Microsoft Windows + Outlook Email + Attached word document = the Drake equation for internet security. No matter how secure each of these things are individually, when added together infection becomes inevitable.
Why does outlook have to pass such documents to Word? Why does Word have to open and run macros so willingly? Why does Windows allow word to talk to the internet so easily? I just don't understand the use case these links are meant to address. Are there really so people out there installing software via links inside word documents? That this has to be a seamless user experience? There are so many opportunities to limit such such infections. Why do we still tolerate this?
