All AMD Processors Since Phenom II Have BadBIOS Circuitry That Leaks to the Military

Title gives my conclusion from empirical events I witnessed and inside info. PSP runs on the same circuit, but isn't the backdoor per se, which has been around for much longer.

The same way AMD was able to change the crypto algorithms for the Zen chip they licensed to China, they can change how the CPU behaves at any system, even those already deployed. This can also be used to sabotage any program or computation, making BadBIOS vastly nastier than Stuxnet.

American military made a grave mistake to partner with the morons of the Brazilian military, who are letting knowledge of this spread like a fire (and misusing it for petty profit and inside jobs to justify a police state). Israel, UK and France also have access, but are much more professional.

their first line:

empirical evidence from their experience and inside information.
trustworthy? you decide.
reading helps though...

These claims are based on

These claims are based on some programmers and other IT security people's claims, that are purely talking about the software side of things.

The physics side of it makes me frown... In order to emit ultrasonic waves over a good enough range (for even shadow-networking someone who's sitting in a park, for instance), you need to allocate a lot of power on the emitting circuits. Also you need a special type of antenna/transducer for ultrasonic waves... Long range ultrasonic devices like dog repellents are pretty circuitry.

Furthermore, with so many electronics technicians out there, why no one (AFAIK) has found the presence of such covert circuitry in laptops?

@critic
how does it work tho

I'd not be surprised after the bugs found in other chips awhile back, but I wonder what the logistics of it would be, in terms of actually getting vast quantities of data out without being detected. Also, if there's backdoors in everything then why aren't more people getting caught (for example) for DNMs or CP? Is it one of these capabilities (like using mobile phones as bugs) which they rarely use so as to keep them unknown? Do we have even one case of confirmed use of the supposed backdoor?

Also, is there a solution here? I don't think there's any open source microprocessors. I guess China make their own, those might be safer if you're in the US?
