Hi all, I am new here and hope that someone can help me out with this. I am looking for ways to find hidden information in both Word and PDF files. These files did not originate on my computer. They were sent to me. I have a Mac operating Microsoft Word 11, and Adobe Acrobat Pro....for example


- original creation date (whenever I look in the Finder, the creation date is the date it was saved by me!)

- original author (or even originating IP address or any info on who, where, when the document was created)

- any other 'hidden' data, such as objects, additional spaces, white text etc.


Here is what I have tried so far...it might be all that there is, but thought I'd check with the expert community..


- Microsoft Word - properties, user information, track changes, opening document in TextEdit (apparently PC users have Document Inspector in their Word software, this would be great, but Mac doesn't have it)

- PDF - all info available under properties, had a play with "preflight", but don't really understand it


Essentially I am concerned that the documents have not been written by the person who says they wrote them, but I need to be able to find evidence of this. Any help would be appreciated!


Thanks :)

You may be able to pull the info using a live linux disk like Ubuntu. I was able to pull owner information and creation date on a pdf file by right clicking, selecting properties and looking under the Document tab.


As far as the Word Document. If it's a docx document then you can rename the extension from .docx to .zip. Open the zip file and open the xml files in the firefox browser by double clicking each. There may be XML files in each of the unzipped folders. One xml file to look for is called Core.xml. Libre Office, which is included in the live disk may be able to pull ownership data and creation date too.


You can probably do this using your MAC also. Rename your Word docx extension to .zip and open all the xml files you find in the unzipped file.
