TeamViewer Permissions Hook V1

A proof of concept injectable C++ DLL, that uses naked inline hooking and direct memory modification to change TeamViewer permissions.

Features

As the Server - Enables extra menu item options on the right side pop-up menu. Most useful so far to enable the "switch sides" feature which is normally only active after you have already authenticated control with the client, and initiated a change of control/sides.
As the Client - Allows for control of mouse with disregard to servers current control settings and permissions.

Demo

As the Server

Client

Rundown

Utilizes signature/pattern scanning to dynamically locate key parts in the code at which the assembly registers hold pointers to interesting classes. Applies inline naked hooks a.k.a code caves, to hi-jack the pointers to use for modification via direct memory access to their reversed classes.
Inject and follow the steps

Requirements

Your favorite Manual Mapper, PE Loader, DLL Injector, inject into - "TeamViewer.exe"
This version was Built on Windows 10, for TeamViewer x86 Version 13.0.5058 - (Other versions of TeamViewer have not been tested but with more robust signatures it may work, linux not supported)

Disclaimer

Developed for educational purposes as a proof of concept for testing. I do not condone the or support the use of this software for unethical or illicit purposes. No responsibility is held or accepted for misuse.
