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.

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)
