 Posted: Sun Jul 17, 2016 3:21 pm Post subject: Seperate Memory for each Routine Call? [ASM] /MemoryShare |
 |
|
Hey
I have a code that has this for example:
| Code: |
alloc(data,512)
mov [data],eax
nop
nop
cmp [data],0 |
however, another call to the same function is occurring which is changing the content of [data] before the is having its time to execute.
Is there a way to separate the memory locations? I don't want them to share [data].
Thanks

| You can set up a filter or use a different injection point.

I have lots of comparisons, and I can't use a different injection point as the value I need is only there for a short point.
I tried doing a queue, but I can't use the registers cuz they're all busy.

| You're not making sense.

This game runs multiple code at the same time, so if I alter r13 for example, it might be getting used somewhere else. It doesn't make sense, but if I change r13 even for one op, the game will crash. Maybe it's just tamper protection.
Anyways,
Assume this:
| Code: |
mov al,cl
nop
mov al,0
|
If I want to copy the value of al before it changes into 0, then the only injection point is nop. You get what I mean?

Or, you know, at any point above that instruction and get cl instead (or whatever is written to cl, etc.).

Above the instruction are references to KERNEL, I don't want to inject there.
However, I noticed a shortly afterwards, which took me to a location with everything I need ready there and there's no multi call. Apparently I was injecting into a function. I'm sorry about that.
