Excuse me, what?

Imagine thinking there is such a thing as digital security. Imagine thinking digital 'money' can ever be secure.
The former is for granted, but the latter ... we haven't heard of a "hacker" becoming a trillionaire overnight, yet, and even "analog money" is handled with (possibly equally vulnerable) systems, from things like SWIFT to small local banks' servers.

Once again I'm reminded how the more I learn the less I know.
I recognize some of those words, but can't follow the whole thing.
What does this mean in a practical sense?
Practically speaking, if you can perform the unlock procedure, you're able to use these undocumented instructions to modify the microcode running on the machine. I would imagine the possibilities from that are nearly endless.

can somebody explain in detail what this means and the implications? was this vulnerability an oversight or intentional is the bigger question
It's a way of making a machine break, that most people are unlikely to think about.

Is it a new one?
Fun method they had of discovering them, I suggest everyone who missed their talk(s) watch them (not sure which conference has the best recording, though).
