Solution Projects

Common

This project is a static library that houses common functions of all other projects. For example, all projects need to access config file and logging utilites, so they are defined in this module.

Injector

This project is a simple DLL injector executable. The injector can be used as a command line utility that accepts 2 arguments: ID of the process which should be injected and DLL to inject.

Integration

This project is a dynamic library that pretends to be version.dll. Nothing much going on here except for loading of the unlocker module.

‍ Integration Wizard

This project is a trivial GUI utility that automatically installs the integration files and copies the original ones. The GUI is using Task Dialog available in Windows API.

Unlocker

This project is a dynamic library which performs the main function of Koalageddon - DLC unlocking. It monitors DRM DLLs using undocumented WinAPI functions and suspends new processes before injection using undocumented functions as well. Once target DLLs have been identified, appropriate functions are hooked using the great PolyHook 2 library. A total of 4 hooking techniques are used in this project.

Dependencies

The solution uses a number of third party dependencies, which are available via vcpkg. Projects in the solution are configured to use static libraries instead of dynamic. If you wish to build the solution yourself, you would need to install the following libraries:

• Boost preprocessor
• C++ Requests
• nlohmann JSON
• PolyHook 2.0
• spdlog
• TinyXML-2
• WinReg

The solution includes the install_vcpkg_dependencies.bat script, which installs all of the above-mentioned dependencies with a single command.

You can verify installations via vcpkg list
