Memory reading - Pattern matching

[kantaki]

Hello,

I am working on a opensource memory reading/writing library in scala while using SNA.
But I am very new to the whole stuff like reading certain things from the memory. I mean I know a little bit intel asm and mips asm so I have a rough idea how it will work.

Let's say I want to read the health out of a game. I can't just read it out of the memory because the allocated memory address would obviously change after the application start.

So I can find a pointer which points to the dynamically allocated memory, I guess this is how it works. But even the pointer changes after a recompile, but the logic should stay the same for a longer period of time.

So I thought it might be possible to search for the logic to get the pointer. But it is hard to find something to read.

Could you recommend me some resources?

You can probably apply this general idea to many of the other base addresses. IIRC, there was a program that attempted to do this a while ago. I just can't seem to find it anymore, and I think it used a more advanced method than just AoB Pattern Searching.

okay thanks this was helpful. I just saw that there are tons of open source libs written in other languages. So I think I can learn a lot from them.
