This article discusses one of the most sophisticated PWN topics: kernel exploitation in Linux. You are about to learn what tools are required for kernel debugging, what are LKM, KGDB, IOCTL, and TTY, and many other exciting things!

This article covers the following topics: memory management algorithms in Linux, heap exploitation techniques, and exploitation of the Use-After-Free (UAF) vulnerability on a host where all protection mechanisms are enabled. The target machine is RopeTwo, one of the most hardcore VMs on Hack The Box.

No, this article isn’t about motor cylinders and valves – it’s about Google V8 Engine used in Chromium and Android. Today, I will show how to hack it on RopeTwo, the most hardcore VM on Hack The Box. Concurrently, you will learn what types of data are used in this engine, how to manipulate them in order to drop an exploit, how to use V8 debugging tools, what it WebAssembly, and how can it be used to penetrate into the RopeTwo shell.
