[TechSpot] Valorant's anti-cheat software loads kernel-based driver on system boot

Quote:
Riot Games' new team shooter Valorant has an anti-cheat system called "Vanguard" that has raised some security concerns. When the game launches, the Vanguard client loads with it into the userspace. However, there is a kernel-mode driver for the system that loads when you boot into Windows.

Riot claims that it needs this since some cheating software uses kernel-mode drivers to evade detection. Regular applications cannot detect kernel-mode drivers because of the higher privileges required.

Back in February, Riot explained the new anti-cheat software, initially designed for use in League of Legends, and why it was needed.

"In the last few years, cheat developers have started to leverage vulnerabilities or corrupt Windows' signing verification to run their applications (or portions of them) at the kernel level. The problem here arises from the fact that code executing in kernel-mode can hook the very system calls we would rely on to retrieve our data, modifying the results to appear legitimate in a way we might have difficulty detecting. We've even seen specialized hardware utilizing DMA1 to read and process system memory—a vector that, done perfectly, could be undetectable2 from user-mode."

Running a driver in kernel-mode raises concerns that Riot is only improving its cheat detection at the cost of increasing the attack surface of Windows, and at the root level no less. If you recall the 2005 Sony DRM rootkit fiasco, this level of risk might make you nervous.

Sounds like they're playing with fire.

Riot who?

The game sounds like a Counter-Overwatch with the graphics of TF.

Doesn't surprise me. Another game i was never going to play anyway as freeware games are full of hackers and cheaters anyway, no matter what anti-cheat they have. PC gaming is the worst, you find more games with cheaters than legit players.
On my Xbox One i had no problems with cheaters.

I like to have fun.

Definitely more cheaters on PC platform, but saying their are more cheaters than legit players is ignorant. Most likely you are just bad at the game.

now now. clearly its just us, and being baddies.

its not noticed on console cuz we're all neutered by thumb sticks and 30FPS!

guarantee the "hax" cries will be yuge, as people play shooters @ 1080P120FPS with KB+M on their XBS/PS5

I do agree though. Theirs an incredibly well funded pay to play "trainer" community these days. It's kinda what caused my MMO burn out. Our progression guild got clued in on how to glitch multiple weapon stones. Low n behold our raid DPS quickly started looking just like the #1 & #2 uncontested guilds.

Add me on Steam, same name

If something appears too good to be true, it probably is.

You ever played CS:GO or BF or even COD? People with obvious walls, i'm just glad that most admins on bf servers don't rely on anti-cheat and deal with it them self.
I'm not saying everyone is a cheater but if you were to say there was only a small community, it just takes that small community of cheaters to ruin a whole game.

if only it were a small community.

you regularly see them willingly revealing themselves in steam discussions. specially in non-competitive titles that happen to have some PvP content as well.

I just don't understand what cheaters gain, like your wasting your life on a game that means nothing anyway. I just wish i understood their motives lol.

idk man. cheating/exploiting always ends up making something incredibly boring for me.

Even in something like Fallout 4. Ran outta mats, too lazy to farm, console command in all the mats i'll ever need, get bored, cuz too easy.

we'll understand why, as soon as we understand why diesel Bros think its cool to Roll Coal.
