## What it is
A Windows research project that hooks system calls by loading Kaspersky's hypervisor driver (klhk.sys) and a custom kernel driver that subverts its syscall dispatch table. It demonstrates hijacking IA32_LSTAR-based syscall handling via a third-party hypervisor.

## Use cases
- hook system calls on Windows via a hypervisor
- research how Kaspersky's hypervisor dispatches syscalls
- build a custom syscall hooking driver
- study IA32_LSTAR and KiSystemCall64 hooking techniques
- experiment with VT-x based kernel hooking on bare metal

## When to choose
- you are researching hypervisor-based syscall hooking on Windows
- you want to experiment with Kaspersky's klhk.sys driver internals
- you need a working example of kernel-mode syscall interception

## When to avoid
- you need a production or stable hooking solution
- you run inside a VM or with Hyper-V/VBS enabled
- you cannot run on bare metal with hardware virtualization
- you need support for all Windows builds without driver version matching

## Facets
- artifact type: library
- maturity: experimental
- function: security, reverse-engineering, developer-tools
- domain: security, reverse-engineering, operating-systems, windows
- platform: windows, cpp
- tags: syscall-hooking, hypervisor, kernel-driver, rootkit-research, vt-x, klhk
