Activison own answer to cheaters and hackers on Call Of Duty called Ricochet did have quite a difficult 1st year and beginning of the second one. Going through mid Year 2 however, they have pressed up.

Activison confirmed that the newest update on their anti-cheat Ricochet contains solutions that disallow cheaters on using inappropriate hardware that while is not the same as cheating, will give some Call Of Duty players some unfair advantages.

Mainly, it targets third-party devices to cheat in Call of Duty multiplayer, using specific controllers on PC and consoles including PS5 and PS4.

Call Of Duty Modern Warfare 2 Warzone Caldera, Vanguard and Warzone 2.0 will make a first warning to players using an inappropriate controller and insistence of player on keep using it, will lead to to suspensions, bans, and mitigations, which as previously reported includes giving non-cheaters god mode, making them invisible to cheating players, and disarming cheaters of their weapons.

Ricochet will be going after account boosting, intentional game glitching, and player griefing. The game will send warnings to players if their account has been reported for any behavior against a sane playthrough of Call Of Duty.

Ricochet developers has also announced that it will automatically capture and store all match data of potential cheaters and of matches in the highest tiers of ranked play. This will make it easier to identify and investigate cheaters, and hopefully make the leaderboards more legitimate than before.
