Hi

I have a program that store the variable on a random position every time. I use Aobscan() to get the correct offset, this works very well:

Code:

[ENABLE]
alloc(newmem,2048)
label(returnhere)
label(originalcode)
label(exit)

label(what)
registersymbol(what)

aobscan(aob1,89 56 34 C7 45 FC 00 00 00 00)

newmem:

originalcode:
mov [esi+34],edx
mov [ebp-04],00000000

exit:
jmp returnhere

aob1:
what:
jmp newmem
nop
nop
nop
nop
nop
returnhere:

[DISABLE]
dealloc(newmem)
what:
db 89 56 34 C7 45 FC 00 00 00 00
unregistersymbol(what)

This piece of code works. Now I want to create a new label (registersymbol?) and store the address [esi+34], then show on the CE Table like this:

I want to know how to show the [esi+34] value on the (addr) label every time the script is ON.

I tried something like this:

Code:

[ENABLE]
alloc(newmem,2048)
label(returnhere)
label(originalcode)
label(exit)

label(what)
registersymbol(what)

label(addr)
registersymbol(addr) //Here I want to move the address value and show on the table

aobscan(aob1,89 56 34 C7 45 FC 00 00 00 00)

newmem:
addr:
mov [addr],esi //I have no idea what I'm doing

originalcode:
mov [esi+34],edx
mov [ebp-04],00000000

exit:
jmp returnhere

aob1:
what:
jmp newmem
nop
nop
nop
nop
nop
returnhere:

[DISABLE]
dealloc(newmem)
what:
db 89 56 34 C7 45 FC 00 00 00 00
unregistersymbol(what)
unregistersymbol(addr)

If I exec the script, the (addr) address on the table fill up with an address, but is not the esi value, so I assume that I do it wrong.

Someone can explainme how to do it? Thanks Smile

and add a new address named "stuff"

No problem. What does, "it didn't work" mean? If your original script worked, I don't see any obvious reason that the updates I made should break it. Of course, I elided the [disable] section, but...
