Hardware Backdoors
This cluster focuses on concerns about backdoors, implants, and compromises in computer hardware and firmware, emphasizing that untrusted hardware cannot be secured by software alone due to supply chain risks and detection difficulties.

Not good enough, your hardware has to be secure too or they can leave an implant in any of various firmwares.
Can't hardware have backdoors? How about the firmware?
You can't run trusted software on untrusted hardware. If someone has a backdoor in your ME, you can't protect yourself from it.
It is the potential of hardware compromise that concerns me. Software can be wiped, but if the hardware itself contains backdoors, software can then be install at any time. Furthermore, given the global supply system, its so hard to confirm that any hardware is not compromised.
Where is the hardware? I call bullshit until someone produces compromised hardware.
tl;dr - Nothing is secure. Even Intel's specially designed Trusted Execution Technology (close to the Trusted Platform idea) has known flaws. You can be hacked at levels which you cannot control (firmware). It's tricky (not a script-kiddie level exploit), but possible and many existing holes are not published/known, because researchers would rather do something interesting than uncover yet another bug using the same technique. If you have government-level influence, start complaining to Intel (e
It's not secure if the hardware compromised. Not much is.
Threat model again: what if you're concerned that they themselves are unaware their hardware's been compromised?
It can always be tampered with if you have access to the hardware
possible the hardware is compromised
