 Posted: Sun Oct 23, 2022 1:35 pm Post subject: Script That Allows Setting A Value From Table |
 |
|
Hey guys! I was hoping to learn today how to convert a standard custom AOB script to have an adjustable value you input from the table instead of having 20 clone script of varying values from 1 - 99 (1, 5, 10, 20, 75, 99 etc etc).
| Code: | [ENABLE]
aobscan(INJECT,41 89 46 30 B8 01 00 00 00)
alloc(newmem,$1000,INJECT)
label(code)
label(return)
newmem:
code:
mov eax,(int)9
mov [r14+30],eax
mov eax,00000001
jmp return
INJECT:
jmp newmem
nop 4
return:
registersymbol(INJECT)
[DISABLE]
INJECT:
db 41 89 46 30 B8 01 00 00 00
unregistersymbol(INJECT)
dealloc(newmem) |
The value where you see (int)9 works great but I constantly have to disable the script and enable a different clone script of all the same code with a slightly different value in it's place and it's becoming quite cumbersome. I have no idea to go about doing this, but I'd love if someone could please show me?

Someone posted an almost working example here and received feedback.
In your case you replace the (int) 9 with w/e name you picked inside of []

Thanks a lot @cooleko ! That was just the hint I needed. For search purposes in case anyone else ends up here, this is the code adjustment I got to work:
| Code: | [ENABLE]
aobscan(INJECT,41 89 46 30 B8 01 00 00 00)
alloc(newmem,$1000,INJECT)
label(code)
label(return)
globalalloc(namehere,4)
namehere:
dd (int)0
newmem:
code:
mov eax,[namehere]
mov [r14+30],eax
mov eax,00000001
jmp return
INJECT:
jmp newmem
nop 4
return:
registersymbol(INJECT)
[DISABLE]
INJECT:
db 41 89 46 30 B8 01 00 00 00
unregistersymbol(INJECT)
dealloc(newmem) |
Then just add an address manually called namehere on the main table.

Note that code might not work if the global allocation gets allocated more than 2 GiB away from the code you allocated. (see RIP-relative addressing; only relevant in 64-bit code)
I'd use a label w/ align, but a simple alloc also seems to work... sometimes, maybe. The label is more explicit and hence I like it more.
| Code: | [ENABLE]
aobscan(INJECT,41 89 46 30 B8 01 00 00 00)
alloc(newmem,$1000,INJECT)
label(namehere)
label(return)
registersymbol(INJECT)
registersymbol(namehere)
newmem:
mov eax,[namehere]
mov [r14+30],eax
mov eax,00000001
jmp return
align 4 CC
namehere:
dd 0
INJECT:
jmp newmem
nop 4
return:
[DISABLE]
INJECT:
db 41 89 46 30 B8 01 00 00 00
unregistersymbol(INJECT)
unregistersymbol(namehere)
dealloc(newmem)

The memory record for the value "namehere" can be made a child of the script memory record, and the script memory record can be set to hide children when disabled.
