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.
