be a reincarnation of said Hero of Time. So the most you can say is that he's Hyrulian, as his race changes throughout the series.

I might be mistaken…but isn’t C more of a ‘low level’ language, and a high level language would be something more like python or even js ?
@rkakkar007 Жыл бұрын
from an application development perspective - yes from a systems-level perspective - probably no
@mallninja9805 Жыл бұрын
For most of its life C has been considered a high-level language because it abstracts away the hardware details. The language is machine-independent, you don't have to directly manipulate registers or manage the stack, etc. In recent years people have taken to thinking of C as "low-level" because you *do* have to do more hands-on memory management than with something like Java, and you *can* still get into the guts of the machine if you so choose. But I think "official" definitions (if there are such things) still classify C as a high level language.

I have a question for you when it comes to wanting to crack a game. Do you personally know if there is anyone talented enough in the scene to reverse engineer the game Path of Exile? People say it's one of the worst targets they've ever attempted, with a bunch of abstraction layers and you get perma banned if you even look too long. It's a live server client and the game is free, but people want to make their own private server out of it to be able to play the content the way they want, in a non-profit fashion obviously. Any ideas on how you would go about bypassing the drm on this live service client and getting the source code for people to make their own private server out of it?
