Use a device that’s mass produced enough it can’t be targeted e.g a MacBook, then keep it airgapped and don’t do normal computing on it.

Hardware wallets are air-gapped. The issue here was a distributor got acquired and then snuck a chip in that could read the spi link between the microcontroller and the screen. The chip had its own cellular modem and could send the passphrase that was shown on the screen to the attackers.

		If you sell a device specifically for storing large amounts of liquid assets, that puts a huge target on that device. You are basically asking for supply chain attacks An ordinary MacBook does not have that issue. If you are a high-value target, you can further decrease your risk profile by buying it from a random physical store, further preventing targeted attacks.

		The post you're replying to is arguing that it wouldn't be feasible to do that with a MacBook (at least if you buy it off the shelf at Best Buy).

		Boy that was a slog, to dig deep enough through the slop to find the technical details… In retrospect @gigachad’s summary is worth as much as both articles combined, but for the Clauded technical source (with pictures!) that Ledger’s Claude-release refers to: https://www.tibane.net/research/ledger-nano-x-implant

		Nobody said hardware wallets aren't air-gapped. They said take something normal and usual enough not to be an attractive target for bespoke crypto stealers, and then airgap that to make your wallet.

airgapped pre crypto devices are extra safe: break out the ti82! don’t buy a ti82 for this purpose, it has to be one you had in your closet. If a blog post describes how to code it in TiBasic then affiliate links a calculator in ebay, well…

Qubes OS can be more secure than airgapping in some cases: https://doc.qubes-os.org/en/latest/introduction/faq.html#how...
