Have you ever wondered what's happening behind the scenes to keep your favorite competitive games fair? It's not just a magical switch; it's a dedicated system designed to outsmart cheaters. Today, we're going to break down exactly how Riot Vanguard operates.
Step 1: The Initial Installation and Its Core Components
The first step in understanding how Riot Vanguard works is realizing that it's not a standalone download. It comes bundled with the Riot Games title you are installing, such as VALORANT or League of Legends. Once you download the game, Vanguard is automatically installed alongside it.
The Two Pillars of Vanguard:
Riot Vanguard is primarily composed of two main parts that work in tandem:
The User-Mode Client: This is the part of Vanguard that runs when you have the game client open. It's responsible for a lot of the anti-cheat detections and communicates with the Riot Games platform to validate your machine. You'll see its icon in your system tray, letting you know it's active.
The Kernel-Mode Driver: This is the most controversial and, in many ways, the most powerful component. This driver operates at the kernel level of your operating system, which is the deepest and most privileged level of your computer. It starts running when you boot up your PC, even before you launch the game.
Step 2: How the Kernel-Mode Driver Maintains a "Trusted" Environment
So, why does Vanguard need to run at the kernel level? To put it simply, modern cheats have become incredibly sophisticated. They can operate at a higher privilege level than regular applications, making them virtually invisible to traditional anti-cheat systems. By operating at the kernel level, Vanguard can see everything that's happening on your system, just like the operating system itself.
On-Boot Operation:
This is a key aspect of Vanguard's design. The kernel-mode driver, often referred to as vgc.sys, loads on startup. This is crucial because it prevents cheaters from loading their malicious software before Vanguard has even had a chance to start. If the driver isn't running from the moment your computer boots, the Riot client will not consider your machine "trusted," and you won't be able to play. This proactive approach is what sets Vanguard apart from many other anti-cheat solutions.
Validating System Integrity:
The kernel-mode driver's primary role is to validate the memory and system state of your PC. It ensures that the user-mode client has not been tampered with and that no unauthorized software is trying to interfere with the game. It doesn't constantly send data about your computer back to Riot; rather, it acts as a guardian for the integrity of your system.
Step 3: Real-Time Detection and The "Cheat-Capable" PC
When you launch a Riot game, the user-mode client and the kernel-mode driver work together to monitor for cheating behavior. This includes looking for things like:
Memory manipulation: Cheats often try to read or write to the game's memory to gain an unfair advantage, like seeing where enemies are through walls.
Aimbotting: Detecting patterns of aiming that are humanly impossible.
Scripting: Identifying the use of automated scripts to perform actions that would be difficult or impossible for a human to do consistently.
The "Restriction" System:
Riot Vanguard has a system in place to detect if a PC is "too cheat-capable." This is a security measure that can restrict access to the game. If Vanguard flags your PC, it will provide a specific error message explaining what settings need to be changed to resolve the issue. This could be anything from disabling certain software that's flagged as a vulnerability to enabling hardware security features like TPM 2.0 and Secure Boot.
Important Note: The Vanguard team has stated that they prioritize user privacy and system stability. They have a bug bounty program to encourage security researchers to find vulnerabilities in their software and offer significant rewards.
Step 4: Troubleshooting and Control
Even with all its power, Vanguard can sometimes cause issues. Riot has made efforts to give users more control over the software.
Disabling and Uninstalling Vanguard:
You can now find a Vanguard icon in your system tray. By right-clicking it, you have the option to "Exit Vanguard." However, keep in mind that doing this will prevent you from playing any Riot game that requires Vanguard. To play again, you will need to restart your computer.
If you want to uninstall it, you can do so through the "Add or remove programs" menu in Windows settings. Just search for "Riot Vanguard" and select "Uninstall." It's important to note that if you have multiple Riot games installed, uninstalling one game will not uninstall Vanguard if another game still requires it.
