Injector

An injector that fetches version.json from a webserver, downloads a dll and injects it into the game.

Setup

To setup the build environment, run the following commands in your preferred terminal.

git clone https://github.com/Yimura/Injector.git --recurse
cd Injector
premake5 vs2019

Get premake5 from here.

Then afterwards open Injector.sln and start coding.

How to use

This injector has 2 ways of functioning:

• Remote mode (webserver required)
• Local mode (inject without webserver)

Setup Remote Server

If you only wish to use the local features just ignore this step and skip to Injector settings.

Requirements:

• Webserver

In the root of your webserver create a file called version.json, this file will tell our Injector what to do and if it should download a dll.

{
	"file": "menu.dll", // path to the dll file on the webserver starting from the root / is prefixed in the binary
	"version": "0.1.3", // human readable version number
	"version_machine": 13 // version number that the injector will compare against
}

Injector Settings

If you run the injector for the first time and no settings.json is present in the folder from which you executed the Injector it will create an example file.

{
    "application_mode": 0,
    "injection_direction": 0,
    "local": {
        "file": "./some_dll.dll"
    },
    "target_application": "wordpad.exe",
    "web_server": {
        "dll_provider": "http://example.com",
        "file": "latest.dll",
        "version": -1
    }
}

Name	Description	Value
application_mode	If the injector runs locally or with a remote server.	WEB_SERVER=0 & LOCAL=1
target_application	The process name of the application to inject into.	string
local.file	The local path to a DLL.	string
web_server.dll_provider	Web Server origin.	string
web_server.file	The file name to save the DLL to locally.	string
web_server.version	Machine version integer to compare with the remote version.	int

injection_direction is currently not implemented, but still exists for future API.

That's it.
