Hello players,
Over the years, we’ve remained committed to creating a fair and enjoyable gameplay environment, and we’ve made that promise to you time and again.
This August, we’re taking another step toward keeping that promise by introducing a new anti-cheat feature. In today’s Dev Letter, we’d like to share the background and walk you through what’s coming.
The Need for New Anti-Cheat Measures
Recently, cheat tools have been evolving far beyond software manipulation. They now operate at the kernel level, the deepest layer of the operating system, making them increasingly difficult for security solutions to detect.
The kernel level refers to the execution layer within an OS that holds the highest privileges and controls the entire system. Illegal software operating at this level can more easily evade or even disable security solutions.
While PUBG has continuously monitored abnormal activity at the kernel level, the growing number and variety of kernel-level cheats have significantly increased the time and resources needed to analyze and counter these threats.
In response to these changes, we have concluded that it is necessary to strengthen our countermeasures with even more powerful kernel-based features.
Strengthening Kernel-Level Detection With a New Anti-Cheat Feature
As mentioned, kernel-level security features have already been in place. However, we’ve been developing a new feature to provide even more precise and effective protection. Recent internal tests have confirmed the stability and high detection rate of this new feature, and based on these results, we are now ready to introduce this enhanced solution.
The new anti-cheat feature is designed to directly detect abnormal behavior at the deepest layer of the operating system—the kernel level. In other words, even if a cheat attempts to hide itself or launch before the security system in an attempt to bypass detection, it will still be detected.
Once the PUBG client is launched, the new kernel-based anti-cheat feature immediately activates and scans the PC’s kernel for any code suspected of abnormal patterns. If the use of illegal software is confirmed, the player will be kicked and banned from the game.
We expect this new feature to proactively counter advanced cheats, reducing the damage caused by illegal software. It will also allow us to respond more quickly and reliably to cheats that were previously difficult to detect, resulting in a more stable and enjoyable gameplay environment.
Additionally, please note that our anti-cheat solution, including this feature, runs only while the PUBG client is active and will shut down when you exit the game.
Request for Stable Anti-Cheat Operation
If PUBG’s new anti-cheat feature and another external security solution run at the same time, system conflicts or unexpected behavior may occur. This is not due to any flaw in PUBG’s security system itself, but rather a normal interaction between different security programs.
Each security application inspects system memory and processes in its own way, so running two or more game clients simultaneously can cause their anti-cheat modules to clash or interfere with one another, potentially causing unexpected issues during launch or gameplay.
To prevent this issue, starting with Update 37.1, if PUBG and another game client with its own security software are both running, a warning message may appear when you enter the lobby. If you see this pop-up, we recommend closing one of them and running only one client at a time.
This measure is intended to ensure a more stable environment and minimize in-game disruptions caused by software conflicts. We appreciate your understanding and cooperation.
Concluding Today’s Dev Letter
This new kernel-based anti-cheat feature is PUBG’s latest core measure for responding to advanced threats. We will continue to develop and apply a wide range of security technologies. This is more than just a feature update—it serves as a foundation for building a sustainable security framework.
Moving forward, in line with our 2025 Anti-Cheat Roadmap, we will advance our illegal software countermeasures by combining technological innovation with operational efficiency.
We will continue to listen to your valuable feedback, and do our utmost to provide a fair and trustworthy gameplay environment.
We’ll see you in the next Dev Letter.
