wtf is extremeinjector?

ExtremeInjector is a Windows tool that loads a DLL file, a kind of shared code library, into another already running program. This technique is called DLL injection and it is used by game modders to add unofficial features to a game while it is running, and by developers who want to attach debugging code to an application without changing its original files. The tool supports several different injection methods, including a technique called Manual Mapping and a stealthier mode meant to be harder for anti-cheat systems in online games to detect, alongside more standard loading methods. It works with both 32-bit and 64-bit programs, lets you pick a running process from a list, and performs the injection with a single click, from a lightweight, portable application that needs no separate installation. Using it means downloading the release archive from the project's GitHub page, extracting it, and running the included program as an administrator, then selecting the target process and the DLL file to load. The README notes plainly that antivirus software will almost always flag DLL injectors like this one as suspicious, since the underlying technique is the same one malicious software often uses, and it recommends downloading only from the official repository, scanning files with VirusTotal, and adding an exclusion in your antivirus if you trust the source. Because this tool can bypass anti-cheat protections in online games, using it in multiplayer games will typically violate that game's terms of service and can lead to a ban, separate from whatever a game's developer might do to detect it. It is best understood as a general purpose modding and debugging utility rather than software built for a single specific game. The project is released under the MIT license.
