# KasperskyHook
Hook system calls on Windows by using Kaspersky's hypervisor
## How does it work?
Kaspersky utilizes its hypervisor when hardware virtualization is supported for additional protection. It hooks system calls by changing `IA32_LSTAR` to point to its own syscall handler (which is basically a copy of `KiSystemCall64`) so it dispatches system calls to its own handlers (while doing initialization, it builds its own dispatch table).
This project loads klhk.sys (Kaspersky's hypervisor module) and a custom driver which interfaces with it to subvert the system and hook system calls.
## Why did you write this?
While researching Kaspersky components, I thought it was an interesting idea to write a custom project that lets me hook system calls by using Kaspersky's hypervisor to take a closer look at what it is doing.
## Build steps - how to use it
* Download [Visual Studio 2019](https://visualstudio.microsoft.com/pt-br/downloads/), [WDK](https://docs.microsoft.com/en-us/windows-hardware/drivers/download-the-wdk), clone this repository and build the solution.
* Make sure `KasperskyHook.sys` and `KasperskyHookLoader.exe` are in the same folder. Copy `klhk.sys` to `\Windows\System32\drivers`
* Execute `KasperskyHookLoader.exe` and have fun :D
## Troubleshooting
If you followed the Build and Testing steps and `kaspersky::hvm_init()` returns `C00000A3` or `C000090B`, try following these steps:
* Make sure Virtualization (VT-x/AMD-v) is supported and enabled.
* Check if there are any other hypervisors conflicting with klhk (such as other AVs)
* Delete all KasperskyHook-related services, cleanup registry information and reboot
If it still doesn't work, consider using a newer version of klhk.sys. More information: https://github.com/iPower/KasperskyHook/issues/4
**MAKE SURE TO ENABLE TEST MODE TO TEST THIS PROJECT. IF YOU WISH TO USE IT OUTSIDE TEST MODE, USE YOUR CUSTOM DRIVER LOADER OR SIGN THE DRIVER.**
**NOTE: THIS ISN'T MEANT TO BE AN EASY-TO-PASTE-DETECTION-PROOF PROJECT. I JUST WROTE THIS FOR EDUCATIONAL PURPOSES SO I WON'T BE ADDING ANY HV-HARDENING OR ANTI-DETECTION CODE.**
