GamersClub manual maps a module into csgo.exe, I dumped that module from memory.

Here are some interesting string objects.

They appear to hook LdrLoadDll, not sure why they don't just use a MiniFilter since they already have a kernel-driver but they're not very good at their job so I'll just assume the reason is incompetence.

.rdata:100AB8B0 0000000A C ntdll.dll
You can also see that they monitor the source engine for unauthorized modifications or activities.

You can see from these strings that they take screenshots of the game window using Direct3D.

.data:100B1000 00000014 C rfaceToFileInMemory
The module also uses LibCurl, it seems to forward certain things to a web API and the module can make connections to an FTP server and/or a Mail server (I doubt the mail server connection functionality is used, I think it's just part of a library they use)

So the injected module appears to be able to do a couple of things.
Take screenshots of the game surface using Direct3D SDK
Monitor the Source Engine for unauthorized hooks or activities
Hook LdrLoadDll for DLL whitelisting
Upload suspect binaries/memory to an FTP server/web API

These are the main functions it appears to be capable of, it can do a few more standard anti-cheating things, but nothing interesting or otherwise worth noting.
