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.

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