# NextHooker



## Overview

*NextHooker* is an open-source x86/x64 text hooker for Windows.

![How it looks](https://media.discordapp.net/attachments/330538905072041994/486629608456847360/unknown.png?width=1083&height=353)

Basically, GUI text hooker based on [Stomp](http://www.hongfire.com/forum/showthread.php/438331-ITHVNR-ITH-with-the-VNR-engine)'s ITHVNR.

- Open-source
- x64 supported (x64 version only works with x64 programs)
- Hook text using /H "hook" codes (most AGTH codes supported)
- Directly read text using /R "read" codes ([Guide](https://www.youtube.com/watch?v=AcEgjCoww5w))

## Extensions

See my [Example Extension project](https://github.com/Artikash/ExampleExtension) to see how to build an extension.

## Compiling

Before compiling *NextHooker*, you should get Visual Studio with CMake and ATL support, as well as Qt version 5.11<br>
You should then be able to simply open the folder in Visual Studio, and build. Run Build/NextHooker.exe

## Project Architecture

The host (see GUI/host folder) injects vnrhook.dll (created from the vnrhook folder) into the target process and connects to it via 2 pipe files.<br>
Host writes to hostPipe, vnrhook writes to hookPipe (duh?)<br>
vnrhook waits for the pipe to be connected, then injects a few instructions into any text outputting functions (e.g. TextOut, GetGlyphOutline) that cause their input to be sent through the pipe.<br>
Additional information about hooks is shared through a file view (a.k.a. section object) that is mapped to a reference to the Hook class.<br>
The text that the host receives through the pipe is then processed a little before being dispatched back to the GUI and displayed.

## Contributing

All contributions are appreciated! Please email (no, I'm not busy!) me at akashmozumdar@gmail.com if you have any questions about the codebase; I know it's messy and undercommented.<br>
You should use the standard process of making a pull request (fork, branch, commit changes, make PR from your branch to my master).
