    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.
