Adding Functions Gunz.exe

[JoshA56]

I want to add the following code into Gunz.exe

shell "program.exe"

I was thinking of somehow editing the EP to a codecave where the code could be executed, then jumping back to the original EP, but I'm not sure how that would be done.

Any help would be appreciated, thanks.

You need to do it in asm ... JMP to code cave then ...

PUSH Gunz.********                       ;  ASCII "program.exe"
PUSH 5                                   ; /ShowState = SW_SHOW
LEA ECX,DWORD PTR SS:[ESP+14]            ; |
PUSH ECX                                 ; |CmdLine
CALL DWORD PTR DS:[<&KERNEL32.WinExec>]  ; \WinExec

Then JMP back up to your code ...
