Activision has been pursuing cheaters for awhile now, after issuing a stern warning a few years ago that cheaters aren't welcome. The Ricochet anti-cheat system arrived in 2024 with a kernel-level driver designed to catch PC cheaters developed internally for the Call of Duty franchise by Activision.
The driver monitors the machine and processes interacting with a game using RICOCHET Anti-Cheat to determine if they are manipulating the game. This data helps identify cheaters as well as helps the RICOCHET Anti-Cheat team to strengthen the overall anti-cheating security.
