| Multiple crypto-experts said that the safest crypto wallet is a recent iPhone in airplane mode which is only used for this purpose. Because it's much harder to implant that your average hardware crypto wallet. |

| On the other hand, the attack surface of an iPhone is huge compared to a dedicated hardware wallet, and it's hard to keep it in airplane mode and actually transact your coins. |

| Why is it harder to implant? |
| |
| ▲ | bri3d 2 hours ago | parent | next [-] | | The hardware is much more sophisticated, miniaturized, and high-speed, and the supply chain is much more generic; a Ledger is a really primitive piece of hardware with a simple display interface and a ton of empty space inside it. An iPhone has no wasted space and extremely high-speed onboard buses that would be hard to sniff. Additionally, with Ledger, you know that every customer is going to be using the device to access crypto, so it's an easy target nearer the head of the supply chain. With an iPhone, you have no idea what end-user to target the implant against. | |

Crypto thieves would have to have compromised the entirety of Apple's supply chain and found space inside the iphone to fit a whole spy chip (of which there is basically none). | | |

| ▲ | r_lee 35 minutes ago | parent [-] | | right, so you'd have to know the store with your victims upfront, know which ones to give these highly expensive implanted iPhones to (or have a lot of units), be able to always bring enough for the specific colors the customers want.... |

| How about if you build your own airgapped hw wallet? There should be plenty folks here who would be capable of doing so. (Doesn't even have to be the most hardened and audited implementation ever since you won't release this to anybody.) This makes you vulnerable to purely very targetted attacks. As long as the cost of sucha single-target attack isn't substantially below its potential upside, you should be safe. Otoh, it's only meaningful if you have more than just toy assets in there. There should be a range between those two though that would contain lots of folks comfortably. |

Yeah, the problem with "crypto hardware wallets" is the same as the problem with "secure phones for drug dealers" - they are an extremely juicy targets, you KNOW that any user of them is your target. |
