Isn’t that attack only viable within minutes of a machine being powered down?
Not even, try seconds at most.
All things considered, a cold boot attack is only remotely feasible if the system is powered on when the attack begins. If it’s powered off for any length of time, your memory will have decayed past the point of it being usable for the attack.
That might work if the zionazis weren’t actively showing they want to cleanse Palestine so they can move in.
That actually is correct, because if you power your system down ahead of time, this attack is meaningless since there is only a VERY short window where this attack works. From your link:
Attackers execute cold boot attacks by forcefully and abruptly rebooting a target machine and then booting a pre-installed operating system from a USB flash drive, CD-ROM or over the network.
If your attacker only has your cold machine that’s been off since well before you hit the checkpoint, they can’t do shit with that attack. At best they can boot the system up to verify your system operates as intended, but you don’t have to provide any of the credentials to finish booting or unlock the TPM to load the key material into memory.
Rossman posted a video a while ago about how Microsoft updated their site without noting they updated it to gaslight their customers into thinking it’s always said that.
There’s a reason these companies are trying to kill the archive sites, it lets people call them on their bullshit.

FYI, the cold boot attack is only viable for a handful of seconds before your memory decays enough for it to be worthless for that attack.
Powering your system down yourself prevents this. Just make sure your system doesn’t have fastboot enabled or hibernates instead of a true power off.
