Riot Games faced scrutiny in 2020 for implementing a similar kernel-level driver in Valorant, though the main issue was that it was always on, operating even when the game wasn't active. While operating in the kernel isn't uncommon for anti-cheat software, this is likely the most concerning part of Activision's new plans for many players. The Ricochet Anti-Cheat kernel-level driver will only turn on when Warzone or Vanguard is active it's not an always-on situation. The kernel, or ring 0, is the most privileged level of any PC, granting access to every layer of hardware, and generally reserved for things like graphics card drivers and trusted bits of the operating system.

The second prong is a PC kernel-level driver designed to monitor the deepest level of every player's rig while they're in-game, in an effort to stop outside software from sneaking in through this back door.

These new server tools will be live in Vanguard when it comes out on November 5th. The first stage is a series of server-side enhancements that will better identify and remove cheaters from games, and this is scheduled to hit Warzone with the Pacific update later this year. The PC kernel-level driver monitors and reports applications that attempt to interact with Call of Duty: Modern Warfare II, Call of Duty: Warzone 2.0, or Call of Duty: Vanguard, allowing the RICOCHET Anti-Cheat team to determine if a machine is utilizing unauthorized processes to manipulate the game.Activision has unveiled its big, new approach to squashing hackers in Call of Duty: Warzone and Vanguard, and it's a two-pronged system called Ricochet Anti-Cheat. HOW DOES THE RICOCHET ANTI-CHEAT KERNEL-LEVEL DRIVER WORK? The driver has deployed globally for Modern Warfare II, Vanguard, and Warzone 2.0. Each title also utilizes a new PC kernel-level driver for all players, developed internally for the Call of Duty franchise. RICOCHET Anti-Cheat’s backend anti-cheat security features have launched for Call of Duty®: Modern Warfare® II, Call of Duty®: Vanguard, and Call of Duty®: Warzone™ 2.0. The RICOCHET Anti-Cheat initiative is a multi-faceted approach to combat cheating, featuring new server-side tools which monitor analytics to identify cheating, enhanced investigation processes to stamp out cheaters, updates to strengthen account security, and more.
