Re: Hacking the processor
I think it is great. If you favorite hat color is black.
Think about the possibilities.
1. Malicious website uses social engineering tricks to let user grant it WebUSB access.
2. Using said access, it hacks into a piece of hardware which communicates over USB protocol but which may even be a physical part of your computer (e.g. laptop keyboard or touchpad). So nice try that you filled your USB ports with epoxy but it didn't help.
3. From the compromised device it now hacks back into your computer using the IME vulnerability.
It doesn't even matter anymore if you run Windows, macOs or Linux!
