![]() ![]() Software that runs at the kernel level has the greatest level of control over your PC. It's the core of your operating system, where the most basic functions happen, such as allocating system memory to different programs. If we were in a '90s hacker movie, the kernel would be the virtual reality sphere of green code where the final showdown takes place. What does it mean that the Vanguard driver is "kernel-mode"? That's why you have to reboot after installing Vanguard. If Vanguard's driver isn't started with Windows, Valorant won't trust your PC, and you won't be able to play. It doesn't collect data about your PC or send anything to Riot: It looks at other drivers and blocks them from running if it detects that they have a known vulnerability that could be used to compromise the anti-cheat client. (Vanguard blocks fewer programs as of an update in May, and in the future may prevent Valorant from running instead of blocking the offending software.) The kernel-mode driver is the client's bodyguard, basically. A client that checks to make sure you aren't running any cheats while you're playing Valorant.A kernel-mode driver that runs when your PC boots up.However, this special scope for Vanguard and the higher bounties that come with it is indeed new, and clearly an attempt to convince sceptical PC gamers of Riot's commitment to protecting user data, while keeping its anti-cheat competitive. Riot's use of HackerOne isn't new - it has run a bug bounty program on the website for the past six years, rewarding hackers almost $2m in bounties. "If you're able to help us protect our players and their data by responsibly identifying new security issues for us to fix, you are awesome and we want to reward you." Let's Play Valorant Closed Beta - VALOR-CAN'T? "To reinforce our commitment to our players' security, we are offering special bounties for up to $100,000 for high quality reports that demonstrate practical exploits leveraging the Vanguard kernel driver," Riot said. The maximum reward is $100,000, which relates to code execution on the kernel level that involves a network attack with no user interaction. It listed a handful of Valorant-specific bounties on HackerOne, a website where companies can offer rewards to hackers who expose security issues in their software. However, Riot has also taken the extra step of offering a huge bounty pot for Vanguard exploit reports. "Riot does not want to know more about you or your machine than what is necessary to maintain high integrity in your game," Riot said. Riot then insisted Vanguard does not collect or process any personal information beyond what the current League of Legends anti-cheat solution does, and revealed the Vanguard driver (kernel-mode) is used by the client to validate memory and system state, and to make sure the client has not been tampered with. For example, some of the more advanced cheating communities have used Direct Memory Access (DMA) to rebroadcast memory to a separate computer for later processing." Valorant PC Beta Tested: Max Settings on GTX 1060 and RX 580 Without revealing exactly how Vanguard works, Riot explained its decision in a blog post: "If anti-cheat software is only run in user-mode, its capabilities would be compromised by a cheat running at a higher privilege level. The recent release of competitive PC shooter Valorant in closed beta form was accompanied by the release of Riot's new anti-cheat solution, dubbed Vanguard.Įarlier this month, fans raised concerns about user security and privacy after discovering Vanguard is more invasive that other anti-cheat solutions.Ĭurrently, if you download and play Valorant, then Vanguard is automatically installed on your computer, and it always runs with high privileges (the driver component runs in kernel-mode, as opposed to user-mode). ![]() Riot has offered hackers up to $100,000 to find vulnerabilities in Valorant's controversial anti-cheat. ![]()
