Call of Duty Anti-Cheat

Kernel Ricochet with HWID bans plus active server-side mitigations like cloaking and damage shields - Warzone, Black Ops 7 and Modern Warfare 4 are a serious target.

In plain EnglishThis page explains the anti-cheat that protects Call of Duty - the system that tries to catch and ban cheaters. It covers how strict that system is and how cheats try to stay hidden from it. No cheat is ever 100% safe, so always check a product's status before you buy.

What anti-cheat does Call of Duty use?

Call of Duty uses Ricochet Anti-Cheat, a kernel-level anti-cheat that loads a Windows driver with deep system access. Caught cheaters get a hardware (HWID) ban on top of the account ban, and our database rates its detection strength high. The guide below covers how it detects, what a ban really costs and what kind of build survives.

Modern Call of Duty - Warzone, Black Ops 7 and Modern Warfare 4 - is defended by Ricochet, Activision’s kernel-level anti-cheat. It also runs one of the more creative server-side mitigation toolkits in the industry. Beyond banning, Ricochet actively messes with detected cheaters: it cloaks legitimate players from their ESP, disables their damage, and uses similar "mitigation" tricks before the ban lands.

That mix of a kernel driver, HWID bans and live mitigations makes COD a genuinely hard target, and the enormous Warzone playerbase keeps it a top priority for Activision.

How Ricochet works in Call of Duty

Ricochet runs a kernel driver that monitors for tampering while the game is open. It is paired with server-side systems that can detect and then quietly sabotage a cheater’s session - rendering them unable to deal damage, or hiding real players from their wallhack. The aim is to gather confidence before a hardware ban. On PC, Black Ops 7, Warzone and Modern Warfare 4 also require TPM 2.0 and Secure Boot, which Activision checks remotely through Microsoft Azure attestation instead of trusting the PC’s own report. Since June 2026 a PC that fails that check in Black Ops 7 or Warzone is moved to a separate matchmaking pool with only a couple of playlists.

This "detect, then mitigate, then ban" approach means a build can appear to work while the server is already neutralising it. As with the other kernel games, "it loads" is not "it is safe."

What a Call of Duty ban actually means

COD bans are HWID plus account: Activision says it issued more than 70,000 new hardware bans in August 2026 alone. New accounts on a banned PC stay locked out, and Activision says its newer protections make spoofers harder to get through, so a spoofer is no guaranteed way back. Since April 2026, free-to-play PC accounts that own no recent COD game also need SMS two-factor authentication, which Activision says is aimed at banned cheaters returning on new accounts.

Activision also runs ban waves and publicises enforcement numbers, so the game is actively, visibly policed. Expect the hardware cost, not just an account swap.

Detection track record

We rate COD "High." Ricochet’s kernel driver plus its mitigation toolkit and ban waves put it above the EAC survival games. Public and free COD cheats are saturated and burned fast.

The mitigation layer is unique. You may notice you "can’t kill anyone" before any ban - that is the server telling you it has already flagged the session. Discretion and a current build are everything. Since February 2026 Ricochet also analyses input timing and recoil patterns to catch machine-perfect aim and recoil from devices such as Cronus Zen and XIM Matrix.

Cheating in Call of Duty safely

In COD the durable approach is a private, maintained build used with restraint - a capped aimbot, ESP for awareness, and recoil control - rather than obvious rage in a streamed lobby. Pair it with an HWID spoofer given the hardware bans.

Check the build’s status before each session, since Ricochet updates frequently. What we keep current for Call of Duty is listed below.

Call of Duty anti-cheat FAQ

Is Ricochet kernel-level?

Yes. Ricochet uses a kernel-mode driver while the game runs, plus server-side mitigations, which is why modern Call of Duty is much harder to cheat in than older, VAC-style titles.

Why can’t I damage anyone before getting banned in COD?

That is Ricochet’s mitigation system. When it detects a cheater it can disable their damage or cloak real players from their ESP to build confidence before issuing a hardware ban.

Does COD need an HWID spoofer?

Often, yes. Ricochet issues HWID-plus-account bans (more than 70,000 new hardware bans in August 2026 alone, by Activision’s count), so a flagged PC stays locked for new accounts. Activision says Azure attestation and its newer protections make spoofers harder to get through, so a spoofer is no guarantee.
