Three ways to hack… a mattress!

A security researcher has investigated his own smart mattress cover, discovering several ways to hack it — including through a backdoor preinstalled by the developer.
 
For a while after we wrote about hacking a bicycle, it seemed it couldn’t be beat as the most unlikely hack target ever. However, developers’ imagination seems to know no bounds — and hackers aren’t far behind in their ingenuity…

And so, here’s introducing the internet-connected mattress system — or “Pod” as it’s called — made by the company Eight Sleep, along with several ways it can be hacked as discovered by security researcher Dylan Ayrey.

Smart mattress Pod? What’s that?

Perhaps we should start by explaining what an Eight Sleep Pod is and why someone might want to buy this futuristic piece of tech. The Eight Sleep designers position their product as an “Intelligent Bed Cooling System”. The primary target audience is people with various sleep problems: insomnia, poor sleep quality, snoring, and similar issues that can significantly impact quality of life.

The Pod is made up of a sheet-like “high-tech layer” (“Cover”), and an external unit (“Hub”); optionally there’s also a motorized “Base”. It allows users to adjust the temperature of the bed — heating it up or cooling it down as instructed by the owner. It can do it automatically too — more on this later. There’s a network of tubes with water circulating through them built into it. The external unit connected to this system handles the heating and cooling. The Eight Sleep Pod is divided into two independent zones of a double-bed — each with its own settings. The temperature range is fairly broad: from 12 to 43°C.

But wait: there’s more to it! The Pod has several dozen “clinical-grade sensors” that track users’ sleep quality. It also has vibration motors to wake you up, and sensors for ambient temperature and humidity. The ultimate version — the Pod 4 Ultra — comes with a transformable, electronically-controlled bed base.

It goes without saying that the system connects to the internet. It does this via a Wi-Fi receiver in the Hub. Eight Sleep Pods are configured and controlled almost exclusively via an app. We say “almost”, because the latest (and most expensive) generation — Pod 4 — has pressure-sensitive areas on the sides that you can tap to control certain functions.
