It was predictable, and I'm certain predicted by many.

These AMTs/MEs/whatever they call them are full-blown computers with non-trivial firmware/software. The question is: do Intel and AMD put all that much effort into making that secure? (That's quite aside from the possibility of intentional backdoors, which one would think would be reasonably secure so that only NSA and friends could use them.) The answer is "almost certainly not enough effort". This sort of device calls for using Coq or similar provably correct software construction -- it is much too critical to do otherwise if you're going to make it impossible to disable these things.

I guess we just have to filter these ports for a while now -- a big hammer for a big problem.

It's also time for customers to insist on these things being off by default.
