The ‘paul manafort‘ example leads to questions … how can you change the Author name in an Office document? How does the FBI know that the ‘paul manafort’ name in the Word document really is him editing?
It’s easy enough to go to File | Info to see and change the document Author name. We did that in a few seconds …
Click the ‘Add an author’ to type in a new name. Right-click on an existing author to remove the name.
Keep in mind that just removing a name from the Author field may not delete other mentions of the person in the document. For example, in the edit/revision details of a document.
Go to Windows Explorer, right-click, Properties | Details to see the file details. These details are saved separately from the document info but are usually the same because Office keeps them in sync.
Remove Author in document and file details
The Document Inspector in Office will remove the Author information saved in the document and the file.
Was it really Paul Manafort?

What’s not mentioned is the other forensic details available that could link the Word document to a particular computer, person or location.
