VMwareHardenedLoader

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).

What it does

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

Build

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.

Installation

Warning

Do not install vmtools, it will ruin everything!

Use TeamViewer / AnyDesk / mstsc / VNC viewer instead!

1st Step: Add following settings into .vmx

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"
monitor_control.disable_btseg = "TRUE"
monitor_control.restrict_backdoor = "TRUE"

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

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

I use

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

2nd Step: Modify MAC address

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"

3rd Step: Run install.bat in vm guest as Administrator Priviledge

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.
