New (to me) BT Open Reach Scam

Note:
I'm convinced BT Open Reach would know what speed broadband they were supplying but never, I'll repeat, never allow anyone to access your machine using the Terminal app. I often joke it's appropriately named but it can be terminal in the wrong hands. (Terminal is a useful tool for UNIX geeks who know far more than me but want to access the very depths of their Mac in ways that nothing else can.)
