vTables for Game Hacking & VMT Hooking

🔥 Learn How vTables are used in Game Hacking & VMT Hooking

📜 Video Description:
Welcome to this instructional video presented by guidedhacking, where we take an in-depth look at reverse engineering techniques in game hacking, specifically using C++. Our focus here is a detailed game hacking tutorial in C++, where we illuminate how to bypass anti-cheat systems using V cable swapping, VMT function pointer hooking, and much more.

Kicking off this C++ game hacking tutorial, we provide an insightful explanation on the concept of vtables. A vtable, or virtual method table, is fundamentally an array of function pointers. We demonstrate the process of determining the function index, which forms the basis for function hooking and vtable hooks.

Our journey in reverse engineering continues as we explore how a player class can access functions from an entity class, a cornerstone concept in understanding C++ hooking. We craft a player instance, invoke a function within it, and show how to call this function via the V table indexes, paving the way for vmt hooking. Our VMT hooks tutorial highlights the crucial role of the class instance in accessing the C++ vtables and demonstrates how to print and confirm the correctness of the vtable and function address.

We then move on to illuminate how to use the gathered information to call a function, thus giving a taste of virtual function hooking. This part of the function hooking tutorial involves creating a function prototype, calling the function, and understanding the significance of the 'this' pointer. To further solidify your understanding of function pointer hooking, we demonstrate the necessity of using a class instance when manipulating class properties, which helps avoid exceptions.

The tutorial then delves into VMT hooking, explaining the steps to swap out functions, protect them, and call them again. The c++ game hacking tutorial then transitions into the more complex domain of vtable swapping, an aspect of virtual function hooking that's harder for anti-cheat systems to detect. We provide step-by-step guidance on how to copy and swap the V table, giving a hands-on experience in VMT hooking and vtable hooking.

This vtables for game hacking tutorial concludes by reminding viewers that despite the complexity of vtable hooks, anti-cheats could still detect abnormalities by checking the vtable pointer or each function index. However, equipped with this knowledge and your newfound understanding of vtable hooks, vtable swapping, and function pointer hooking, you're now better prepared to delve into the world of game hacking, reverse engineering, and experiment to your heart's content.

what is a vtable?
A vtable, or virtual table, is a mechanism used in a programming language to support dynamic dispatch (or run-time method binding). It is an array of function pointers that enables a program to select the correct function of an object at run-time.

what is vtable hooking?
Vtable hooking, also known as virtual method table hooking, is a technique used primarily in hacking, where an attacker modifies the vtables of an object to change the object's behavior. The modification often involves replacing a function pointer with a pointer to a function that the hacker controls.

Is a VMT the same thing? Yes!
VMT, or Virtual Method Table, in game hacking, refers to the vtable associated with a particular object in a game. This table contains function pointers that point to the virtual functions used by that object, offering an entry point for hackers to manipulate the object's behaviors.

What is VMT hooking?
VMT hooking in game hacking is the process of modifying an object's virtual method table to change its behavior. This technique typically involves replacing one or more of the object's function pointers with pointers to custom functions created by the hacker.
What is a virtual function pointer?

A virtual function pointer is an element in a vtable that points to a virtual function. Virtual functions are functions that can be overridden in derived classes, and the virtual function pointer allows for dynamic dispatch, ensuring the correct function is called in the context of the object's class hierarchy.
