VALORANT Anti-Cheat Driver Explained

A post from Riot on Reddit chimes in on a discussion of anti-cheat measures in VALORANT, their new first-person shooter (thanks DSOGaming). This explains why they are loading a driver at boot and what it does and does not do. Here's word:
TL;DR Yes we run a driver at system startup, it doesn't scan anything (unless the game is running), it's designed to take up as few system resources as possible and it doesn't communicate to our servers. You can remove it at anytime.

Vanguard contains a driver component called vgk.sys (similar to other anti-cheat systems), it's the reason why a reboot is required after installing. Vanguard doesn't consider the computer trusted unless the Vanguard driver is loaded at system startup (this part is less common for anti-cheat systems).

This is good for stopping cheaters because a common way to bypass anti-cheat systems is to load cheats before the anti-cheat system starts and either modify system components to contain the cheat or to have the cheat tamper with the anti-cheat system as it loads. Running the driver at system startup time makes this significantly more difficult.

We've tried to be very careful with the security of the driver. We've had multiple external security research teams review it for flaws (we don't want to accidentally decrease the security of the computer like other anti-cheat drivers have done in the past). We're also following a least-privilege approach to the driver where the driver component does as little as possible preferring to let the non-driver component do the majority of work (also the non-driver component doesn't run unless the game is running).

The Vanguard driver does not collect or send any information about your computer back to us. Any cheat detection scans will be run by the non-driver component only when the game is running.

The Vanguard driver can be uninstalled at any time (it'll be "Riot Vanguard" in Add/Remove programs) and the driver component does not collect any information from your computer or communicate over the network at all.

We think this is an important tool in our fight against cheaters but the important part is that we're here so that players can have a good experience with Valorant and if our security tools do more harm than good we will remove them (and try something else). For now we think a run-at-boot time driver is the right choice.

So Valorant is messing up other games and the devs/support are trying to hide this issue.. pretty scummy

I wonder if they can get Valorant working on Linux?

Thats actually a really good idea. Let Microsoft manage a kernel extension(?) instead of each company installing their bloat

@jdreyer - When the sub first stood up, they handpicked their own moderators who have demonstrated in the past that any criticisms get squashed.
@Bhruic - you do realize that the bug is related to a piece of software that nobody wants as an anti-cheat mechanic in the game, right?
"well it's a bug"

On a piece of software running on Level 0.... from China.. not remotely acceptable. Then after you uninstall the game, it's still there.

If you dont think that they moved the bug and wont allow the discussion of the software anywhere else because "it's just a bug"... youre either a china or riot apologist, and neither are good to be.

You think Tencent is going to allow any discourse about their game on a website that they own part of? HAHAHA! Yeah, sure they will!

[url=]https://www.fool.com/investing/2019/02/08/tencent-invests-social-platform-reddit.aspx[/url]

Lets see if in a few days, weeks etc.. that this level 0 software concern is still around and discussed openly, or is the moderators who Tencent/Riot chose will decide what people get to discuss on a user-generated content website.

This is almost certainly wrong. See my other post. Or read this if you're still wondering why it's popular among streamers.

Also, this looks nothing like Lawbreakers, other than that both are character based shooters.

As if this is a bug? It's 100% intentionally a design decision, and now the information is mixed in with bugs and no longer a standalone issue. This makes it appear to be something that will be fixed and wasnt supposed to happen. You catching on the agenda there?

Also, that subreddit is moderated by people that Tencent chose to run it as "trusted moderators". AKA- people who will do what we tell them. It's entirely counterproductive to a user-run website to have owners of a product moderating the content.. we can all agree there.

I know you won't believe anything I say, as you are deep in your conspiracy theories, but you are, sadly, wrong. First off, it is a bug, because the title of that post is "Riot's Anti-Cheat software Vanguard is causing frame drops in all my games, including Valorant making them unplayable with the software installed.", and you suggesting that causing frame drops in all games is an intentional design decision is ludicrous. If Vanguard is causing frame issues, it's definitely a bug, and definitely something that (hopefully) will be fixed.

Second, the idea that the moderators were "chosen" by Tencent is laughable. The people moderating /r/Valorant are, by-and-large, people who moderate /r/leagueoflegends. They have been moderating that for longer than Tencent has had any stake in Riot Games. The only way what you are suggesting could be true is if Tencent somehow chose them to be moderators before investing in Riot Games at all, which again is ludicrous. Furthermore, none of the moderators work for Riot Games or Tencent. So the owners of the product most certainly do not moderate the content.

There's no such thing as solid anti-cheat protection that runs on the client and third-party code running with system privilege is just an extra invitation for my system to get hacked.

Any system that requires trusting the client is flawed.
That's why streaming competitive online games will become the standard, once the infrastructure is widespread enough. With no client software on the host machine, there won't be any way to modify the code to make the walls invisible, auto target players, etc.

My own take on this game is that it's another Law Breakers, but some people really seem to like it (although the same was true of Law Breakers). The thing this game has going is timing: it's not really coming out head-to-head with anything else, unlike Law Breakers, which had extremely bad timing.

Do you have any links to share that reveal this information? IMO Occam's Razor suggests that regular Riot employees would be moderating these threads.

Isn't that the point though? Then you're guaranteed to play only with people who aren't interested in cheating, by filtering out people that don't use that system driver (or whatever tech is used).

I do agree cheaters are getting out of hand in games over the last several years though. Really annoying. Bad enough to warrant region locking in pretty much anything competitive, but I'm not sure what games actually do that.
How would region locking help with cheating? Are there nationalities out there that don't cheat at all?

Do yall think the developer is paying the streamers?

There are not paying the streamers to play it. There are plenty of reputable streamers playing the game who would notify their viewers when they are playing a sponsored game. Streamers are playing it because there is record breaking viewership for the game right now, with top streamers routinely racking up 200k+ concurrent viewers. This is because watching a drop enabled stream on Twitch is the only way to get a beta key right now.

There was a scandal recently when a big streamer Dr. Disrespect pretended that his stream had beta key drops enabled when it wasn't. The devs approached him initially to stream the game, but he wasn't interested because they weren't offering him any money. Now he's jealous of the attention other people are getting and lied to get more views.

Some of them I don't see playing the game and they aren't all that excited while they are playing.....

I don't see this game hanging around.

That's because many streamers have been playing the game every waking hour. it's probably hard to stay excited after one week of playing the same 3 maps 16 hours a day. Every current or ex CS pro that I've watched had positive things to say about the game, and with Riot's plan to constantly update the game like LoL, you can bet the game will be around for a LONG time. Whether the game can overtake CS:GO, now that's a more debatable question.

What tells me it is out of control is the length of time it has taken to find the pro cheaters. Scary stuff.

I still run into cheaters in games on the regular. People who say they aren't there either aren't paying attention, never admin'd a gaming server (DOD, CS, etc with tools), played competitively, doesn't know what to look for, or most likely, flat out isn't paying attention.

People are starting to get good at it. The best ones are using teammates who don't get many kills. They then mark or tell their team where the other people are. Starting to see this in CoD, they are getting a lot smarter about cheating.
