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)
Cheers dude! I'm currently writing a mod engine for a game with a friend and because of you i can start learning c++ the way i like (by doing stuff) :D
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.
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?
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!
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
How do you locate the address of the patch without knowing it in the first place? And how do you know what values to overwrite it with to achieve the function you want?
This is where the previous part comes in. Before U inject a dll, u should use cheat engine to make a script. With Dat script, u can then see the bytes of the new opcodes and the adress changed, and there's ur answer
"The error code means an invalid image format. Specifically, you are attempting to start an application which is designed to run on 64-bit operating system. But your computer is running 32-bit Windows."
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?
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. :((
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.
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
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
@@muhammadziyad3648 if the game is fully server sided than there highly likely won't be a lot of useful stuff you can do from the client side. Would recommend to take a look at package modifying or in case you just want to cheat in that one specific game without actually caring about learning that type of stuff, let it be.
@@247CTF 7:54 sure, it's just three simple steps, but it feels like you're going into more complex examples in the future with these "our program will do this/that" explanations.
I hope you still read the comments.. At 05:39, why did you use write process memory instead of memcpy or so, the dll is already executing in the game's memory space, so how come?
No real reason, Windows error codes could be more useful if I handled them. I use memcpy in a different video and someone asked in the comments if I could also use WPM, so I did that in this video instead.
Hey, nice video, I am a total noob with C++, in the Injector.cpp file, on line 28, what is the full line? I tried to figure out that myself but I had no success. Do you mind helping? :D
hey I wanna inject a modded directX dll into a game to force it to run on a lower feature level GPU.. How can I force the game to use it rather than the one in sys32 Is injection the solution? because your injector ran after the game opens But the game in my case doesn't open because it detects a lower FL
It depends a bit on the application.. You might need to binary patch, might not: learn.microsoft.com/en-us/windows/win32/dlls/dynamic-link-library-search-order You could also try a loader like DxWnd
It's a virtual address, not a physical one. So it doesn't depend where into the RAM the process is loaded, it always sees itself with the same addresses.
@@misch2 what do you mean sees itself, when he specifies the exact address. Try to define a variable and it will have different addresses on each run, even if it's virtual memory.
You want to do this with .NET? You can achieve a similar effect but the process is slightly different, there are some examples on GitHub you could check out. The bonus is .NET makes the reversing step easier (usually).
@@247CTF Lua has the ability to require (import) dlls of specific name, for example if a directory is specified it would try to look for directory/init.dll and directory/directory.dll, it will execute a luaopen_directory symbol found in it and pass the lua context which houses global variables and such.
I would expect most modern games would either prevent or detect this naive injection approach. There are methods to block direct DLL injection, but if you can install kernel drivers you could still achieve the same effect! We can explore this in a future video!

Just wanna say your videos are great they combine two great things and hacking the game is just getting your money's worth.
Thanks for the feedback!
Thank you so much I finally understand how byte patching works
I compiled a test dll with visual studio 2022, and the exe is crashing with 0xc000007b error on start, what I am doing wrong?
"The error code means an invalid image format. Specifically, you are attempting to start an application which is designed to run on 64-bit operating system. But your computer is running 32-bit Windows."

Don't know much about Unreal Engine - good luck.
Nice stuff, but you don't actually need to read the original game bytes to toggle the trainer on/off... use the power of XOR :P
Awesome tip! This is a good improvement to the trainer for sure! Will implement this in the next video!

i.e. at 7:00, where did you get all the data for the memory hacks?
Take a look at the previous videos in the series for context!

I thought windows will always give you random memory addresses, but you apply patching to the same address all the time. I don't get it.

Depends if the binary / DLL is compiled with ASLR or not
can i deal with mono.dll like you used the LoadLibraryA and run it in thread inside the target process but i will use for ex mono_get_root_domain ???

Hey yall remember if your directory uses '\'. just make it a raw string like : R"(your string here)";
Also your inner loop for testing is way faster this way.
