| | After my recent blog post, my old mate @_Dark_Knight_ reached out to me and he asked me a question: "Do you typically callout user apps that allow dyld_insert_libraries?" And a few similar ones, and I will be honest, I had no idea what is he talking about, if only I understood the question :D Despite the fact that my recent blog posts and talks are about macOS, I deal much more with Windows on a daily basis, probably like 95%, and macOS is still a whole new territory for me. So I decided to dig into the question and learn a bit more about this.

We'll walk though the lower-level details of what makes up a Mach-O file, how dyld processes load commands to map areas into memory, and how we can emulate this to avoid writing payloads to disk.
