I'm on VMWare, Windows 10 22H2, other hypervisors off, HVCI off, antivirus fully unistalled

RU:
Привет,если я смаплю KasperskyHookDriver.sys тогда у меня появляется BSOD с ошибкой: PAGE_FAULT_IN_NON_PAGED_AREA.Как это можно пофиксить?
It seems that this method does not support the latest klhk.sys
The January 19, 2024 version will have a blue screen

Hello,
I would like to ask about how I should add another function to be hooked.
And also, I want to know the process that made this system call. Is it possible?
I want to use that project to hook API calls done by a process and then send those called APIs to an engine running in user mode to analyze them and decide whether the process is malicious or not. (it's a part that I'm going to use in my graduation project).
Thanks.
im trying to use kaspersky's cpu handler for code injection by hooking it and as i know this handler called in context of process that made execution of cpuid instruction but when im calling ZwAllocateVirtualMemory im getting HYPERVISOR_ERROR bsod
is it even possible to work with process memory in cpuid handler?
thats what im hooking in their driver: https://i.imgur.com/4NfM8kZ.png
ida sig to both handlers: 48 89 5C 24 ? 57 48 83 EC 20 4C 8B 81
VMP EXEfile BOOM~~~
need set CPUID callback
i tried using the project with virtualization enabled on my vm / main pc
the kaspersky hypervisor is loaded i checked the service.
but when calling return NT_SUCCESS( set_hvm_event() );
this returns false because set_hvm_event() doesnt return STATUS SUCCESS it returns: C00000A3 (STATUS_DEVICE_NOT_READY) sometimes returns C000090B.
bool kaspersky::hvm_init()
{
if ( !provider || !set_hvm_event )
return false;
*provider = 4;
auto ret = set_hvm_event();
log("%p\n", ret);
return NT_SUCCESS(ret);
}
[ KasperskyHook ] 00000000C00000A3
edit: driver is also signed i am using a cert.
https://guidedhacking.com/threads/kasperskyhook-hook-windows-system-calls.16030/post-98821
same error as this guy ^
except i have virtualization enabled
is it possible to hide kernel memory modifications with kaspersky hypervisor? if its possible can you give me hints where to dig in their driver?
VM: Install Kaspersky (get new driver)
code:
fix ssdt_service_count (change sig) (old sig boken, i fixed。 got 3 version klhk.sys , only here no change .)
presult = utils::find_pattern_km(L"klhk.sys", ".text", "\x83\xE1\x01\x75\x27", "xxxxx"); if (!presult) return false; presult = presult + 0xE;
test , and again return C000090B (include VM return C000090B)
...emmmm any update or etc?
