Our current file blocking policy blocks zip files, however, users are getting blocked from downloading compressed Office documents. Office 2007 and 2010 save files in the docx, pptx, xlsx type extensions. They are technically zip files, since you can change the extension to .zip and it will open in a zip program.
The thought was to create a custom signature to allow these files, since the following seems to be persistent.
The file starts with: 50 4B 03 04 14 00 06 00 08 00 00 00 21 00
At offset 1E, it contains: 5B 43 6F 6E 74 65 6E 74 5F 54 79 70 65 73 5D 2E 78 6D 6C (this is the description for the file name [Content_Types].xml, which appears in these types of files)
Is there a way to make this work?
