    I decided to commit another part to the Applied Reverse Engineering series with an article diving into rolling your own primitive tracer for discrete purposes; coupled with an analysis on outrunning integrity checks.

    We need less tech e-journals / “tech news curators” with incompetent owners/writers. It’s on par with the drivel and saturation of Podcasts these days. Where in this did Microsoft say they are removing kernel access for 3rd parties? Where in their official statement? Their

    I got time to update a draft that should've been published long ago. Here is a fun PG-compliant hooking mechanism, and the example covered in the article is system-wide SYSCALL hooks in a PG-compliant manner.

    Part 2 of Accelerated Assembly. Take a real target and learn more assembly in the deep end (without your floaties). Learn various techniques to make analysis easier, and hopefully, inspire you to go out on your own!

    It's been a long time coming, but I'm publishing the first two parts of the EPT series. I will update this thread with links to the posts as I publish them. They're long, but hopefully comprehensive enough for even the most unfamiliar to implement EPT.
    revers.engineering
    MMU Virtualization via Intel EPT - Index - Reverse Engineering
    EPT, EPTP Switching, Page Hooks, and much more are covered in this 5 part series over hypervisor development. The various examples are tested throughout.
