 Posted: Fri Feb 11, 2022 3:11 pm Post subject: Is it possible to directly inject bytes from an AOB |
 |
|
All I'm interested in is the disassembly of this AOB:
```
57 56 5f 5e 48 31 c0 48 89 f0 48 01 f0 48 05 00 04 00 00 48 81 ef 00 01 00 00 48 01 f8 c3
```
My thought process was: "Damn, I have a pretty sweet x64 disassembler right here in CE! I can get the whole function that way!"
but I'm having a hard time getting these bytes into the disassembler.
Any thoughts on how to do this? |

If that AoB actually exists in the game, then just go to that address in the disassembler.
If it doesn't, then allocate some memory (or find a code cave) and write the bytes to it. e.g.
| Code: | globalalloc(foo,4096)
foo:
db 57 56 5f 5e 48 31 c0 48 89 f0 48 01 f0 48 05 00 04 00 00 48 81 ef 00 01 00 00 48 01 f8 c3 |
PS: you're exchanging rsi and rdi with those push/pop instructions.

I usually take a whole copy of the code (using readmem), and I add the instructions I want in a cave.
If you want to write directly, do as ParkourPenguin suggested: define the bytes somewhere and make sure it's written to address you want. Although the address could be the actual process, it does not have to be allocated memory. (meaning, instead of 'foo' you put there myprocess.exe+592850 or something) |
