Security is constantly used as a guise for removing consumer rights and as someone who has been in the security industry for about 9 years I’m so sick of it.
First and foremost, everyone please understand: the user should be allowed to opt into your concept of insecurity: you do not know their threat model and you do not know their risk tolerance.
Using exploits in low level drivers in the wild is approaching APT level, and even if there were a simple one to use it’d likely be useless without some sort or local access to the device (bar some horror show bug in a Bluetooth or WiFi firmware). The risk is incredibly low for the average person. I’d put it pretty close to 0.
Wire transfers aren’t instant and for large sums (your inheritance) the banks will likely require more than just a request from your app. If the bank cares about that then they can also use the attestation APIs which would be more than sufficient, as much as I hate them.
This boogey man of the APT going after my technologically illiterate <family member> with nation state level exploits needs to die. Long ago we entered a new era of security where it just isn’t worth it to waste exploits. Especially when you can just text people and ask for their money and that works plenty well.
Security is not a valid reason to soft brick consumer devices at some arbitrary end of life date.







Yes I’m not going to take some “survival of the fittest” nonsense approach to security: consumers need securely built devices and software. This is the first line of defense always: we need to make things secure and then have secure defaults according to whatever we decide “secure” means in the context of our widget or software. Then we need to provide “advanced” (or even just “ignorant but risk tolerant”) users with the ability to change the device or software to match their definition of “secure”.
The easiest example is secure boot. Your laptop likely has a key provided by your OEM and likely Microsoft’s key preinstalled. This is a valid “secure boot” path for the average user, provided your OEM and Microsoft don’t get compromised, which is APT territory. However you are provided with the ability to use a different key if you know how to do that. You have thus opted in to protecting your own private key but now you have more control over your device. This design is notably absent in phones, which is absolutely bananas and actually less secure in some threat models
You could extend examples like this if you wanted. One could easily imagine a device that does soft brick itself after the EOL date to simply protect people that are ignorant of the potential risks, but also provides an advanced user with the ability to revive it in a “less secure” state. The less advanced user will then have to either learn something new or buy a new device.
