learning more

Name: Anonymous 2011-10-17 3:24

Well, I'm learning C, but I have a few questions on where to go from there.

After I learn C I plan on becoming ASM literate at the very least.

But how do I learn more advanced things about linux and the way things all work together?

I want to get into computer security as an end-goal, but I would like to be on the research and development side of things, like code-auditing and malware reversing.

So what are some good resources for learning the internals of systems and debugging and shit?

General self teaching thread.

Linux isn't a very good OS.

me too.
Right now I reverse engineer games to cheat and for fun. But I want to get into security type stuff with it. Idk where to look. But i do find game cheating good practice.

I'm not even knowledgeable enough to do that....

Throw me a bone!
Where/how did you learn to do that shit?

its really hard to find good assembly tutorials.
Here's how I did it:
-find a bunch of resources on cracking programs
-read through, do some "crackme"s and get an understanding of
How programs work and how you can manipulate them.
The same methods that are used crack a program can be used to cheat in a game.
 
Example:
Crack Photoshop - reverse it to bypass the registration process so you can get it for free.
Well do the same thing but for games.
Example:
Hack Battlefeild 3 - reverse it for infinite health so you can't die.

It's the exact same thing. Just cracking is illegal.

also
Try writing some simple programs and analze them in assembly.
Start with a hello world program(in a language of your choice), and see what stuff looks like and do more complex stuff as you go.

My favorite assembly tools are Ollydgb(free) and IDA Pro(not free).

Also
Try finding stuff on how to write programs directly in ASM rather than just editing premade programs.

Protip: Goolgle is your friend.

op here, thanks for the links man!
I actually had been looking at crackmes a few days back.
I had a feeling that was where to start.

Thank you very much.

For those not in the know:

What language was RollerCoaster Tycoon programmed in?
It's 99% written in x86 assembler/machine code (yes, really!), with a small amount of C code used to interface to MS Windows and DirectX.
ARE YOU A BAD ENOUGH DUDE TO WRITE A GAME IN ASSEMBLY?

machine code
What's the point? Any decent assembler should generate the best opcodes.

So Mario and Metroid used C++?

Yep! And they drew on screen through std:cout, while std:vector was used to hold tileset.

If you break out of Pirates! on the C64 you can see it's mostly BASIC with some machine language helper routines. Languages like Forth were pretty popular back then.

Not a single time TTD crashed for me, while I managed to crash Sim City 2000 and other games of it's time.

They probably used BASIC as a startup script.

Lolz go look for yourself. There's thousands of lines in there, it's all the main game logic (which is probably why it runs so slow).

But that is C64 and NES had too little memory for BASIC.

I think nintendo used C for N64 games, before that all assembly I guess

How much memory do you think is needed and what do you base that on? Regardless, the original claim was that all C64 and NES game were written in assembly, which is simply uninformed.

Someone with the free time could do a comprehensive survey of the games for those platforms and look for signs of generated code. I bet you'd find surprisingly many, at least outside the action games.

Yeah! Games like Action 52 surely use a lot of "generated code".

Just download one of these big ROM archives and use auto-analyzer on it. C++ generates a lot of garbage.

using Ollydgb [o]
disassemble a C "hello world" [o]
thousands  of ASM code, no clue where to even start [o]

Did i do something wrong or is there a easier way to this? I mean can't you tell the compiler to print the assembled code form your C code?

You used too many [o] tags, and didn't close any of them.
