I'm not an expert in BTC storage, but as far as I understand such an attack could have been prevented if the owner invested in a hardware wallet for $100-200. As the final step in a transaction would be to sign it on your ledger/trezor device, and would be much harder to phish.

This was my first thought too. Hardware wallets show transactions on their own screen so the amount and destination address can be confirmed on-device before the device signs the transaction, which seems like a great tool to avoid this kind of issue. Anyone that owns more cryptocurrency than a hardware wallet costs really needs to have a hardware wallet.
