I've been messing with kernel-mode anticheats for 3 to 4 years so yah, not something a typical gamer can do. But I have been contempating on making this publically available for everyone to use wrapped in a neat little package!
You definitely should! Even just a blog post about it would be great. I won't be doing it myself, but my son would for sure.
Out of curiosity do you run the backdoored kernel in your day to day computing or only when gaming? Any concerns about incidental security issues?
