如何检测（.NET 或 Win32）我的应用程序是否在虚拟机中运行？
这就是我用的：
using (var searcher = new System.Management.ManagementObjectSearcher("Select * from Win32_ComputerSystem"))
{
using (var items = searcher.Get())
{
foreach (var item in items)
{
string manufacturer = item["Manufacturer"].ToString().ToLower();
if ((manufacturer == "microsoft corporation" && item["Model"].ToString().ToUpperInvariant().Contains("VIRTUAL"))
|| manufacturer.Contains("vmware")
|| item["Model"].ToString() == "VirtualBox")
{
return true;
}
}
}
}
return false;
编辑 2014-12-02：更新了代码，使其不再将 Microsoft Surface Pro 检测为虚拟机。感谢 Erik Funkenbusch 指出了这一点。
编辑 2017-06-29：更新了代码，以便它还检查
HypervisorPresent编辑 2018-02-05：删除了对
HypervisorPresent根据Virtual PC Guy的博文“检测微软虚拟机”，您可以使用WMI来检查主板的制造商。在 PowerShell 中：
(gwmi Win32_BaseBoard).Manufacturer -eq "Microsoft Corporation"
此 C 函数将检测 VM Guest OS： （在Windows上测试，使用Visual Studio编译）
#include <intrin.h>
bool isGuestOSVM()
{
unsigned int cpuInfo[4];
__cpuid((int*)cpuInfo,1);
return ((cpuInfo[2] >> 31) & 1) == 1;
}
Jay Abuzi 在 powershell 中展示了解决方案。这与 C# 函数相同：
/// <summary>
/// Detect if this OS runs in a virtual machine
///
/// http://blogs.msdn.com/b/virtual_pc_guy/archive/2005/10/27/484479.aspx
///
/// Microsoft themselves say you can see that by looking at the motherboard via wmi
/// </summary>
/// <returns>false</returns> if it runs on a fysical machine
public bool DetectVirtualMachine()
{
bool result = false;
const string MICROSOFTCORPORATION ="microsoft corporation";
try
{
ManagementObjectSearcher searcher =
new ManagementObjectSearcher("root\\CIMV2","SELECT * FROM Win32_BaseBoard");
foreach (ManagementObject queryObj in searcher.Get())
{
result = queryObj["Manufacturer"].ToString().ToLower() == MICROSOFTCORPORATION.ToLower();
}
return result;
}
catch (ManagementException ex)
{
return result;
}
}
记住你不应该只检查流行的虚拟机型号，来自wmi的制造商名称，你还应该检查现实和虚拟化之间的差异。
VM没有太多功能。
1) 检查CPU温度信息是否可用
wmic /namespace:\\root\WMI path MSAcpi_ThermalZoneTemperature get CurrentTemperature
//On Real PC
//CurrentTemperature
//3147
//On VM
//Node - Admin
//Error:
//Description not supported
在 vmware、virtualbox、windows 服务器、app.any.run 沙箱上测试。
2) Win32_PortConnector
Get-WmiObject Win32_PortConnector
//On Vm it is null
//On real pc it looks something like that
Tag : Port Connector 0
ConnectorType : {23, 3}
SerialNumber :
ExternalReferenceDesignator :
PortType : 2
public static bool isVirtualMachine()
{
const string MICROSOFTCORPORATION = "microsoft corporation";
const string VMWARE = "vmware";
foreach (var item in new ManagementObjectSearcher("Select * from Win32_ComputerSystem").Get())
{
string manufacturer = item["Manufacturer"].ToString().ToLower();
// Check the Manufacturer (eg: vmware, inc)
if (manufacturer.Contains(MICROSOFTCORPORATION) || manufacturer.Contains(VMWARE))
{
return true;
}
// Also, check the model (eg: VMware Virtual Platform)
if (item["Model"] != null)
{
string model = item["Model"].ToString().ToLower();
if (model.Contains(MICROSOFTCORPORATION) || model.Contains(VMWARE))
{
return true;
}
}
}
return false;
}
对于较低级别的测试，我建议查看 ScoopyNG [1]。它是已知的低级、运行良好的虚拟机检测方法的集合，尽管有点过时。
如果您确实想依赖其他东西，例如安装的工具（VM* Additions），那么这些更容易“伪造”。
这篇 [2] 博客文章也有一个非常好的概述，从低级 asm 内容开始，检查特定的 DLL、文件路径和注册表项。
