The short version is "yes". The long version is "maybe".
Though, its been a fact of life for intel and amd for at least a decade at this point if not even more (I think IME came out in the early 2000's).
The only real solutions against the bullshit is to have very strict network security and blocking inbound/outbound traffic and never putting the computer to sleep and shutting it down every time you are no longer using it (cold boot attacks exist but fully shutting down makes them harder). Oh, you should also make sure the network and power cables are disconnected. I know it sounds stupid/paranoid but it's not. There are a LOT of even college level projects that have exploited "offline" systems.
Can you tell what I spend much of my not-so-free time on?
lol. we all appreciate it too!!
