Retrieving Password from Application Pool

I came across an undoc­u­ment­ed app the oth­er day. For a num­ber of rea­sons, we need­ed to restore the pass­word but it wasn’t doc­u­ment­ed any­where. Luck­i­ly, the ser­vice account was set­up in an app pool. In IIS 7.0 or 7.5, APPCMD can be used to recov­er the pass­word. In 6.0, adsutil.vbs can be used.

cscript.exe /nologo adsutil.vbs GET W3SVC/AppPools/AppPoolName/WAMUserPass

How­ev­er, I want­ed to write my own lit­tle script. Hav­ing a lit­tle tid­bit makes it easy to reuse lat­er for oth­er clients. For exam­ple, I could search AD for SPNs start­ing with “HTTP”, loop through each of their app pools and doc­u­ment the user­name and pass­words for all ser­vice accounts used in this fash­ion. So, here is the lit­tle tid­bit I threw togeth­er.

Option Explicit

Call GetAppPoolUserAndPass("localhost", "ApplicationPoolName")

Private Sub GetAppPoolUserAndPass (byVal strComputer, byVal strAppPool)
	Dim appPool
	On Error Resume Next
	Set appPool = GetObject("IIS://" & strComputer & "/w3svc/AppPools/" & strAppPool)
	If Err Then
		wscript.echo "Error connecting to " & chr(34) & strAppPool & chr(34) & " on " & strComputer
		wscript.echo strAppPool & vbTab & appPool.WAMUserName & vbTab & appPool.WAMUserPass
	End If
	On Error GoTo 0
End Sub

Here is an exam­ple of just what I men­tioned above. YMMV but this should dis­cov­er IIS box­es and report all the accounts used in their app pools. Note: Pools using built-in accounts will show up with blank pass­words; this is nor­mal; the pass­word isn’t actu­al­ly blank.

    Wscript.Echo "No SPNs Found matching HTTP*"
End If

Wscript.Echo "Computer Name" & vbTab & "AppPool Name" & vbTab & "User Name" & vbTab & "User Password"

The Power of Scripting: Finding Morto.A

Here I go on anoth­er vbScript tuto­r­i­al.  You might ask why I’m not doing this in pow­er­shell yet and it is sim­ple: I still run into 2003 and XP envi­ron­ments. Oh yeah, and this works. I don’t care what script­ing lan­guage I’m writ­ing in if it gets the job done; you shouldn’t either. My $0.02. If you want to down­load this script, click here: Morto.A Detec­tion Script.

A had to do a lit­tle cleanup on a net­work from the Morto.A worm.  The first thing I want­ed to do was find out how bad things were.  They were report­ing a DDOS across their LAN (most­ly 3389) and a lot of oth­er issues.  It as obvi­ous we were going to need to rebuild a few sys­tems but we want­ed to get a grasp out of what the dam­age was.  This were gen­er­al­ly work­ing: logons, shares, etc.

I’m not going to go over what we did on the fire­wall or local net­work but dis­cuss a quick script I threw togeth­er to scan the net­work for infect­ed sys­tems.  The trick was this net­work had mul­ti­ple domains and sev­er­al com­put­ers that weren’t even domain joined.

So, I put my automa­tion hat on and threw togeth­er a script I will out­line below.  I split this into sec­tions to help you see how you can use script­ing to piece togeth­er a com­pli­cat­ed job in sim­ple tasks.  It is pret­ty basic.  I start by defin­ing what I want to do:

Prob­lem state­ment: I need to check every com­put­er in each domain for infec­tion of the Morto.A worm.  I can split this into three dis­tinct steps:

  1. For Each Domain
  2. Get Each Com­put­er
  3. Check for Morto.A

For Each Domain

This is pret­ty sim­ple.  There are advanced tech­niques for find­ing all the domains in a for­est or read­ing from a text file or even a spread­sheet.  I like to keep it sim­ple and just cre­ate an array.

Dim arrDomains
arrDomains = Array("domain1.domain.local", "domain2.domain.local", "domain3.domain.local")
For Each Domain in arrDomains
	Call ComputersAll(Domain)

Get Each Computer

Now, I need to build the “Com­put­er­sAll” sub-rou­tine.  I call this in the domain script by pass­ing each domain in DNS for­mat.  I used DNS domains in my exam­ple on pur­pose (you could use the Dis­tin­guished­Name for­mat “dc=domain1,dc=domain,dc=local” but I pre­fer DNS names for this pur­pose).  By default, each com­put­er in that domain is going to reg­is­ter itself in DNS (assum­ing you set it up prop­er­ly).  I want to get the com­put­er name out of AD and append the dns domain name.  Once that is done, I want to use my “IsCon­nectible” script to check and make sure it is online.  If it pings, I should be able to car­ry out my busi­ness and find out if it is infect­ed.

The real mag­ic is in the lines: str­Base, strAt­trs and str­Fil­ter.  str­Base sets the search base to the domain you sent the sub-rou­tine.  It isn’t going to go out­side this domain for its search but it will search the whole domain due to its use of sub­tree.  The search a spe­cif­ic OU, you have to use the DN for­mat and that is out of scope of this arti­cle.  The strAt­trs is pret­ty straight for­ward.  This is an array of attrib­ut­es you want returned.  You could do DNS­Do­main­Name but some clients set this improp­er­ly.  It is safe to assume (in most cas­es) that the name and the domain name com­prise the DNS domain name.  The str­Fil­ter isn’t doing much but may look com­plex.  Basi­cal­ly, it is look­ing for com­put­ers in AD that aren’t dis­abled.

The oth­er things to pay atten­tion to is the line after

Do Until ADORecordSet.EOF

.  This checks first if the com­put­er is on the net­work through my “IsCon­nectible” script.  It pass­es the FQDN by append­ing “.” and the domain name to the name attribute from the query.

Const adUseClient = 3
Private Sub ComputersAll(byVal strDomain)
	Set adoCommand = CreateObject("ADODB.Command")
	Set adoConnection = CreateObject("ADODB.Connection")
	adoConnection.Provider = "ADsDSOObject"
	adoConnection.cursorLocation = adUseClient
	adoConnection.Open "Active Directory Provider"
	adoCommand.ActiveConnection = adoConnection

	strBase   =  ";"
	strFilter = "(&(objectClass=computer)(!userAccountControl:1.2.840.113556.1.4.803:=2));"
	strAttrs  = "name;"
	strScope  = "subtree"
	strQuery = strBase & strFilter & strAttrs & strScope
	adoCommand.CommandText = strQuery
	adoCommand.Properties("Page Size") = 5000
	adoCommand.Properties("Timeout") = 30
	adoCommand.Properties("Cache Results") = False

	Set adoRecordset = adoCommand.Execute

	If adoRecordset.RecordCount > 0 Then
		' wscript.echo "Computers for " & strDomain & ": " & adoRecordset.RecordCount
		' Loop through every single computer in the domain
		Do Until adoRecordset.EOF
			If IsConnectible(adoRecordset.Fields("name").Value & "." & strDomain) = "Online" Then Call DetectMorto(adoRecordset.Fields("name").Value & "." & strDomain)
	End If
End Sub

Check For Morto.A

This is the tricky part. I used sev­er­al sources and found two dis­tict char­ac­ter­isitcs of this work:

  1. C:windowssystem32sens32.dll
  2. HKLM­Sys­temW­PA
    1. Key: sr
    2. Val­ue: Sens

So, I need to check and see if a file and reg­istry key exists in order to detect if the machine is infect­ed.  There are a cou­ple of caveats with this: 1) when check­ing if a file exists, the default response is true on error, 2) you need local admin rights to query the c$ share, and 2) the reg­istry check relies on the remote reg­istry ser­vice.  To over­come these caveats, we put error check­ing in.  If an error occurs, it assumes a man­u­al check is need­ed.  We do this to err on the side of cau­tion.  Of course, on a large net­work, this isn’t desir­able.  Feel free to con­tact me if you need more advanced help.  Here is the sub-rou­tine I came up with to do all of the above.  It is mean and nasty and isn’t exact­ly the kind of finesse I pre­fer but, it works…

First, I try writ­ing a temp file (and delet­ing it if it suc­ceeds). If that works, I should be able to detect if the file exists and con­nect to the remote reg­istry. How­ev­er, per­haps you are an admin that is para­noid and dis­ables the remote reg­istry ser­vice. Well, it will still detect an error and tell you to check man­u­al­ly. Of course, if you don’t have admin rights, it will also tell you to check remote­ly.

Private Sub DetectMorto(byVal strComputer)
	' Detects morto via several methods...
	Dim blnInfected : blnInfected = False
	' Requires admin rights to properly detect. Check for rights
	Dim objFSO : Set objFSO = CreateObject("Scripting.FileSystemObject")
	On Error Resume Next
	Dim TempFile : Set TempFile = objFSO.CreateTextFile("\" & strComputer & "c$WINDOWStempfile.deleteme", True)
	TempFile.WriteLine("This is a test.")
	Set TempFile = Nothing
	objFSO.DeleteFile("\" & strComputer & "c$WINDOWStempfile.deleteme")	
	If Err Then bnlInfected = "Error"
	On Error GoTo 0
	' Check for registry key placed by Morto...
	Dim strKeyPath, strEntryName, objReg, strValue
	strKeyPath = "SYSTEMWPA"
	strEntryName = "sr"
	On Error Resume Next
	Set objReg = GetObject("winmgmts:{impersonationLevel=impersonate}!\" & strComputer & "rootdefault:StdRegProv")
	objReg.GetStringValue HKEY_LOCAL_COMPUTER, strKeyPath, strEntryName, strValue

	If Err Then blnInfected = "Error"
	If strValue = "Sens" Then blnInfected = True
	' Check for file indicating morto infection
	Dim strMortoSens32
	strMortoSens32 = "\" & strComputer & "c$WINDOWSsystem32Sens32.dll"
	If objFSO.FileExists(strMortoSens32) Then blnInfected = True
	' If the Infected flag is set, it is infected...
	If blnInfected = True Then
		wscript.echo "*******MORTO INFECTION: " & strComputer
	ElseIf blnInfected = "Error" Then
		wscript.echo "Error (Check Manually): " & strComputer
		wscript.echo "Clean: " & strComputer
	End If
End Sub


So, I have tak­en sev­er­al scripts and thrown them togeth­er to find a solu­tion. I can reuse this for any­thing. Per­haps I want to use vbscript to find com­put­ers with a cer­tain file on their hard dri­ve. I can reuse this by just tweak­ing the Mor­to sub-rou­tine.

IsConnectible: My vbScript Ping Method

When­ev­er I am doing large sweeps of the net­work that require con­nect­ing to a large num­ber of work­sta­tions (e.g. file copy, wmi query, etc.), I pre­fer to check to see if I can even see the sys­tem. This avoids wait­ing for (WMI) time­outs and also aids in trou­bleshoot­ing fail­ures. If the file copy failed, why? Well, if I can’t ping it or it can’t be resolved, I would like to know right away and move on to the next host.

Of course, there are a cou­ple down­sides to this method. It does add over­head to the script because it too has a time­out. How­ev­er, depend­ing on the pur­pose of the script, this may be accept­able for the flex­i­bil­i­ty you gain. The oth­er caveat is that the sys­tems you run this against must allow ICMP on their local fire­wall or the script will just ignore them and move on to the next host.

There are sev­er­al meth­ods for ping­ing hosts but I’ve found this to be the most reli­able since it works against any sys­tem that allows ICMP, even Lin­ux or Macs. This is adapt­ed from Richard Mueller’s ping script. This method will return three pos­si­ble val­ues: “Online”, “No Ping Reply”, or “No DNS/WINS Entry”. You can also tweak the ping com­mand options to your lik­ing.

Here is an exam­ple of how to call the func­tion:

Dim computers(2), computer, pingable
computers(0) = "pc-100.domain.local"
computers(1) = "pc-200.domain.local"
comptuers(2) = "pc-300.domain.local"
For Each computer In computers
	Select Case IsConnectible(computer)
		Case "Online"
			wscript.echo computer & " is online"
		Case "No Ping Reply"
			wscript.echo computer & " is offline or firewall blocks ICMP"
		Case "No DNS/WINS Entry"
			wscript.echo computer & " cannot be found in DNS/WINS"
		Case "Host Unreachable"
			wscript.echo computer & " is unreachable"
	End Select

Here is the func­tion:

Private Function IsConnectible(ByVal strComputer)
	' Uses ping.exe to check if computer is online and connectible.
	' Adapted from
	Dim objShell, objExecObject, strText
	Set objShell = CreateObject("Wscript.Shell")
	' use ping /? to find additional values for ping command; see -n and -w
	Set objExecObject = objShell.Exec("%comspec% /c ping -n 2 -w 750 " & strComputer)
	Do While Not objExecObject.StdOut.AtEndOfStream
		strText = strText & objExecObject.StdOut.ReadLine()
	If InStr(strText,"could not find host") > 0 Then
		IsConnectible = "No DNS/WINS Entry"
	ElseIf (InStr(strText,"Reply from ") > 0) And (InStr(strText,": bytes=") > 0) Then
		IsConnectible = "Online"
	ElseIf InStr(strText,"Destination host unreachable") > 0 Then
		IsConnectible = "Host Unreachable"		
		IsConnectible = "No Ping Reply"
	End If
End Function

vbScript: Adding and Removing a Domain Group to a Local Group

Yes, I still use vbscript. Some­day, I’ll get to work in an envi­ron­ment where every­thing is upgrad­ed. Until then, I have to rely on the tried and true vbscript.

One of the most com­mon uses of a Group Pol­i­cy start­up script is for adding users to the local admin group. Just google it and you will find hun­dreds of scripts doing just that, batch files, posh, vbscript, perl, etc. I wrote the script below because I want­ed the flex­i­bil­i­ty to reuse this script at any client and for any group (not just Admin­is­tra­tors but Remote Desk­top Users or Pow­er Users).

The con­fig sec­tion takes three argue­ments: Action, str­Local­Group, str­Do­main­Group.

  • Action: Can be either “Add” or “Remove”. It will either add the domain group to the local group or remove it.
  • str­Local­Group: The name of the local group (e.g. Admin­is­tra­tors, Pow­er Users, etc.). I test­ed w/ all the stan­dard built-in groups.
  • str­Do­main­Group: The name of the domain group to add to the local group. Note: The work­sta­tion has to be a mem­ber of the same domain the group resides in.

vbScript: Tweaking Power Settings (disabling hibernate and standby)

As is often the case in IT, when you need to push out that soft­ware pack­age or migrate that com­put­er to a new domain, it isn’t on the net­work.  This has come up sev­er­al times in the past year and I want­ed to share my solu­tion.  Now, this isn’t the “green­est” solu­tion because this will ensure your clients nev­er go into a pow­er sav­ing mode.  How­ev­er, it can be a tem­po­rary fix for a project.  It can also be adapt­ed to force stand­by or hiber­nate at spe­cif­ic thresh­olds.

While Win­dows 7 and Vista make this task sim­ple, XP is still a real­i­ty in most enter­pris­es and SMB’s and there­fore, must be tak­en into account.  The script below does just that.  Some addi­tion­al exam­ples can be found at the US Government’s Ener­gy Star web­site.

Note: Copy­ing the script from the web­page may cause for­mat­ting issues.  You can down­load the script here: tweak-power-settings.vbs

vbScript: Quickly determine architecture

I’ve been using a rou­tine to deter­mine 64-bit v 32-bit work­sta­tions for some time check­ing the reg­istry for the PROCESSOR_ARCHITECTURE in the HKLM­SYS­TEM­Cur­rent­Con­trolSet­Con­trolSes­sion Man­agerEn­vi­ron­ment path. How­ev­er, this was prov­ing to be error prone. So, I just gave up that method alto­geth­er since all Win­dows x64 edi­tions have a “%SystemDrive%Program Files (x86)” direc­to­ry. This makes it just a quick and easy call the folderex­ists method of the filesys­te­mob­ject.

The only down­side is that can’t be used remote­ly but since most of my scripts are used in local poli­cies, this shouldn’t be an issue.


Private Function is64bit()
	Dim filesys : Set filesys = CreateObject("Scripting.FileSystemObject")
	Dim bln64bit : bln64bit = False
	If filesys.FolderExists("C:Program Files (x86)") then bln64bit = True

Installing Java via Script and Group Policy

Due to some soft­ware require­ments, there was a need to get JRE 1.5.0_09 rolled out across our enter­prise. The require­ments were pret­ty straight for­ward:

  • Only install on client oper­at­ing sys­tems (Win­dows 2000, Win­dows XP, Win­dows Vista and Win­dows 7)
  • Detect the ver­sions of Java installed. If 1.5.0_09 is installed, exit.  If 1.5.0_08 or less was installed, install this ver­sion.  If it has a new­er ver­sion, do noth­ing.

The best way of deter­min­ing the Java ver­sions is to look in %pro­gram files%.  On 64-bit machines, this is “C:program files (x86)Java”.  On 32-bit, this is “C:program files­Ja­va”.  The script accounts for this.

I want­ed to post this because sev­er­al of the func­tions used are very use­ful.  The share host­ing the jre run­time needs to have wide open read-only access so the Local Sys­tem account can access share (Domain Com­put­ers).  This script can then be applied to machine accounts in group pol­i­cy as a start­up script.  If you want to test this, just com­ment out line 111.

The prob­lem I found was the log was so full of failed logon attempts it was dif­fi­cult to fil­ter out what I was look­ing for. In a twelve hour peri­od, there were thou­sands of 529 events in the secu­ri­ty log. Now, I know this is noth­ing new, but I found a few pat­terns. I man­u­al­ly export­ed the log to a CSV, parsed out all the source ip address­es and opened it up in Excel. What I found was that 98.7% of failed logon attempts were made by just four dif­fer­ent ip address­es.  (I rec­om­mend using MaxMind’s GeoIP Address Loca­tor for help in deter­min­ing where the source address­es are locat­ed.)
