Cluster-OneNote-uuids

Python script for clustering OneNote ('.one'/'.onetoc2') files.

Microsoft has the habit of storing various UUIDs/GUIDs in generated files - USING .NET GUIDS TO HELP HUNT FOR MALWARE. For .NET files, the typelib GUID is unique to each Visual Studio project, while the mvid GUID identifies the specific build. Virustotal allows hunting for samples using these identifiers - VirusTotal .NET GUIDs reference.

In the case of OneNote, according to personal observations and MS-ONESTORE, we have guidFile for each OneNote file (equivalent for typelib GUID) and guidFileVersion for each change to that file (equivalent for mvid GUID). Long story short, if we take an existing OneNote file and update it, the guidFileVersion will change but the guidFile will remain the same, allowing us to track different versions of a file.

The clustering uses the guidFile field of OneNote files. All files having the same GUID are added to the same cluster.

For detailed information in regards to a OneNote file, one can use pyOneNote.

Quotes from Microsoft docs:

guidFile (16 bytes): A GUID, as specified by [MS-DTYP], that specifies the identity of this revision store file. SHOULD be globally unique.
(...)
guidFileVersion (16 bytes): A GUID, as specified by [MS-DTYP]. When either the value of cTransactionsInLog field or the guidDenyReadFileVersion field is being changed, guidFileVersion MUST be changed to a new GUID.

The guidFile is stored in 16 bytes starting from offset 16 relative to the start of the file.

Case study

For testing, I looked at '.one' files from MALWARE bazaar. Here are the results:
