A number of articles and papers have recently been published on the Internet concerning the problem of information leakage through hidden data in various published online documents. This has been know for a number of years and I highly suggest that everybody using .doc and .pdf to review the "properties" section where a large amount of hidden information is mentioned about your document that can be discovered quite easily according to the following articles and research papers:
Scalable Exploitation of, and Responses to Information Leakage Through Hiddent Data in Published Documents by Simon Byers
http://www.user-agent.org/word_docs.pdf
Recommendations vary from not publishing documents on the Internet to scrubbing all the documents prior to publishing online. A quick search showed very little available on documents scrubbers to protect against exploitation and if anyone knows of freely available and simple to use "Document Scrubbbers" please email me by clicking here so I may compile a list and publish on this blog.
