Microsoft Pluton Processor inside any AMD/Intel/Qualcom processors from 2022
(1/3) > >>
RoGeorge:
Did any of you knew about this? 

Microsoft convinced PC processor designers to embed a Microsoft Security Processor core, Pluton, inside the hardware of any normal processor.  Agreed in 2020, first models of AMD Ryzen 6000 laptops ready in 2022.  Updates for Pluton core through Windows Update only.  Part of the Microsoft chip-to-cloud, though Windows or not, Microsoft will control any processor.

Well, the first reports: https://www.semiaccurate.com/2022/01/18/amds-new-cpus-may-be-safe-to-deploy/
NOT linked  in the previous article; nonetheless, the problem raised in both is serious; personally, I will NOT boy a CPU with Puton.

Oh.. this sounds awfully familiar with the Apple Studio device not accepting "SSD" upgrades. Obv they also added a SSD controller inside the M1 chip, but if the (filesystem) encryption keys are stored *inside* the CPU package, then you'll almost likely need a software vulnerability to get them out. It depends if there a possibility to do so. I suppose the keys won't be system exposed, but you can only list, create and delete keys.

Sounds like a recipe for disaster for anyone doing data recovery, wants to swap out SSDs with other machines.. all the reasons why you wouldn't use disk encryption tied to a systems keys. And knowing Microsoft, I sincerely hope they play nice with OSS and help them with proper implementations for it.

In terms of BIOS I'm not sure how useful this is, because that's part of the chipset. If the remaining vulnerability is sniffing traces on the PCB, then I imagine that's a very limited attack vector that no one should be concerned about. So if TPM protects the BIOS firmware/rootkits, then that should be fine right?

Frankly ..  what does anyone expect from them?  This is not new

Their business has always been using the filthiest  methods available always imploding better products to force theirs

Claiming property of the hardware and forcing whatever to suit their greed no  matter consequences

This is by no means new.. these  assholes started this  slightly different method to ensure 100% property of the PC.. the same time they love *NIX..

TIME TO SAY NO  MORE IN LOUD AND CLEAR  VISIBLE SOUND..

just ditch them in proper  place

I don't like where this is heading. Remember that Gates character and his monopolistic pursuits with Internet Explorer. Eventually, some CPU variants might only allow you to run the Microsoft O/S and not Linux. Or to run Windows, you must purchase a particular CPU variant - at a premium cost of course.
