Learn how to talk directly to the machine. Master user-space internals, memory mechanics, and the boundary where software meets the OS.
process_vm_XXX Part4Before continuing learning about process_vm_readv and process_vm_writev we'll stop for a second and analyze how everything we've learned so far related to the domain of binary exploitation. First we'll use them to hack our own game and once hacker we'll write a trainer also using these system calls. Later we'll see how to use them to steal credential from process memory.
ptrace Part3Third and last part of chapter 1 with the final chapter project. We implement the nanomites protection system. Invented in the 90s is still a powerful way to slow down reverse engineering your project.
It is very easy to add a library to a program using LD_PRELOAD, but whatif you want to unload that library after performing some task?

In hacker circles, heavy wizardry means code that trades on intimate knowledge of a system—the kind that speaks its private dialects and bends its rules. Heavy Wizardry 101 teaches you to write it. You’ll build shellcode, backdoors, droppers, and worms from scratch, working at the instruction level where magic happens.
A streamlined, unbloated reference guide to the most powerful utilities in the GNU/Linux ecosystem. Learn to navigate, pipe, and automate your workflow like a Unix veteran—one daily command at a time.
