basic loader (32bit/64bit)

[icrypto]

I just added 32bit. Since I don't use 64bit, I don't have a chance to try it.

 
 

;
; This is a very basic loader without Address Space Layout Randomization support.
; It Can build to produce 32bit or 64bit application (MASM32 or MASM64)
;

ifndef _Win64
include masm32rt.inc
else
include masm64rt.inc
endif
 
.const
    filename          db "test.exe", 0
    targetaddress     dd 4012D8h
    values            db 1 dup(74h)

    sinfo STARTUPINFO<>
    pinfo PROCESS_INFORMATION<>
 
.code
    start proc
        invoke CreateProcessA, addr filename, NULL, 0, 0, 0, CREATE_SUSPENDED, 0, 0, addr sinfo, addr pinfo
        invoke WriteProcessMemory, pinfo.hProcess, targetaddress, addr values, 1, NULL
        invoke ResumeThread, pinfo.hThread
        invoke ExitProcess, 0
        ret 0
    start endp
end

 

! Ok
.I Can't download your attachment yet, but I adapted my sample to work with your provided address of [test.exe] application

.Attached 32bit and 64bit build from my previous code
