design sketch:

VBScript finds hidden services by comparing the registry

Code (checksvr. VBS):

 

Copy codeThe code is as follows:


‘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
‘judge the service and use the array to compare. I don’t know if it will be faster?
  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

 

Using a dictionary is much faster:

 

Copy codeThe code is as follows:


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
