A common cyber attack is to send a user an Office document (Word, Excel, PowerPoint) containing malicious code that infects the user's computer and proceeds to do the miscreant's bidding. Targeting of users has gotten so sophisticated that advice such as "don't open files from people you don't know" is no longer effective. MOICE, the Microsoft Office Isolated Conversion Environment opens Office documents before the Office application, converts it to a format that does not "support" malcode and then invokes the application with the newly cleaned document. Properly implemented, this could mitigate attacks using email-borne Office malcode.
