Vmware Hardened VM detection mitigation loader

For now, only Windows (vista~win10) x64 guests are supported.

It get vmware guest undetected by VMProtect 3.2, Safengine and Themida (anti-vm feature).

the VmLoader driver patches SystemFirmwareTable at runtime, it removes all detectable signatures like "VMware" "Virtual" "VMWARE".

Visual Studio 2015 / 2017 and Windows Driver Kit 10 are required.

Open VmLoader.sln with Visual Studio 2015 / 2017

Build VmLoader as x64/Release. (No x86 support for now)

Remember to test-sign "bin/vmloader.sys" if you want to load it in test-sign mode.

Do not install vmtools, it will ruin everything!

use TeamViewer / AnyDesk / mstsc / VNC viewer instead!

hypervisor.cpuid.v0 = "FALSE"
board-id.reflectHost = "TRUE"
hw.model.reflectHost = "TRUE"
serialNumber.reflectHost = "TRUE"
smbios.reflectHost = "TRUE"
SMBIOS.noOEMStrings = "TRUE"
isolation.tools.getPtrLocation.disable = "TRUE"
isolation.tools.setPtrLocation.disable = "TRUE"
isolation.tools.setVersion.disable = "TRUE"
isolation.tools.getVersion.disable = "TRUE"
monitor_control.disable_directexec = "TRUE"
monitor_control.disable_chksimd = "TRUE"
monitor_control.disable_ntreloc = "TRUE"
monitor_control.disable_selfmod = "TRUE"
monitor_control.disable_reloc = "TRUE"
monitor_control.disable_btinout = "TRUE"
monitor_control.disable_btmemspace = "TRUE"
monitor_control.disable_btpriv = "TRUE"

If you have a SCSI virtual disk at scsi0 slot (first slot) as your system drive, remember add

scsi0:0.productID = "Whatever you want"
scsi0:0.vendorID = "Whatever you want"

I use

scsi0:0.productID = "Tencent SSD"
scsi0:0.vendorID = "Tencent"

Modify guest's MAC address to whatever except below:

	TCHAR *szMac[][2] = {
		{ _T("\x00\x05\x69"), _T("00:05:69") }, // VMWare, Inc.
		{ _T("\x00\x0C\x29"), _T("00:0c:29") }, // VMWare, Inc.
		{ _T("\x00\x1C\x14"), _T("00:1C:14") }, // VMWare, Inc.
		{ _T("\x00\x50\x56"), _T("00:50:56") },	// VMWare, Inc.
	};

You could add

ethernet0.address = "Some random mac address"

into vmx file instead of modifying MAC address in vmware GUI

I use

ethernet0.address = "00:11:56:20:D2:E8"

If an error occurs when start service, use DbgView to capture kernel debug output. you can post an issue with DbgView output information and with your ntoskrnl.exe attached.

If no error occurs, then everything works fine.

vmware virtual graphic card information could be detected by querying DXGI interface, which could be modified by editing graphic driver files.
