A kernel debugger that leverages hardware-assisted virtualization
HyperDbg is a kernel debugger that leverages hardware-assisted virtualization. More precisely, HyperDbg is based on a minimalistic hypervisor that is installed while the system runs. Compared to traditional kernel debuggers (e.g., WinDbg, SoftIce, Rasta R0 Debugger) HyperDbg is completely transparent to the kernel and can be used to debug kernel code without the need of serial (or USB) cables. For example, HyperDbg allows to single step the execution of the kernel, even when the kernel is executing exception and interrupt handlers. Compared to traditional virtual machine based debuggers (e.g., the VMware builtin debugger), HyperDbg does not require the kernel to be run as a guest of a virtual machine, although it is as powerful.
