Daily Blog #595: Solution Saturday 1/12/19 - Server 2019 SRUM Database Challenge Solution

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 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:
