My 3 methods of Learning Reverse Engineering SMN666

Method I :
An eager desire to learn reverse engineering.
Assembly language. It doesn’t really matter what assembly language to learn first. Because most assembly languages are very similar. But I suggest starting with x86, because there are far more resources about it. My top resources for learning x86 assembly are: https://github.com/0xZ0/Z0FCourse_ReverseEngineering and https://beginners.re
Also, a bit of knowledge of executable file formats will be useful for you.
Each operating system uses its own executable: Windows uses PE, Linux and other Unix-like systems use ELF.

Method II :

Don’t spend too much time on Method I.
Start using reverse engineering tools like Ghidra, Radare 2, x64dbg(my favourite) and IDA Home/Pro.
IDA is the oldest of them and it’s still considered the industry standard for static reverse engineering.
Ghidra might be a great tool for beginners: it’s free, it offers lots of features you can’t find in other free tools, and it has a lot of extensibility.
Even write some simple programs in C and then load them in the tool of your choice to see how they work.
Also, study executable file formats.
Then, Learn how debugging works. It’s a process of dynamically examining and modifying the workflow of a program.
Some debuggers for easy learning are GDB on Linux and x64dbg on Windows.

Method III:

It’s time for you to get your hand dirty and check out some close to real-life scenarios.
Also, you can get a taste of different aspects of reverse engineering and pick some areas you want to focus on.
Find some challenges online. My favourite is simple crackme challenges from https://crackinglessons.com/category/challenges/
You can put your reverse engineering skills to good use.
Then, you can learn about common security vulnerabilities in binary software and try to find and exploit them.
You can start your journey into vulnerability exploitation from https://www.vulnhub.com, https://pwnable.kr, and https://www.hackthebox.eu
Try some methods of packing, obfuscation and anti-reverse engineering.
Play some CTFs. Exploitation challenges are probably included in every CTF nowadays.
Flareon CTF is all about reversing malware-like challenges, and RealworldCTF is about exploiting vulnerabilities in real-life software.
Don’t be ashamed if you can’t solve a challenge right away.
Take your time and you can try to solve a challenge even if a CTF has ended.
Also, if you’re stuck, try to google write-ups for your challenge. https://ctftime.org is a great CTF and write-up database.
