Document Threat Lab

A document can contain ordinary links and metadata as well as material worth investigating. This workflow starts with structure, not an assumption that every extracted string is a threat.

Demonstrated on constructed training data

What does the document's structure reveal before it is opened in an office application?

Start with

  • A valid constructed DOCX package with an external hyperlink and no VBA macros.

What you can take away

  • Static package information, source hash and extracted indicator strings for the demonstrated DOCX.
Static examination of an invented DOCX invoice identifies its OpenXML container, one external hyperlink and no VBA macros. The source hash and package paths remain visible; the document was not opened in Office. View full screen

Open the screenshot and choose “View actual size” to read the records at their original resolution.

A practical starting point

How the workflow fits together.

  1. Identify the document and inspect its package structure.

  2. Review links, available macro indicators and extracted strings beside their source paths.

  3. Separate ordinary document components from findings that require further examination.

Start with your requirements

Bring a sample question.

Ask us to demonstrate this workflow with suitable public or constructed material. Do not send confidential evidence in an initial enquiry.

About the screenshots and illustrations

Application screens are selected from the September 2026 Acorn screenshot pack. Captions distinguish native setup views, constructed training records and public-corpus results. They are not private client cases, and a displayed control does not establish that every operation was completed.

Relevant public sources include DeepBlueCLI training event logs and Plaso test data. Check the relevant source terms before redistributing an underlying dataset.

Workspace scenes and sector mascot variants are generated illustrations. They do not show actual police, judicial, military or university deployments or endorsements. The original Squirrel Forensics identity is retained.

Zoom in, then scroll to inspect the detail.
