Daily Blog #603: Sunday Funday 1/20/19

Hello Reader,
            Last week's challenge brought out some great research and new tools. I hope that this streak of great responses continues through 2019! Let's switch focus back to the Syscache hive for this weeks challenge.

Daily Blog #602: Solution Saturday 1/19/19

Hello Reader,
        This weeks' challenge has an interesting twist, I have two answers but neither was submitted before the deadline. So I thought I would post the two answers for everyone's benefit so it's not lost to the twitter timeline.

The Challenge:

In Windows 10 what behavior appears to determine if a program will show up in the UserAssist entries with 0 run count versus actually tracking a run count and last execution date

The Answers:

Matt Seyer: 

https://medium.com/@forensic_matt/no-run-counts-in-userassist-4f2a78cb9e2c

Matt worked up and tested three hypotheses for conditions where the UserAssist value did not get set or updated. Matt also released a really neat tool that will allow you to monitor UserAssist values in real time which will make testing much easier.

Maxim Suhanov:

Maxim tested a different method, he noticed that if GUI apps were executed from the command line (which should include exec scenarios within other programs) that the same behavior occurs. 

The common thread that I can find between all of these tests is that UserAssist is tracking executions outside of the direct user context now. This means ... you guessed it ... more testing! I think this helped leap forward quite a bit but I look forward to really pushing this out over the next week.

Daily Blog #601: Live registry triage and testing

Hello Reader,
          Well I attempted to do a test kitchen tonight but VMWare Workstation didn't want to cooperate. What I wanted to show is summarized in the below blog post from Eric Zimmerman:

https://binaryforay.blogspot.com/2019/01/locked-file-support-added-to.html

Eric has added the ability for his registry tools and the MFT explorer to be able to access the locked live files running on the live system. This means you can now access shellbag data with dates, view and search registries, parse amcache hives, run registry plugins and parse MFTs all without imaging or extracting files from the live system.

This is a pretty big step and it will require running the programs as the administrator in order to access the raw disk. I hope you take a moment to give them a spin as I will when I get a VM to boot!

Daily Blog #600: Windows 10 Search Artifacts are going to change again

Hello Reader,
            I saw this article over on the verge:
https://www.theverge.com/2019/1/16/18185490/microsoft-cortana-windows-10-search-changes

In this article they describe how Cortana is going to be separated from the search function. Currently we find the Windows 10 search artifacts in the NTUSER registry under the \software\microsoft\windows\current version\search. So keep an eye out for this change as we expect changes in how this data is stored and possibly new entries for cortana.

This is interesting since Cortana has been rapidly changing artifact wise and a return to more locally stored Cortana artifacts would be welcome.

Daily Blog #599: Forensic Lunch Test Kitchen 1/16/19 Syscache Server 2008 R2 Mimikatz

Hello Reader,
   Tonight we just had a short testing session (8 minutes of actual testing) were we checked in on last nights test. Here is what we learned:

• The time delay did not effect our results
• A shutdown/power on did not add a new entries
• The registry explorer and hasher entries still had no hash
• We still saw no entries for the other mimikatz executables

On the next broadcast we will be testing the same behavior in Windows 7 and parsing the whole MFT and Syscache rather than individual records to make sure we aren't missing anything.

Daily Blog #598: Forensic Lunch Test Kitchen 1/15/19 Syscache Mimikatz Server 2008 R2

Hello Reader,
       Tonight we returned to the test kitchen to try to solve the mystery of the Multiple mimikatz executables now showing up in the Syscache

Tonight we learned:

• Syscache does not appear to duplicate entries by hash
• We got some entries to appear without a hash
• We are giving the VM enough time to run its background processes to get the Syscache full written to with a new test tomorrow night
• The last write time does not appear to be updated when the program is executed again
• 64bit and 32bit executables are being recorded

Daily Blog #597: Tool Spotlight MD Viewer

Hello Reader,
          I was out late helping a friend so rather than a test kitchen tonight I'm going to do a tool highlight. David Dym our colleague at G-C Partners, LLC has written a number of tools we use like:

• ShadowKit
• MetaDiver
• SqliteDiver

and now he's come out with a new tool MDViewer or Meta Diver Viewer. 

MDViewer let's you quickly view all of the metadata of a file and is built on top of Apache Tika with the ability to drag and drop files on it to view not only metadata but also hex/strings and more. 

You can grab a copy here:

Daily Blog #595: Solution Saturday 1/12/19

Hello Reader,
        I had two great submissions this week and one of them surprised me because it was from my own fellow g-c'er Matt Seyer. Matt won this weeks competition because he took one step farther in his testing to show not only what the new tables in the Server 2019 SRUM database meant, he also showed where to go in the registry to get the answer.

The Winning Answer:
Matt Seyer (@forensic_matt)

Sunday Funday Submission

The Challenge

Server 2019 got SRUM, what if any differences are there between SRUM on Windows 10 and SRUM on Server 2019?

Methodology

Compare the SRUM database schemas of a Windows 10 system and Server 2019. The most obvious differences should appear in the database schemas. Because the SRUM database uses the Extensible Storage Engine (ESE) format, we should work directly with the ESE database itself and not use tools that interpret its data into a different format (many tools will convert the ESE to SQLite). Because SRUM uses Extensions that are recorded in the SOFTWARE hive, the SOFTWARE hive should also be checked for differences.

Windows Versions Used

The following versions were used for generating the data in this research.

Server 2019 Version: Windows Server 2019 Standard (Desktop Experience)

Windows 10 Version: Windows 10 Enterprise

Table Differences

The following table schemas are resolved with a script (srum_schema.py) that uses pyesedb and yarp to resolve SRUM data. pyesedb allows us to work with the ESE format and yarp allows us to work with Registry and take transaction logs into account.

Base Tables

After reviewing SRUM’s base set of tables (tables not in the extensions), they appear to remain the same across Windows 10 and Server 2019.

Extended Tables

The differences between Windows 10 and Server 2019 start appearing when looking at the “Extension” tables. See the section Resolving Extended GUIDs for more information on registered Extensions and their enumeration. It would appear that DLLs register the Extension and thus it is expected to see differences of these tables between systems depending on services or application that exist. That being said, let’s look at some common tables.

Windows 10	Server 2019 Desktop Experience	Notes
--------------------------------------- Table: {973F5D5C-1D90-4944-BE8E-24B94231A174} [Windows Network Data Usage Monitor] -- Extension Key Values from SOFTWARE hive -- : Windows Network Data Usage Monitor DllName: %SystemRoot%\System32\nduprov.dll --------------------------------------- AutoIncId -> INTEGER_32BIT_SIGNED TimeStamp -> DATE_TIME AppId -> INTEGER_32BIT_SIGNED UserId -> INTEGER_32BIT_SIGNED InterfaceLuid -> INTEGER_64BIT_SIGNED L2ProfileId -> INTEGER_32BIT_SIGNED L2ProfileFlags -> INTEGER_32BIT_SIGNED BytesSent -> INTEGER_64BIT_SIGNED BytesRecvd -> INTEGER_64BIT_SIGNED		This is where things get interesting. The “Windows Network Data Usage Monitor” table does not seem to exist on my Server 2019 Standard fresh install. This has been a very useful table and is used by SrumMonkey to generate meaning full network data reports. Upon examining the Server 2019’s Windows\System32 folder, no ‘nduprov.dll’ exists. Though Server 2019’s table “{EEE2F477-0659-5C47-EF03-6D6BEFD441B3}” (SDP Network Provider) appears to be some what of a replacement for network byte usage. [Further down in table]

That being said, it lacks interface IDs.

Resolving Extended GUIDs

As with Windows 10, Server 2019 maintains the SRUM extended GUIDs and format under the SOFTWARE registry key `Microsoft\Windows NT\CurrentVersion\SRUM\Extensions`. This key has multiple sub-keys which are the GUIDs. For each GUID key, the default value is the descriptor of the GUID. See below for example:
