Luckily, Valve released the source code (called the sdk) to Half-Life which CS is a mod of. The DLL then has access to all the game’s memory and can do whatever you want it to do granted you know how to do it. The injector is a program that allocates space in the target process (the game) and then calls the win32 api CreateRemoteThread function to start execution of the DLL file.

Here’s how it works and how to extend it in case there’s anyone out there that has an interest and a little more time than I do right now. It wouldn’t be too hard to extend the hack into something like a wallhack or an aimbot. It’s only a no-flashbang hack, but all of the dirty work is done. I did some reading and then wrote an internal hack with some help from forum posts on. After trying and failing to hack this game on and off for almost 15 years (I started playing young), I finally had enough background in C, assembly, and operating systems to pull it off.
