C and especially C++ developers are actually using compiler explorer for _forward_ engineering. I.e. during development they try optimizations there and see what the compiler makes of it, before putting the best version in their code. It's an amazing tool Matt Godbolt brought into the world.
If one is interested in Reverse engineering themselves, I would highly recommend the book "Practical Malware Analysis: The Hands-On Guide to Dissecting Malicious Software". It can be found online using a bit of googling. I just finished a course with the name Reverse Engineering and Malware Analysis and there we used this book. This course was obviously heavily focused on how windows malware works and can be detected through different means, but reverse engineering was a big part of it.
A more abstract book would be Practical Reverse Engineering by Alexander Gazet and Bruce Dang. Especially if you don't want to go into malware analysis specifically.
I started learning assembly code and disassemblers a couple months ago, with the help of the book "Hacking The Art of Exploitation", really good book but the assembly part was really hard of me. I tried to follow on my computer but had many many issues, got frustrated and just let it go. A couple weeks ago I took it upon myself to read it again, and now I got it a little bit better. For some reason assembly is still challenging for me, but no matter how frustrated you get, take some time, breath, stop for a couple hours maybe days and then try to resume. Would have loved to have this video before. Amazing, thank you so much.
Maybe it's worth mentioning that the intermingled output of source code and assembly can also be achieved (and in fact this is for sure what happens in the background on that website) with objdump -S , if the binary was compiled with debugging enabled. So, even if you are somewhere without internet or don't want to share the code you are working on with whoever is running that website, you can still conveniently self-learn reverse engineering in 2022.
The one thing to remember while learning reverse engineering is that there are a lot of things that you won't get when you try the first time and it's fine. You also have to have a lot of patience since the process of learning reverse engineering can be extremely frustrating and it can make you give up on 5 out of your 10 projects. Always remember that theory will beat practice. Have a goal in mind why you want to learn reverse engineering as that will give you a clear idea of the platform on which you will be working. For example, I want to be a Vulnerbility Researcher and find 0 days on Windows so I would learn all the basics of reverse engineering simple programs on Windows, how to debug them, the tools necessary and I would read through ctf writeups and try stuff on my own. After clearing this up, I would try to increase my level and try malware analysis as it would give me clear understanding of software protections, debugging and understanding a program when almost nothing about the program is known. Then I can proceed to learn about different kinds of vulnerabilities and how they are found and so on.
This is me right now. I’m into malware dev. and most times i need to reverse Engineer the binary I’m writing to see how it’s been executed in memory but just can’t seem to wrap my head around the assembly codes
@@flirtyemy042 the best way to learn assembly is to write own programs and see what assembly code is generated in disassemblers or you might just try making a small project in assembly. You can sort of cheat by just learning about the most commonly used assembly instructions.

What are some good ways for a total beginner to get started? Ive seen some beginner videos but they all seem to intermediate levels and theres only a handful of them out there it seems
+rep godbolt love, didnt know asm like 2 weeks ago, watched a few vids to briefly get a hang of what it does (alot easier than what i wouldve thought actually), then used godbolt to more understand what my code does at a lower level, its really nice being able to look at asm and be able to tell what it does, especially when u can hover over parts of asm and it highlights the code responsible for it! its been a real help. documentation helps alot to for checking out odd looking functions that ive never really seen before :D 10/10
We practiced reverse engineering by rewriting the simple basic utils like cat and tee from their asm dumps. That and also writing some assembly code is helpful
Literally could not have come at a better time. I've been itching to dive into contributing to Metaforce (reverse engineering of Metroid Prime) and have been scratching my head not knowing how to get started
holy macaroni, i didn't know of dogbolt; that's awesome!! and also, i've been reading some arm, but for some reason it didn't click in my head prior that 'b' was branch, facepalm. thank you!
Good content. Reverse engineering is how I got started; after taking classes on a language or doing YT tuorials of a certain framework, I'd clone a large GitHub repo to my desktop and toy around with it. See what I could add, see what made it break, read the errors after each save. That method was just as valuable, if not more so, than the classes themselves.
To be honest i am learning reverse engineering currently (self) and worried that i cannot become one. But this single video give me a boost . Lets see what will happen in future
The motivation will be on and off. Give yourself time. Fundamentals like C, asm, os architecture are important... RE skills is a self learning subject.. you need to keep on practice, research and repeat.
Compiler explorer is actually a really good tool. like if you get cursor to stuff you dont know what it means it will show description of what it is like cmp, rbp and so on. thanks btw didnt knew about this tol.
I might be nitpicking, but at 2:04 you said a (local) variable, isn't it technically a const(ant) here? It's not a variable type where it can be changed by the program unless it's self modifying code ofcourse. Just learning the basics of C and was wondering if I got it right, so it threw me a bit off :D
I'm not exactly sure what you're getting at, but what makes you think this is a constant, as we don't really see the rest of the code? One way of thinking about constants in the context of C code might be a "const" variable, where the compiler /might/ optimize it so that the variable is essentially inlined (as in, for example a function call with the const value gets compiled without the variable on the stack, but rather compiled in as a constant to the function call). I'm not entierly sure how the C compiler handles it, but depending on the optimizations used non-const variables can also be optimized out (possibly not much differently than const variables). The volatile keyword in the example essentially prevents the compiler to apply such optimizations and (in this case) ensures the variable gets placed on the stack.
I don't see anywhere they're declared as 'const', only 'volatile' which actually tells the compiler that the value of this variable may change at any time, esp. without any action from any visible code, and as such it shouldn't attempt to apply optimizations.
@@snoopiiii I think you're misinterpreting the assembly code. The line you're seeing is simply initializing the local variable with a constant value. You can also clearly see in the original C code that there isn't any constant, only variables with the "volatile" modifier applied in order to suppress compiler optimizations.

Hey! I know you're generally focusing on Reverse Engineering programming code, but I was wondering if you have any experience and or helpful tools on learning how to reverse engineer a file format? I've been working on somehting in my past-time but my best approach was just trying to write parsers for the files in question in Haskell (using Megaparsec), which doesn't lead to a quick analysis cycle having to rebuild the program, running it and either handling a huge print output or navigating bit by bit into the data structures to figure out what came out.
I dont understand the functions calls on x86. In your printf it gets assembled to call printf but in mine it gets assembled to call puts. I use the same gcc version to compile so how can that happen?
Hi, thanks for the video. I‘m getting into reverse engineering and find it really fastinating. Could you tell me are there any job oportunity in this area other then pentesting/security.
I don't....feel like this helped. I mean maybe i'm getting something wrong here but i thought the goal was to be able to read and identify code and i learned how to read the assembly but i wouldn't understand what it could represent in the high-level code without the source-code anyways. Especially when the programm is more complex with many more functions calling each other... I don't know where to go from here. How do i interpret the stuff i see?
