However, using this tool to gain an unfair advantage in online games or to deploy unauthorized software on systems you do not own is a violation of Terms of Service and, in many jurisdictions, a violation of computer misuse laws. Further Exploration

This is where the majority of searches lead. Users share compiled binaries with various “improvements” (Stealth features, anti-debug, etc.). —many such files include keyloggers, clipboard stealers, or crypto miners.

Today, Kdmapper is a classic piece of software history. Microsoft and game developers have worked to "blacklist" the vulnerable Intel drivers it relies on. While newer versions and "forks" of the tool continue to pop up, using it remains a high-risk activity that can lead to permanent hardware bans in games or severe system instability (the dreaded Blue Screen of Death).

The original project (by hfiref0x and contributors) is called (Kernel Driver Utility) or forks like “Kdmapper” by other devs. The legitimate source code is available on GitHub. However:

(Kernel Driver Mapper) is a tool utilized to manually map kernel drivers ( .sys files) into the Windows kernel space.

On the drive there was not a tool but a confession: a README that told of a kernel-mapping experiment that had become more than the sum of its parts. The author wrote in a voice that was neither youthful nor old, a tone that mixed apology and amazement. They described a moment when a utility they had intended as a microscope had instead become a mirror. The README did not absolve. It asked: if you can see the core of something, what do you owe it? How does one repair harm that is a byproduct of understanding?
