What is RICOCHET Anti-Cheat?

RICOCHET is Activision’s anti-cheat system designed to detect and prevent unfair gameplay. It operates at a deep system level and continuously monitors gameplay and system behaviour.

• Kernel-level components
• Real-time monitoring
• Hardware-based tracking

How Warzone Uses HWID Bans

Warzone uses HWID bans to prevent players from returning after account bans. Instead of just blocking accounts, it can identify the device being used.

• Tracks multiple hardware identifiers
• Links multiple accounts to one device
• Blocks repeated access attempts

---

TPM & Secure Boot in Warzone

Modern systems use TPM (Trusted Platform Module) and Secure Boot to verify that your system is running in a trusted and unmodified state.

• Ensures system integrity
• Prevents low-level tampering
• Supports secure verification

---

Detection Methods Used

• Hardware fingerprinting
• Behavioural analysis
• System integrity checks
• Cloud-based verification

These combined methods make detection more advanced compared to basic anti-cheat systems.

Recent Updates in Warzone Anti-Cheat Systems

Modern anti-cheat systems in Warzone continue to evolve with stronger verification methods and account security requirements.

Phone Number (SMS) Verification

In competitive and ranked environments, players may be required to verify their account using a phone number. This helps reduce the creation of multiple accounts and improves accountability.

• Links accounts to real users
• Reduces repeat account creation
• Common in ranked or competitive modes

System Integrity & Attestation

Modern anti-cheat systems may use system integrity checks and secure verification methods to confirm that a device is running in a trusted state.

• TPM (Trusted Platform Module)
• Secure Boot verification
• Cloud-based system validation

Some systems may use cloud-based attestation technologies to validate system integrity in competitive environments.

Continuous Anti-Cheat Updates

RICOCHET is regularly updated to improve detection methods and adapt to new threats.

• Real-time monitoring improvements
• Behavioural detection updates
• Hardware tracking refinements

---

What This Means for Players

• New accounts may still be restricted
• Device-level bans are more effective
• Competitive modes have stricter requirements
• Anti-cheat systems continue to evolve
