ctivision uses a machine learning system called RICOCHET to automatically detect cheaters in Call of Duty multiplayer. It watches how players aim, move, and behave during a match, and flags accounts that appear to be using software to cheat — like aimbots or wallhacks. It launched in October 2021 and has expanded significantly since 2023.

RICOCHET operates through a combination of a kernel-level driver installed on PCs and server-side machine learning models that analyze full-match behavioral data. Machine learning was formally added to the system in November 2023 for Modern Warfare III, training models to distinguish human play patterns from automated cheating software. By the launch of Black Ops 7 in November 2025, Activision reported a median cheat detection time of under three matches and claimed 99% of beta sessions were cheater-free. The system also includes creative countermeasures — rather than banning cheaters instantly, it can make legitimate players invisible to them ("Cloaking"), show them ghost players only they can see ("Hallucinations"), or disable their in-game abilities ("Disarm," "Splat").
