Voyager - A Hyper-V Hacking Framework For Windows 10 x64 (AMD & Intel)

Voyager is a project designed to offer module injection and vmexit hooking for both AMD & Intel versions of Hyper-V. This project works on all versions of Windows 10-x64 (2004-1511). The project is currently split into two individual projects, one for Intel and another for AMD.

Voyager 1 - Intel

Voyager 1 contains all the code associated with the Intel part of this project. Since intel has vmread/vmwrite instructions all that is needed is a simple hook on the vmexit handler and interception can commence.

The payload solution contains a small CPUID interception example. I plan on expanding my examples to include EPT hooking and module injection/module shadowing. I also need to locate the self referencing pml4e in hyper-v's pml4 :|....

Voyager 2 - AMD

Voyager 2 contains all the code associated with the AMD part of this project. Since AMD has no vmread/vmwrite operation, only vmsave/vmload I had to locate the linear virtual address of the VMCB for every version of windows. GS register contains a pointer to a structure defined by MS, this structure contains alot of stuff. Deep in this structure is a linear virtual address to the current cores VMCB.

Currently the project is configured in such a way where you replace bootmgfw.efi on your EFI partition with Voyager. This requires secure boot to be disabled. If by any chance Voyager crashes/something goes wrong simply reboot your computer since bootmgfw.efi is restored instantly. If there are any issues please let me know! Ensure voyager is renamed to bootmgfw.efi and payload.dll are all in the same folder as launch.bat. Simply run launch.bat as admin. Once it has executed, your pc will reboot.

EFI Bundler

This code is used to bundled two EFI Modules together into a single module. The entry point of the second module is called first, then the first module's entry point is executed. Not sure what to do with this code so im just putting it in this repo for now. Might make another project for it.
