Debugger management plugins make it possible to delegate routine debugging and vulnerability identification tasks to the machine. Using practical examples, I am going to demonstrate how to bypass anti-debugging, identify paths to vulnerable functions, and highlight important code sections. You will write a plugin in C++,…

Why automate x64dbg? Because an automated debugger enables you to create custom tools for standard debugging tasks: unpack files, search for signatures, intercept or substitute function outputs on the fly, and even perform fuzzing in RAM! Let’s see how this can be done.

Today I will demonstrate the full exploit development cycle: from creating a fuzzer to shellcode start. The target that will be exploited is a parser of BMP files embedded in GTA Vice City: the game takes these files as user skins. A correctly crafted file should cause…

Angr, a powerful symbolic emulator, makes it possible to seize control over execution of someone else’s code; all you have to do is specify the search direction. Today you will learn how to find similar holes in applications using Angr; in addition, you will write an inline…

This article describes the creation of a Hex-Rays-like decompiler for an exotic programming language used in the game “Pathologic”. You will learn how cross-compilation works and master the basics of the compilation theory so that you can write such a decompiler yourself.

Many years ago, I was eager to understand how the game “Pathologic” actually works. But at that time, the format of its scripts was beyond my capacity. Today, I will show you how to crack the game engine to find out how its scripts operate.…
