In July, we released a beta Office file format viewer application called OffVis as a downloadable tool. We are pleased today to announce an updated version of OffVis and a 30 minute training video to help you understand the legacy Office binary file format.
The community response to the release of the OffVis tool on July 31st has been great. Thank you for the feedback! We are releasing this new version 1.1 of OffVis in response to that feedback. This release introduces several requested new features and fixes bugs. Here are the highlights:

You can learn more about OffVis from our original blog post about the tool or an article written by Russ McRee in the ISSA journal. You can download the tool at http://go.microsoft.com/fwlink/?LinkId=158791
Office legacy binary file format training video
Bruce Dang and Nick Finco from the MSRC Engineering team put together a 30 minute training that describes the legacy binary Office file format and describes how to parse it. Our Bluehat team agreed to record it and host it on the Bluehat technet site. You can view the video at http://research.microsoft.com/en-us/UM/redmond/events/BH09/lecture.htm. In less than thirty minutes, they provide in-depth technical guidance, including full-screen demos. This video is geared toward security analysts, virus researchers, IDS signature authors, and security professionals.
