我是靠谱客的博主殷勤可乐，最近开发中收集的这篇文章主要介绍VBScript之通过对比注册表查找隐藏的服务，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

效果图：

代码（checksvr.vbs）：

复制代码代码如下:

'On Error Resume Next

Const HKEY_LOCAL_MACHINE = &H80000002

Set oReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\default:StdRegProv")

strKeyPath = "SYSTEM\CurrentControlSet\Services"
oReg.EnumKey HKEY_LOCAL_MACHINE, strKeyPath, arrSubKeys

Wscript.Echo "Checking, please wait ..."
Wscript.Echo ""

For Each subkey In arrSubKeys
oReg.GetStringValue HKEY_LOCAL_MACHINE, strKeyPath & "\\" & subkey, "ObjectName", strValue

If Not (strValue = "") Then
  '判断服务, 利用数组来比较不知道会不会快些？
  If Not (CheckSvr(subkey)) Then
   Wscript.Echo subkey & FormatOutTab(subkey) & strValue & FormatOutTab(strValue) & "[ Hidden ]"
  Else
   Wscript.Echo subkey & FormatOutTab(subkey) & strValue & FormatOutTab(strValue) & "[   OK   ]"
  End If

End If
Next
Wscript.Echo ""
Wscript.Echo "All done."
Wscript.Quit (0)

Function CheckSvr(strName)
Set oWMI = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\.\root\cimv2")
Set cService = oWMI.ExecQuery("Select * from Win32_Service WHERE Name='" & strName & "'")
If (cService.count <> 0) Then
CheckSvr = True
Else
CheckSvr = False
End If
End Function

Function FormatOutTab(strName)
strLen = Len(strName)
Select Case True
  Case strLen < 8
   FormatOutTab = vbTab & vbTab & vbTab & vbTab & vbTab

  Case strLen < 16
   FormatOutTab = vbTab & vbTab & vbTab & vbTab

  Case strLen < 24
   FormatOutTab = vbTab & vbTab & vbTab

  Case strLen < 32
   FormatOutTab = vbTab & vbTab

  Case strLen < 40
   FormatOutTab = vbTab

  Case Else
   FormatOutTab = vbTab
  End Select
End Function

利用字典，速度要快很多：

复制代码代码如下:

Dim oDic, oReg, oWmi, arrServices
Const HKEY_LOCAL_MACHINE = &H80000002

Wscript.Echo "[*] Checking, please wait ..."
Wscript.Echo ""

Set oDic = CreateObject("Scripting.Dictionary")

Set oWmi = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\.\root\cimv2")
Set arrServices = oWmi.ExecQuery("Select * from Win32_Service")
For Each strService In arrServices
oDic.Add strService.Name, strService.Name
Next

Set oReg = GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\default:StdRegProv")
strKeyPath = "SYSTEM\CurrentControlSet\Services"
oReg.EnumKey HKEY_LOCAL_MACHINE, strKeyPath, arrSubKeys

For Each subkey In arrSubKeys
oReg.GetStringValue HKEY_LOCAL_MACHINE, strKeyPath & "\\" & subkey, "ObjectName", strValue
If Not (strValue = "") Then
  If oDic.Exists(subkey) Then
   Wscript.Echo subkey & FormatOutTab(subkey) & strValue & FormatOutTab(strValue) & "[   OK   ]"
  Else
   Wscript.Echo subkey & FormatOutTab(subkey) & strValue & FormatOutTab(strValue) & "[ Hidden ]"
  End If
End If
Next

oDic.RemoveAll

Wscript.Echo ""
Wscript.Echo "[*] All done."
Wscript.Quit (0)

Function FormatOutTab(strName)
strLen = Len(strName)
Select Case True
  Case strLen < 8
   FormatOutTab = vbTab & vbTab & vbTab & vbTab

  Case strLen < 16
   FormatOutTab = vbTab & vbTab & vbTab

  Case strLen < 24
   FormatOutTab = vbTab & vbTab

Case strLen < 32
FormatOutTab = vbTab

  Case Else
   FormatOutTab = vbTab
  End Select
End Function
