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.

Properly implemented, this could mitigate attacks using email-borne Office malcode.
