 |
|
I was wondering,
In Memory View you got that feature to find Assembly code,
Can't we use that in auto assembler?
Like
instead using AoBscan..
we could use
| Code: |
alloc(newmem,2048)
label(returnhere)
label(originalcode)
label(exit)
Assemblyscan(hack,{mov [code..],value
mov value,[code..]
mov value2,value
test value,value2
je Somewhere..})
newmem:
//mov [code..],value
nop
nop
nop
//mov value,[code..]
nop
nop
nop
//mov value2,value
nop
nop
nop
//test value,value2
nop
nop
//je Somewhere, don't jmp to far, so its size is 2 bytes :P.
nop
nop
originalcode:
//mov [code..],value
//mov value,[code..]
//mov value2,value
//test value,value2
//je Somewhere..
exit:
jmp returnhere
hack:
jmp newmem
returnhere:

You know, that would be very inefficient.
There's nice article here:
http://www.strchr.com/machine_code_redundancy
Look at those
03C3 - add eax, ebx
01D8 - add eax, ebx
and those
83C0 01 - add eax,1
81C0 01000000 - add eax,1
05 01000000 - add eax,1
As you see, one code can have more than one opcode.
