Activision has introduced new RICOCHET anti-cheat detections targeting Direct Memory Access (DMA) cheats in Call of Duty: Modern Warfare 4, with the protections going live ahead of DMZ Early Access earlier this week.
DMA cheats use external hardware to access game data that should remain hidden from players, including the positions of opponents. Since these devices operate outside the PC running Call of Duty, they can evade traditional software-based anti-cheat systems.
The Call of Duty team confirmed the new detections in a series of posts on social media, saying the measures were already drawing complaints from cheating communities. Activision plans to keep refining the system as cheat developers modify their methods to avoid detection.
The publisher described DMA detection as an additional layer in RICOCHET’s anti-cheat tools for Modern Warfare 4. The team also confirmed that protections will continue to evolve throughout the game’s lifecycle, with DMZ Early Access serving as the starting point for further work.
Activision also addressed issues affecting players who are having trouble with secure attestation requirements. The company has updated its secure attestation wizard to help resolve some of the more common problems reported by players.
According to the update, AMD 3.x.0.x is currently the most frequently reported issue, while Lenovo users are experiencing problems at higher rates than users of other manufacturers. Players using Lenovo devices who cannot find the required BIOS update are advised to contact Lenovo directly, as the company has not made the update publicly available.
The anti-cheat changes arrive as Call of Duty: Modern Warfare 4 launches, with Activision pledging to adapt its detection methods as cheat developers attempt to work around them.
