So, this has been making rounds for a few days already after yet another (and then two more...) 0day in MS Office was discovered, but it got me thinking. The issue is that some orgs (NASA is mentioned here) chose to "block the receipt of Microsoft Word documents coming in to the space agency's core computer network as e-mail attachments" this time.
Would you do this? Or will your business units eat you for lunch and have nothing left for dinner? Now, almost everybody blocks EXE and COM as well as VBS on their gateways and it is seen as a reasonable practice. But DOCs?
