    NOTE: if you're trying to DLL Inject an 32 bit game, compile the code AND the DLL in 32 bit. This will save you A LOT of debugging hours.
    PD: Very nice tutorial! thanks to you i was motivated to pickup a very old project, which extends the functionality of an old but loved game of mine (Burnout Paradise)

    feedback: you have an icon for a questionmark and a checkmark. whenever you come up with an idea, you use the checkmark, as if you had already finished the execution of said idea. it would make more sense to introduce a lightbulb or a though bubble icon whenever you talk about a new concept/idea.

    Nice video! A few criticism that I hope to be constructive: I would point out why you created a thread after the injection. I would say that writing with pointers is cleaner and gives the viewer a better understanding of whats going on but doesn't really matter

      Great point! I'll use pointers moving forward, a few people have made a similar comment.

  • @dasphantom0439
    @dasphantom0439 3 роки тому +7

    So why do you need to use the WriteProcessMemory and ReadProcessMemory functions? The DLL is running directly in the memory of our game so. Why are we not able to treat the address like a pointer and directly write/read to it?

    • @247CTF
      @247CTF  3 роки тому +2

      Good point! As long as we can write to that memory location we can use more native functions. WriteProcessMemory handles some of the leg work for us automagically if it's not, so for a beginner video this was an easier approach!

    Great tutorial!
    I wonder what machine you used to test the DLL injection, because I'm running into a problem with CreateRemoteThread(). Both my DLL and Injector are 32bit running on Windows 10 and I received Access Denied Error with the function. :((

    • @247CTF
      @247CTF  3 роки тому +3

      The code in the video is 'bad', there is no error checking on the responses from the function calls - you should start there and use GetLastError to try and find the problem. If you have an EDR or similar running on your system, that may be blocking these types of calls too.

    Let's say a game is running in unreal engine, and want to access the debug console. However, after injecting my script, and checking the log Im told console wasnt able to be reenabled due to code not being present. Is the code set by the devs, or is it more of a universal code? Also could you say examine the executable in a hash editor and maybe discover said code? Like it has to be in a mem block at some point right?

  • @ruadeil_zabelin
    @ruadeil_zabelin 4 місяці тому

    Wouldn't piggybagging on one of the existing dll's be better? So for example it probably uses winmm.dll or some d3d dll. If you put that in the same directory as the executable; it'll get loaded first. You stub/forward all the functions and put your own stuff in one of the ones that gets called. That way you don't need admin elevation to inject yourself into the other process

    • @247CTF
      @247CTF  3 місяці тому

      That is another option sure, but you don't need admin rights to inject into another process you own

    instead of using hardcoded patch size you could utilize vectors which automatically resize themself to match the contents required space :)
    (and why not use an unsigned long long (uintptr_t) for the patch address? It wont be negative and can get really big if you have a lot of RAM available)
    Edit: The amount of ram doesnt really matter, its because of the userland virtual address range
