Kevin Beaumont has posted a fantastic (and pragmatic!) guide for best practices when working with Office documents. His guide to simple configuration management will dramatically improve your security posture by making some changes to how trustworthy Office documents are.
OLE is more popular than ever, and for all the wrong reasons.
