This is the community for all things hacking and cybersecurity, try keeping it legal. That said I don't take any responsibility for anything that happens/comes from this group but I will try being the best mod that I can to prevent anything from happening.

Why can't I understand hacking. (lemmy.ml)

I really don't know how to explain but hacking is difficult to understand. Like I watched tutorials on Youtube, took courses and read many books but still I feel like I know nothing. Watching Mr Robot and other documentation made feel even worse, you might say Mr Robot doesn't portray the real world but the documentation do. Like this video I was completely baffled at how I didn't have a single clue how they did it what techniques they used.

After all that though, I don't want to give up on hacking, I want to learn more advanced stuff. If you have an recommendations please dm me or comment.

Sorry for my bad english learning to write too.

A basic grounding in computer science would be a good starting place.

Do you know the difference between the various processor architectures and operating systems? Do you know the difference between real time computers and interrupt based systems? Are you familiar with the seven layer network model and which layers the different services interact with the hardware and application software? Are you grounded in cryptography and the system of public and private keys, modulo operations, prime number factorisation?

This is assuming that you already understand coding and are proficient in at least one language. None of these skills and knowledge on their own are indispensable or completely necessary but these things are what computers are made of, how they communicate and how they are secured.

Where can I learn those things?

I'm probably in the same boat as you, I have zero formal CS education. The way I originally learned was various: by embarking on small projects, fixing broken computers so I could play games, reading books, watching videos. The key thing in learning any subject is to recognise that when you don't understand something it's usually because some foundational knowledge is missing. You cannot properly understand a computer file system before you grasp the concept of binary numbers, bits and bytes, for instance.

Lately I've been using Chatgpt. You can ask it to write code in any language. Ask it to solve a particular problem and then start dismantling the answer, step by step. When you don't understand the answer, ask it to elaborate. For your purposes, you could ask it to script a port scanner on your home network. This is key skill for any aspiring hacker and if you can get that working on your LAN, those principles can be adapted to WAN. Get a copy of the CIA vault 7 library, ask chatgpt to explain snippets of the code. I would imagine you have to preface your questions as coming from a 'white hat' perspective or it may balk.
