Injected anti-screengrab DLL- with nothing else added

[-Setro-]

All I want is a simple injectable DLL that stops servers from breaching my privacy by sending them a random image or something rather than my whole screen and any part of steam overlay.
I don't even want this just to cover up hacks, I want this so servers can't snoop through private messages I send to my friends and my browser history. I'm well aware that some injected cheats already have this, but all I want is just the anti-screengrab part.

The only DLL I've found that does this has a broken download link.
All help is appreciated, thank you

No ones going to do it for you.

For c++ hook CMatRenderContext and detour ReadPixels.
For Lua detour render.Capture and render.CapturePixels.

If you don't want them seeing anything you can return an image or return nothing, but that'll get you banned anyway, if you're covering up cheats set up your visuals to disable itself at the time.

Willox has his project that does this archived on his ****** still I believe, if you can't do it yourself.

Garry's Mod can't capture the steam overlay anymore. It was patched in the most recent update, OP. Educate yourself before starting a thread, please.
