How Ricochet Anti-Cheat Works in Call of Duty

Ricochet has several parts that work together rather than a single program. Publicly discussed components include a kernel level driver on PC, server side analysis of player behavior, and in match measures aimed at limiting the impact of suspected cheaters on other players. Activision updates these over time, so details can change from season to season.

On PC, Ricochet uses a driver that runs with deep access to the system so it can detect tampering with the game. This is why some players see prompts or errors related to the driver, and why outdated Windows installs or conflicting software can occasionally cause problems.

Server analysis looks at how players move, aim and behave in matches. The idea is that behavior patterns can reveal advantages that do not look like normal play. Because this happens on Activision's servers, it does not depend on the player's machine.

Activision has described mitigations that can alter the experience for suspected cheaters before or alongside bans. The goal is to reduce the harm done to legitimate players while evidence is gathered. Specific mitigations have changed over time.

Bans can be temporary or permanent and may apply to an account, and in some cases to hardware. Penalties are enforced under the Call of Duty security and enforcement policy, which you can read on Activision's support site.

Mistakes are rare but possible, for example when a shared account is misused or something on your PC triggers a false flag. If you believe your ban is a mistake:

1. Check the ban notice and the details in your Activision account.
2. Submit an appeal through Activision's official support channel.
3. Provide accurate information about your account and hardware, and do not exaggerate.
4. Remove any software that could interfere with the game while you wait.

Expect the process to take time, and be wary of anyone offering paid shortcuts to get a ban removed.

If you see suspicious play, use the in game report option on the player and after the match when available. Reports are one of the inputs used to review accounts.

Use two factor authentication, keep Windows and your graphics drivers up to date, and avoid sharing your account. If your PC runs well, you reduce the chance that driver conflicts disrupt your matches. Our guide to boosting FPS in Warzone is a good place to start.
