If I read that correctly, it requires someone to install malicious code to the
box and won't persist if someone upgrades it later to non malicious code.

What the screenshot of NSA 'implant' says is persistently broken, through
malicious BIOS, which dynamically rewrites kernel in-memory post-boot.

The netscreen hack, is cute, but it's rather on the same difficulty level as
it is to build savegame editor for game.
