This is fucked up, but it’s still somehow better than a Murphy Bed backdoor.

Great article, with a pretty cool (or warm) solution to the problem.

Trying very hard not to come to the conclusion that if you waste 2000 bucks on a connected bed, you have only yourself to blame.

Seriously. Unlike dumb TVs, dumb beds are not going away. Buy one for 400 bucks and donate the remainder of your bed-buying fortune. Your body won’t notice and €1600 can do a lot of good.

When you blame consumers for allowing antisocial tech into their lives, you’re doing free work for the tech barons.

JubilantJaguar@lemmy.world on 22 Feb 18:44 collapse

So nobody has any agency and we’re all just helpless puppets on strings?

kibiz0r@midwest.social on 22 Feb 19:24 collapse

On the contrary. I want people to have their own opinions, and to buy the things that suit their tastes even if they seem silly to me.

And I want those things to have fair, consumer-friendly regulations applied to them.

And when companies try to abuse their consumers, and I want us to criticize the company rather than the consumer.

I can get on board with that.

As a regular traveler I have slept in a lot of beds. Maybe 300 (sic) in the last decade, of all quality levels. For me it makes all but no difference to how much sleep I get, the only thing that bothers me is when the springs are literally sticking out. So this is all completely anecdotal and I do respect your own anecdote. But I can’t help noticing that I see it repeated in lots of bed adverts.

How old are you? Once you reach middle-age shit starts breaking, even if you’re fit which most of us aren’t. You’ll notice a good bed at forty much more than you will at twenty. By sixty you’ll be demanding one.

My partner and I have a basic box spring and a Queen-sized free mattress (from a family member.)

We put a 4” thicc memory foam topper on it and I can easily get 13 hours straight of sleep. It’s horrifying.

Hahaha nahhh I have a spouse I’ve been with forever and we’re never having kids, so we can sleep as much as we want to. I don’t get 13 hours EVERY day, but occasionally we get fucked up on various substances and need a long day of hibernation afterwards. Last night we got about four hours (special occasion party time!) so tonight we’ll probably get 10+ hours of sleep.

I’ve read some people get help from the cooling these provide, but I think there’s versions without subscriptions.

Also I’ve read of people buying shit like this in the hope it helps intractable insomnia, and they probably aren’t thinking that clearly, because of sleep deprivation.

JubilantJaguar@lemmy.world on 22 Feb 19:04 collapse

I share your suspicions but I’d go further. The bed industry has always struck me as an obvious scam that plays on people’s nebulous health anxieties and also on the tempting cognitive fallacy that, since an 8-hour night is the same amount as an 8-hour workday, the exact physical makeup of your bed is somehow as important as your career or something. It all strikes me as almost completely irrational. People slept for aeons on straw and somehow survived. A bed is a soft flat object, any other abstract properties are just marketing IMO.

queermunist@lemmy.ml on 22 Feb 19:43 collapse

Also, eight hours is a modern invention! Throughout most of human history we slept several times a day, rather than just once.

I’m really liking siestas these days and can’t go back to a single eight hour block.

JubilantJaguar@lemmy.world on 22 Feb 19:51 collapse

Absolutely. The 8-hour sleep is probably just a marketing invention, related to modern electric light. In pre-modern Europe it was common to get up and do housework in the middle of the night.

To be fair it’s more of a mattress than a bed

If the protocol was documented and simple enough, and if you could make it talk to your smart home RPi, then one could replace AWS with nginx + a perl or lua module.

I want to learn more about this! Searching for "bed backdoor " right now

CosmicGiraffe@lemmy.world on 22 Feb 12:15 next collapse

The email address attached to the public key, eng@eightsleep.com, to me suggests the private key is likely accessible to the entire engineering team.

This assumption is doing a lot of heavy lifting in the authors argument that this is a big deal.

Evotech@lemmy.world on 22 Feb 19:06 next collapse

How so, it’s clearly a shared account

I don’t think that’s a wild assumption to make

CosmicGiraffe@lemmy.world on 22 Feb 19:33 collapse

A shared account doesn’t mean everyone who works there has access to it, or that those who do have access aren’t subject to some type of access control.

The article basically goes on to say that the existence of this key makes a huge difference to the security/privacy of the product. It argues that using it, someone could access data from the device, or use it to upload arbitrary code to the device for it to run. However, those are both things the user is already trusting the company with. They have to trust that the company has access controls/policies to prevent individual rogue employees doing the things described. It seems unreasonable to say that an SSH key being on the device demonstrates that those controls aren’t in place.

Evotech@lemmy.world on 23 Feb 07:21 collapse

I agree to an extent, the user already uses a cloud service. So they have to trust the provider.

And as far as a bed goes, I suppose you can’t expect the customer to ssh into it if something goes wrong and you have to fix it.

Both seems reasonable to me.

CosmicGiraffe@lemmy.world on 23 Feb 09:56 collapse

Yeah, its not unreasonable that you’d have a remote way to access the device to gather debug data with the customers consent. An SSH key in the firmware is a flexible way to do that, so long as there are good controls in place to ensure that it isn’t misused.

AtariDump@lemmy.world on 22 Feb 21:28 collapse

Remember, the “s” in IoT stands for “security”.

I could completely see this email address being a shared email address and not tied to a single user.

CosmicGiraffe@lemmy.world on 22 Feb 22:28 collapse

I’m 90% sure it is not a single user. I just don’t see how that really affects the security of the product, given that the company that sells it can already do the things the author is saying can be done if you have this key.

To be clear, I wouldn’t buy this. I just don’t think the SSH key makes it any worse than it already was

AtariDump@lemmy.world on 23 Feb 04:35 collapse

Would you rather one person have access to your device / data to potentially perform malicious actions or multiple people access to your device / data to potentially perform malicious actions?

And if you tell me multiple people, you’re full of it.

CosmicGiraffe@lemmy.world on 23 Feb 09:52 collapse

I think multiple people already have access to the databases that store the data the device sends. I don’t really care whether they get the data from the device itself or from the database.

Similarly, I think multiple people have the ability to make changes to the firmware build and the systems that distribute it. So those people already have the potential ability to gain access to the device.

One person or multiple people having unauthorised access are both unacceptable. I’m saying that the users have to trust the companies ability to prevent that occurring, and that therefore this particular technical detail is mostly irrelevant

parpol@programming.dev on 22 Feb 12:55 next collapse

I was willing to overlook:

  • The bed costs $2,000
  • It won’t function if the internet goes down
  • Basic features are behind an additional $19/mo subscription
  • The bed’s only controls are via mobile app

My man would have been willing to overlook having Jeff bezos himself sleep in his bed with him before realizing what was happening.
