Hello guys, i'm relatively new to CE Scripting and i would like to Read the Current Money Value via the Script and it needs to be Editable.

That's what i got so far:

Code: Select all

[ENABLE]
aobscanmodule(pMoneyAOB,Disrupt_64.dll,4C 8B B4 F1 28 07 00 00)
alloc(pMoneyMem,$1000,"Disrupt_64.dll"+5C999C0)

label(code)
label(return)

label(pMoneyChange)
registersymbol(pMoneyChange)

pMoneyMem:

code:
  mov [pMoneyChange],rcx
  mov [rcx+rsi*8+00000728],r14
  jmp return

pMoneyChange:
  dd ?????

pMoneyAOB:
  jmp code
  nop
return:
registersymbol(pMoneyAOB)
[DISABLE]
pMoney:
  db 4C 8B B4 F1 28 07 00 00
unregistersymbol(pMoneyAOB)
unregistersymbol(pMoneyChange)
dealloc(pMoneyMem)

That's a good start but you need to account for the rsi*8 increment. Since this uses two registers I would just use a push/pop and lea on another register to get the final address:

Code: Select all

push	rbx
lea	rbx,[rcx+rsi*8+00000728]
mov	[pMoneyChange],rbx
pop	rbx

If you did not want to use lea for whatever reason, then you could also just use one register:

Code: Select all

push	rbx
mov	rbx,rsi
imul	rbx,8
add	rbx,rcx
mov	[pMoneyChange],rbx
pop	rbx

Which is not pretty but it works at least. Then you just use it as a pointer and add the last 728 offset to it in the table.

I suggest you do better work at it and start learning how to debug/back-trace. Your instruction is "mov [rcx+rsi*8+00000728],r14". Which means one of the registers is a base address, the other is a structure offset. Say your address is 400000. And it's in "rcx". Then your offset to the position is 0 and it's in "rsi". So you get 400000+0*8+728. Now if the offset changes, and instead of a 0, you have 1, then you get 400000+1*8+728. See the dynamics behind it? That spot of yours is recipe for failure. Am assuming game's Watch Dogs, based on the Engine name (Disrupt).

If they found the opcode through 'see what accesses this address' they could check what rsi is equal to and do a compare to always grab the right address though right?
