What did they take when they left? Part 3 - Where did it go and what did they take?

Howdy Reader,

In the prior posts in this series we've talked about how to determine if our suspect burned a CD and then what programs he ran before he left. In this post we will discuss ways our suspect could have taken out of the system and how we can find out what they took. There are several options available to someone who wants to take data depending on the environment they are in. They could burn a cd (which we talked about before), send out an email via their companies servers, send out an email via a webmail service, copy the data to a external drive, copy data to another network location or upload data to a web based file hosting service are the most common. Any combination of these methods can be used so we have two challenges:

We need to determine what method or methods they used to take data from the system
We need to determine what files they took using these methods

Method 1 – Email via corporate servers

How did they take data from the system

How we are able to recreate activities will depend on the email system they have in place. Typically a suspect using this method will be emailing files and forwarding messages to their personal account. The sophistication of the suspect is pretty low in this method but occasionally even these suspects will delete these messages. Every email system has its own particular quirks for the recovery and analysis of messages, enough so that we will have separate posts to deal with each one at a later date. In most cases if a user has deleted the email messages we have three sources of recovery:

Recovery of deleted messages from the local system

When an email is sent from a suspect's system it is typically saved in the local and possible the server side 'sent' box. How we recover the message depends on how much time has passed since the user deleted the message, what other activity has occurred on the system since that time and whether or not the user purposefully attempted to push the email out of the local email archive.

i. Messages recovered from the application database structure

Most email systems have an accompanying client side application (groupwise, outlook, notes) that store the emails they receive into a database like structure. Typically when these emails are deleted they remain within the database like structure until they are flushed out (such as using the outlook compact and repair function). Until that occurs then most of the major commercially available forensic tools (Paraben's email examiner, Encase Forensic, Forensic Toolkit) can recover these deleted messages if they support the file format. If you are looking for a free option you might try the steps outlined here but that could become quite burdensome if you have a large number of messages to recover.
ii. Messages recovered from the unallocated space
Depending on the email client used the data will either be in plain text in the unallocated space for easy carving or it may be stored in some binary format such as the case with deleted messages from most outlook pst's. Outlook pst's support a data encoding format known as outlook compressible encryption. When this data is pushed out of the pst structure either over time or through the operation of a compact and repair the message will then exist in the unallocated space but be encoded in OCE. The only tool I know of currently that can search for OCE data in the unallocated space is encase. However the temporary files made by Microsoft Word, which has been the default editor for emails inside of Outlook since at least 2003, are recoverable as plain or Unicode text in the unallocated space.
Recovery of deleted messages from the live server

Most email servers don't flush out emails from their database when the user deletes them. If you or your IT contact has administrative access to the email server you can ask them to recover recently deleted messages from the live server. In exchange there is what has been called a 'dumpster' functionality that will retain emails for a definable set of days (default of 14 I believe). In groupwise you can recover deleted messages using tools like network email examiner or the salvage utility. In lotus notes you could either check to see if the 'soft delete' option was set and for how long it will retain messages or again use commercial tools. There are not many (any?) open source or free tools for dealing with enterprise email server solutions.

If the email server has flushed out the message recovering the message from the unallocated space becomes more difficult since I don't know the encoding of the message. If you are dealing with a sendmail/imail server like Iplanet you can recover the messages in the unallocated space through regex searches for headers.
Recovery of deleted messages from backup

When all else fails you can go to backup, usually tape. Restore the email database for the relevant time intervals to hopefully capture the email it was not purged the same day it was deleted, not very typical. You can restore the tape with either the native software (netbackup, backupexec, arcserve, etc…) or with software that supports your tape format (Ontrack Powercontrols, Quest Recovery Manger for Exchange). Then you will need to access the email database either with the native email server in a recovery environment or with a tool that supports reading the database directly (network email examiner, Ontrack Powercontrols, Quest Recovery Manger for Exchange). Once you've done this you can see if the emails you are looking for exist. This is a very detailed topic on the variances of backup software for the forensic examiner and data available, I plan to make separate posts about each of the major backup formats and tape examination techniques.
What did they take

Now that we have the email messages we can see what was forwarded and attached to those messages to make a list of those files, email addresses and subject matters. In my job I have no knowledge of internal matters so I have to hand over this data to counsel so they can determine what that was sent to themselves contained relevant data.

Method 2 – Email via webmail

How did they take data from the system

The first step I would perform is examining the internet history of the user. If they did not clear out their internet history then you can look through it for webmail websites they have been visiting. The majority of webmail services are either free or in the case of a hosted website they own will be using a free webmail package (like squirrel mail). We can use these sites to get unique keywords they display in either the html source of the page or in the rendered page itself to identify specific pages of interest.

The nature of how we send and receive data to websites dictates what is and is not recoverable. We can recover pages they have viewed, such as the contents of a mailbox/folder . We can see messages received the form to write an email but not the email they wrote. So we can look for the most recent views of their inbox for emails they have sent to themselves with files attached. Many people have said that gmail no longer leaves cached emails for us to recover. This is not in fact true, the move to the ajax model means we no longer have a separate cached page for every email viewed, instead we have to look at the virtual memory (pagefile.sys in windows, the swap partition in unix based systems) to find these email remnants.
What did they take

Most webmail sites will separately make a pop up or page for attaching files and giving notification of successfully attached files. This is good for us as we can recover each notification page and make a list of what files they sent themselves. In addition some suspects are nice enough to open each email they forwarded to themselves to just make sure they got their files.

There are three more methods to detail, but I don't want to wait another day to get this up. To be continued in part 4.

What did they take when they left? Part 1 - Detecting CD Burning

Hello Reader,

In Part 1 we discussed how to determine if a CD was burned. Knowing what application it was burned with and what other tools they ran before they left is also important.

User Assist

One way to determine this is with the user assist registry keys. Over the years since the user assist registry keys were first discovered (they were included in our windows analysis chapter in 2005) many people have realized the impact it can have on their case. The User Assistance functionality has existed since Windows 2000 and is a registry key divided into two parts that keeps track of recently used programs and files for the start menu.

The user assist registry key exists in each user's ntuser.dat under the key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\UserAssist

Of which there are multiple keys depending on the version of windows you are examining, two for windows 2000, xp, 2003 and three for windows vista, server 2008, under which you will find a count key that contains the actual data we are looking for. Entries are encoded in rot13 and if you are not using one the tools listed in this blog you will need to decode them yourself to read the entries.

There are multiple tools that support the user assist registry keys for analysis (Accessdata's registry viewer and Didier Stevens tool for instance) that will quickly allow you to see:

What program or file was accessed
How many times the program or file has been accessed through windows explorer
The last time the program or file was accessed through windows explorer

As a simple example, I use Microsoft Office a lot. In fact I write my blog posts in it as it can directly post them to blogger (hopefully catching all my typos). So a decoded user assist entry for Office in my registry looks like this:

"{75048700-EF1F-11D0-9888-006097DEACF9}","20","UEME_RUNPATH:C:\Program Files\Microsoft Office\Office12\WINWORD.EXE","","54","37","3/22/2009 9:25:59 PM"

This entry was found in:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\UserAssist\{75048700-EF1F-11D0-9888-006097DEACF9}\Count

Decoding the entry section by section we see:

{75048700-EF1F-11D0-9888-006097DEACF9} - the registry key under user assist that this belongs to, data appears to be grouped into categories based on these id's.
20 – The index number this number increments as entries are added to this key. In this case this is the 20^th entry logged. If you have a program executed multiple times, such as my Word 2007 program, sorting by the index number will give you an idea of when it was first executed.
UEME_RUNPATH:C:\Program Files\Microsoft Office\Office12\WINWORD.EXE – This is two pieces of info combined into one:
1. UEME_RUNPATH – This is the prefix for all entries that will give you a full path to the program or file being accessed
2. C:\Program Files\Microsoft Office\Office12\WINWORD.EXE – this is the full path to the program or file executed
54 – This is the session, its use is still unknown
37 – This is the number of times the program has been executed
3/22/2009 9:25:59 PM – This is the last time the key was updated and should be the last time it was executed

Going through the user assist then allows us to find out what programs where being executed around the time that for instance a CD was burned. Sorting the entries for that time we can see what was being executed around that time. If there is no corresponding entry you may want to look at the restore points for backups of the ntuser.dat close to time of the burn to find the program executed.

If the user assist keys is missing two things could have occurred

The user disabled them, there will be a registry key created showing this if true.
The user has deleted them, this can be an indication of some type of 'cleaning' tool being run such as Crap Cleaner.

Now the user assist registry keys are not the only place to look for what programs have been executed. We don't want to rely solely on access times as they change so easily and don't prove that a program was actually executed. We want to focus on artifacts created because of an execution of which there are two other well documented sets of artifacts that show the actual execution of a program.

Shortcut/Lnk Files

Stored in several locations depending on its function LNK files so named because of the extension '.LNK' that is given to them. We will discuss LNK files in more detail in the next post as they are an extreme wealth of information but for the purposes of this post it can suffice to say that we can use LNK files to determine if a program was executed through it.

The start menu for each user stored from windows 2000 and on is under the user's profile directory (\documents and settings\<user>\start menu in xp and \users\<user>\start menu in vista and 2008) contains a LNK file for each of the files listed in the user's start menu when the click the start button. So each time a user loads a program through it the modified date of the LNK file will change to reflect it. This also applies to any other instance of the lnk file such as in the quick launch bar or on the desktop.

So for instance my Office 2007 LNK file in the start menu shows a created time of 11/24/2008 which is when I installed office 2007 on this computer. The modification date is 3/22/09 9:25pm which is the last time I used the LNK file to load up office 2007. You can see that the prefetch reference below says 9:26pm, it takes a couple second between the time I clicked the LNK and when the prefetch file gets created.

Prefetch Files

Stored in the \Windows\Prefetch directory there is one .pf file for each of a max of 128 programs and the last modified time is updated each time the program is executed. The Forensic Wiki has a nice write up on prefetch files. There are several tools out there for parsing prefect files, one that is free is part of the Windows File Analyzer program. If I were to analyze the prefetch file for Office 2007 I would see the following:

File name: WINWORD.EXE-6AC9169C.pf

Last loaded: 3/22/09 and 9:26PM

This is when I started writing this blog post, it's been a couple days of research catching up on old topics to see what people have figured out.

So the prefetch file is a third correlation point we can use to determine if and when a program has been executed.

Conclusion

So we now have three separate sources on a typical Windows system that we can use to determine what programs had been executed (the first and last times), when and how many times they have been executed. These are not the only places we can look for this information but they are three of the most reliable due to the nature of their creation and use. If you find that all of this data is missing then it becomes almost certain that either

The system is being reimaged each time it reboots/logs in (some public access terminals do this)
A cleaning/wiping tool has been run

I plan to make a post on how to determine what a user has wiped after this series but if a cleaning tool has not been run one or all of these sources will allow you to state for a fact what program was executed to:

Run a backup program (such as the ones that are packaged with some external hard drives like retrospect)
Burn a CD
Run an ftp program
Access some kind of archiving or copy tool

Which will then lead to the next question and our next post in the series : Part 3 - Where did it go and what did they take?

Blackberry Server Log Analysis by David Cowen - Hacking Exposed Computer Forensics Blog

Hello Reader,

To the end user the blackberry server is what their blackberries get their email from. But there are multiple methods of communication a blackberry is capable of relaying, logging and recovering by an informed investigator.

Email
SMS
Blackberry Messenger
PIN Messaging
Phone Call Log

The blackberry server will create the following type of logs in total:

ALRT - BES Alert
BBIM - BlackBerry Instant Messenger (4.1)
BBUA - BlackBerry User Administration Service (BRK)
CBCK - Backup Connector
CEXC - Exchange PIM Connector
CMNG - Management Connector
CTRL - BlackBerry Controller
DISP - BlackBerry Dispatcher
MAGT - BlackBerry Mailbox Agent (aka BlackBerry Messaging Agent)
MDAT - Mobile Data Services
MDSS - MDS Services (4.1)
MDSS-DISCOVERY - MDS Services (4.1)
POLC - Policy Service
ROUT - Router
SYNC - BlackBerry SyncServer
PhoneCallLog (4.1)
PINLog (4.1)
SMSLog (4.1)

(Thanks Wikipedia http://en.wikipedia.org/wiki/BlackBerry_Enterprise_Server)

Email – The blackberry server logs will store when a device connects to the server to pull email and delivers mail and other messages. When you are dealing with a time sensitive issue of did a message get received/sent/deleted from a blackberry these logs may be your best source of evidence if a enough time has passed to let the message be deleted from the blackberry device itself before imaging. Regarding imaging blackberry devices I personally use Paraben's device seizure (found here http://www.paraben-forensics.com/catalog/product_info.php?products_id=405) to do the device acquisition.
The MAGT log with a name like "<Blackberry server name>_MAGT_01_20090108_0001.txt" will be a listing of every action taking place regarding the delivery of messages/calendar items/etc.. to every blackberry communicating with the server. You will find them in multiple segments per day. This is the place to look if the timing of the delivery/deletion/forwarding of a message from a blackberry is at issue.
SMS – When configured to do so the blackberry server will log into a csv file the following fields:
"Name.ID,"Email Address","Type of Message","To","From","Callback Phone Number","Body","Send/Received Date","Server Log Date","Overall Message Status","Command","UID"
With a file name such as "SMSLog_20070927.csv" with one log being created per day.
The file is written out in utf16 so be aware of that if you to parse it out.

Blackberry Messenger – This is a blackberry IM program that according to my current research will not be logged on the server without creating an account to relay all the messages to. Without prior configuration the only way to recover these messages is from the device itself.

PIN Messaging – This is the PIN messaging log. PIN Messages are those messages sent between blackberries directly through the blackberry server directed to the PIN assigned to the blackberry by the server. By default the blackberry server will log into a csv the following fields:
"Name.ID,"PIN","Email Address","Type of Message","To","Cc","Bcc","From","Subject","Body","Send/Received Date","Server Log Date","Overall Message Status","Command","UID"
With a file name such as "PINLog_20070927.csv" with one log being created per day.
The file is written out in utf16 so be aware of that if you to parse it out. I'm writing a parser now to dump them all into a mysql database that I will post when I correct a weird multiline message that I've found. Special bonus it's a perl script that correctly handles utf16.

Phone Call Log – This is a log of all of the calls being made out of the blackberry devices, note this only applies to calls made on blackberries connected to this blackberry server. This includes missed calls, outgoing calls and incoming calls that I've seen to date. By default the blackberry server will log into a csv the following fields:
"Name.ID","Type of Call","Name","Phone Number","Start Date","Server Log Date","Elapsed Time","Memo","Command","UID"
With a file name such as "PhoneCallLog_20070927.csv" with one log being created per day.
The file is written out in utf16 so be aware of that if you to parse it out.

All of the CSV files will load into excel directly if you import them, otherwise if there is a large number of dates in question I would recommend parsing them into some kind of database so you can pull records by the user's name or PIN.

Depending in the current configuration of the blackberry server after the date in question or the changes you make to a server now in preparation (if you are internal) a large amount of responsive data that the user may not believe exists will be available to you. Don't expect your blackberry admin to be aware of this data existing but make sure to ask for a copy of the log director regardless.

When is Powerpoint file not a Powerpoint file? by David Cowen - Hacking Exposed Computer Forensics Blog

Dear Reader,

Today we will not discuss OWA again. Rather we will discuss a peculiar case of a temporary file that lead into a journey of discovery into Microsoft internals.

I was working a case Lockheed Martin v L-3, et al (6:05-cv-1580-Orl-31KRS), which has since settled, which involved amongst other things several files that were contained on a CDROM and accessed on a laptop. On this CDROM were lots of files and one of the issues in the case revolved around which if any of those files had been accessed on the laptop showing which information may have been exposed and/or transferred to the rest of the company.

So like a good computer forensic investigator I reviewed all of the recently used registry entries, the lnk files and the user assist records regarding any of the files known to have come from that CD. One of the files in particular had an extension of 'shs'. 'shs' files are scrap files made when a user is copy and pasting items such as powerpoint slides, in this case it was a powerpoint slide.

So I found the entries referencing that this specific shs file, which when loaded into powerpoint is a single slide, was accessed on three occasions. At times corresponding to these accesses I found a temporary file on the desktop that contained keywords relevant to the case and appeared by content to be a powerpoint document but no matter what tool I used it would not open it. All of my file signature tools regarded the file as 'data' with no specific file type.

The opposing investigator had the system this CD was burned form and thus had one significant advantage over me, he knew that the temporary file was related to the scrap file contained on the CD.

Sure enough when I renamed this temporary file that no tool regarded as anything to an extension of 'shs' it opened up right away in powerpoint revealing the same slide as contained in the shs file on the CDROM. This left the question, how did this file get created on desktop?

So I keep reiterating the CDROM for a reason, normally when temporary files are created in office documents they are created in the same directory as the file you are working with. When you are working on a file in a read only directory, like a CDROM, it will instead create the temporary file on the desktop.

So mystery of why the file exists solved! We already knew the scrap file was accessed and now we have corresponding temporary files to show that on the desktop.

The opposing expert was not deterred so easily, he pointed out that the temporary file sh60.tmp had the numeric 60 in it meaning in his opinion that it had in fact been accessed many more times than 2 since the 60 is actual hex for 96 so he claimed it was accessed approximately 95 times. This would a very large amount of accesses for a single powerpoint slide no matter what the contents so I was skeptical. We did some research to determine what creates the temporary file and found out it was a shared Microsoft library that many, many applications use including the application of hotfixes and service packs.

Each time a temporary file is created by anything that uses this shared temporary file library the counter is incremented thus explaining how we had such huge jumps between our temporary files left on the desktop and the discrepancy of the offset to the number of times the rest of the forensic artifacts showed the file being accessed.

So the morale of the story is, sometimes a temporary file isn't just a temporary file so be careful out there and always test your assumptions. In this case both myself for assuming the temporary file was just a temporary file and the opposing expert for assuming that nothing else would change the counter on the temporary file got to learn an important lesson.

Using OWA logs to make your Civil Case by David Cowen - Hacking Exposed Computer Forensics Blog

Hello Readers,

I will not be talking about OWA every time.

In our prior time together we discussed parsing OWA logs to determine who has been accessing someone else's account. For criminal prosecution (unauthorized access) or internal investigations this might be enough, but for investigations involving the civil court system you need to show that the information accessed and the time they accessed it corresponds to some claim such as tortuous interference.

The same OWA logs we looked at last time will allow you to do this, with some caveats. When you see a single entry to access an item such as:

" /exchange/USA/Attach/read.asp?obj=000000007C6A5AC4439BD948B2EDEC2B4701083907007DC649E6901ED711982E0002B3A2389C000000C0411400007DC649E6901ED711982E0002B3A2389C0000013340B20000&att=ATT-0-C9D9D5C63632DD439C1AF3C6A4B4AF8A-TOD9D1%7E1.PPT"

This is a request to open up an email attachment, the obj show here in the query is a unique identifier for the item within the exchange database. This means that if you replay that url while, and this is important, logged in as that user you will be able to bring up the exact same message that was viewed at that time (If it was not deleted).

If you attempt to access this object while logged in as any other user it will deny you, even if you login as the administrator. If you want to make sure the messages exist (meaning not deleted) restore the exchange server from a backup tape referring to the time period the message we viewed and replay it to the restored server.

These are the following asp pages that can be called by an OWA user according to about two years worth of logs from one case I worked:

/exchange/USA/LogonFrm.asp

/exchange/USA/root.asp

/exchange/USA/Navbar/nbInbox.asp

/exchange/USA/inbox/main_fr.asp

/exchange/USA/inbox/peerfldr.asp

/exchange/USA/inbox/title.asp

/exchange/USA/inbox/messages.asp

/exchange/USA/inbox/commands.asp

/exchange/USA/forms/IPM/NOTE/frmRoot.asp

/exchange/USA/forms/IPM/NOTE/read.asp

/exchange/USA/logoff.asp

/exchange/USA/Attach/read.asp

/exchange/USA/logon.asp

/exchange/USA/forms/IPM/NOTE/commands.asp

/exchange/USA/forms/IPM/NOTE/cmpTitle.asp

/exchange/USA/forms/IPM/NOTE/cmpMsg.asp

/exchange/USA/errinbox.asp

/exchange/USA/forms/IPM/SCHEDULE/MEETING/RESP/frmRoot.asp

/exchange/USA/forms/IPM/SCHEDULE/MEETING/RESP/read.asp

/exchange/USA/forms/IPM/SCHEDULE/MEETING/RESP/commands.asp

/exchange/USA/options/set.asp

/exchange/USA/calendar/main_fr.asp

/exchange/USA/calendar/title.asp

/exchange/USA/calendar/events.asp

/exchange/USA/calendar/appts.asp

/exchange/USA/calendar/pick.asp

/exchange/USA/forms/IPM/SCHEDULE/MEETING/REQUEST/frmRoot.asp

/exchange/USA/forms/IPM/SCHEDULE/MEETING/REQUEST/mrread.asp

/exchange/USA/forms/IPM/SCHEDULE/MEETING/REQUEST/commands.asp

/exchange/USA/contacts/main_fr.asp

/exchange/USA/contacts/title.asp

/exchange/USA/contacts/peerfldr.asp

/exchange/USA/contacts/messages.asp

/exchange/USA/contacts/commands.asp

/exchange/USA/finduser/root.asp

/exchange/USA/finduser/fumid.asp

/exchange/USA/finduser/fumsgdef.asp

/exchange/USA/finduser/fumsg.asp

/exchange/USA/finduser/details.asp

/exchange/USA/forms/REPORT/DR/frmRoot.asp

/exchange/USA/tshoot.asp

Of these we care about the following:

This is a user logging in - /exchange/USA/LogonFrm.asp

This is a user requesting to read a specific message - /exchange/USA/forms/IPM/NOTE/read.asp

This is a user opening an attachment - /exchange/USA/Attach/read.asp

This is a user composing a new message - /exchange/USA/forms/IPM/NOTE/cmpMsg.asp

This is a user reading a message request - /exchange/USA/forms/IPM/SCHEDULE/MEETING/REQUEST/mrread.asp

If you parsed our just these commands identified by the logged in user you could see what specific emails, meetings, and attachments a webmail user had viewed, created, sent using OWA and the time on which they did. Using these times and matching the ip address to the suspect you can then combine the information accessed, to the time it was accessed, to the benefit they received by having that information at that time.

As an example, in the case Exel Transporation Services Inc v. Total Transportation Services LLC et al (3:06-cv-00593) I used this to uncover a large industrial espionage case. First I used the program in the prior post to find which accounts were being used to access other email accounts in the system.

Then I looked up the IP Addresses and found out one of them was actually registered to one of the ex-executives of exel directly on ARIN. We then broke out just the accesses used by those accounts (I mean really why else would the blackberry server administrative account or the voicemail server be logging into a website .. something we had to explain to counsel) into a database divided up by type of item accessed (email, attachment, calendar).

The next part was more difficult, we had to replicate their exchange network, AD controller, etc.. to restore their exchange server backups and replay those months to find out what our suspects were viewing. This included almost every decision maker within exel and according to the filings I read about $120 million dollars in lost business as they were able to read the contracts sent to customers during a bidding process and always beat them.

We fed the urls into a GUI automation tool that would interact with the web browser and save the emails and attachments into MHT (full website archive) files for the lawyers review. I couldn't within the time frame get a pure perl program to work the way I needed it to.

For more information read this news article:

http://www.bizjournals.com/memphis/stories/2006/08/21/daily30.html

The case was settled out of court with a public apology written by TTS. The final stone in my understanding that led to settlement was when we matched the TTS OWA logs to the Exel OWA logs and showed the suspects logged into the TTS server with their real user name, with the same ip and at the same date/time, as they were logged into the Exel OWA server with their administrative accounts.

I hope this was useful, I can post parsers I wrote if you think it would help you in the future.
