> In other words, the adversary in your threat model is the service provider - and in this case, Apple. And what good is that encryption, if Apple obviously can do almost anything with your device?

The adversary in this threat model isn't the service provider. The adversary is someone attacking the service provider, like a hacker or a government with a warrant, and getting access to Apple's storage of your data.

Now of course it's not impossible for such an adversary to also defeat other systems at Apple and get your data another way, for example by controlling Apple's ability to send over-the-air updates to Apple devices. But I think that is a sufficiently distinct threat that it's not worth dismissing solutions to the first threat. That would be like dismissing the importance of a web server storing passwords salted and hashed, since attackers could just use a totally different attack to bypass the web server's database access control. Another way to illustrate this might be to point out that attackers can physically coerce you to hand over data regardless of any security measures any service provider could possibly make, but that doesn't mean we should dismiss all such security measures.

remember Lavabit [0]? will Apple choose to shut down rather than to comply [1]? if the government comes with a warrant, it will be with a gag order, and they will be compelled to silently update your phone to extract whatever the govt needs over the course of a few months.

the details of exactly what they were disputing matters:

in this case it could have set a dangerous (and expensive) precedent for them.

that does not mean they will fight any and all requests.

What is your actual point here? It feels like we’re just playing a game if hypotheticals that are no longer based in reality.

Sure Apple could update your device to send all your photos unencrypted to them. They could also remotely turn on the mic and spy on all of us. They could also add key word detection to iMessage and flag law enforcement if you text out the wrong words.

I think everyone here understands what Apple could do. Which is why it’s a good thing that signs point to Apple not wanting their customer data. And why Apple refusing government orders that they feel violate their customers is unequivocally a good thing (even if they’re doing it for selfish reasons)

> What is your actual point here?

that e2e encryption by a third party does not give you privacy from the US government if that third party can remotely control or update your device and is subject to US laws. it is a direct reply to the assertion made in the GP: "The adversary is someone attacking the service provider, like a hacker or a government with a warrant, and getting access to Apple's storage of your data."

> will Apple choose to shut down rather than to comply

Apple will probably comply, just like I would probably comply rather than go to jail or suffer injury to myself or my loved ones. But I think it's fair to treat that as a distinct threat.

I disagree - the service provider should be considered an adversary and their service - and your tooling - should make it possible to obfuscate every single bit of data and metadata that you store there.

If only such a service existed.

If only …

rsync.net is great and I've always appreciated the exposed ZFS capability, even if at this point 3x the cost per gb for a small scale users vs B2 is a lot more painful. Having encryption, including for transfers, also be part of the filesystem (which is open source) is great. Pity but for a small turn of history ZFS didn't become the native FS for Apple. And I think backups in particular is one of the focused completely unambiguous areas where Apple really has behaved in textbook anticompetitive fashion, and they should be required to allow people to point their iOS devices at any 3rd party service (including their own!) they wish that implements the right API (which Apple should have to document and follow themselves).

Still with all that said:

>I disagree - the service provider should be considered an adversary and their service - and your tooling - should make it possible to obfuscate every single bit of data and metadata that you store there.

If you're using Apple devices at this point then I think they do unavoidably form some part of your core trust foundation. With current hardware Apple is everywhere in the stack right down to the CPU level, heck arguably below that since they have a special license with ARM and can implement their own custom extensions. If you really think they're an adversary to the point of doing custom backdoors explicitly going after you, then the hardware just can't be trusted.

It's not unreasonable though to look at both Apple's incentives and the state of American law at least and see distinctions between Apple being compelled (or hacked) to provide something they have passive access to on their side anyway vs being compelled to engage in non-consensual active work and feature development (or having that slipped in and make it into general deployment) on things that necessarily must go out to end user devices. The former is both bog standard warrant/subpoena territory and not inherently detectable outside of Apple and the government, since it doesn't directly involve the user as a party at all. The latter is very arguably illegal and provokes far more public response, and involves deploying in ways that make it far harder to keep concealed (and open up other avenues of challenge).

I don't get it. If you don't trust Apple, then you don't take photos with an iPhone. There is no possible service they could offer that assures you every bit of data and metadata is obfuscated end to end in any sense of before Apple software has a chance to see it. At bare minimum, the camera app has to put together a file before there is anything to encrypt. A malicious Apple could just keep a second copy of that file, and even if you used a different backup service, they'd still have it.

I've used such a service for at least a decade. End-to-end encrypted. All open source. ;)

Working on it. It's complicated ...

However, as with all things here, you can just email and discuss with a real person and we'll set you up the way you need to be set up wrt billing and pricing, etc.

Re:Apple introduces end-to-end encryption for backups by tshaddox on Wednesday December 07, 2022 @08:05PM (#33902749)
I think that's a separate issue. I'm not saying that Apple or any other service provider should not be considered a potential adversary. I'm saying it's still a good thing for service providers to implement solutions to threats.
Re:Apple introduces end-to-end encryption for backups by Terretta on Wednesday December 07, 2022 @03:56PM (#33900111)
We used to call this "NSL-proof". If your provider is architected to be NSL-proof, then the warrant has to get served to you.

This is now possible to achieve in AWS, for example.

Re:Apple introduces end-to-end encryption for backups by acdha on Thursday December 08, 2022 @09:02AM (#33907937)
I think the right way to advocate for this really is to focus on the warrant aspect. It’s not about preventing law enforcement but keeping it above board where there’s at least the possibility of oversight and targets can exercise their rights to things like legal representation.
