This allows us to understand, and potentially modify, how it works.

When man-in-the-middle-ing a device, we intercept and inspect the online traffic that goes in and out of it. However, in order to be used against internet of things (IOT) devices, it requires some creative adaptation. This technique, which we will discuss in more detail below, is most commonly used in order to snoop on the network activity of smartphone apps. In order to probe the Snoo’s behavior, I had to attempt a man-in-the-middle attack against it. We’ll learn a lot about TLS, DNS, TCP, and make a lot of beautiful stories to tell our grandchildren along the way. In this post we will look at how I was able to find this bug, and how you can use the same techniques to examine the behavior of your own IOT devices, be they cribs, fridges, lightbulbs, or exercise bikes. They were very pleasant and responsive, and told me they would fix it in their next firmware update. I sent an email to the Snoo team describing the bug. Whilst this is certainly a problem, I couldn’t immediately see any way to convert this toehold into something that would materially help me with any of my villainous plans. I didn’t find any particularly heinous vulnerabilities, but I did find a small protocol downgrade bug, which allowed me to force the Snoo to send some of its status data over unencrypted HTTP instead of HTTPS.

I went in search of security flaws in the crib that would allow me to take control of it and use it for my various nefarious schemes. Nonetheless, I figured that if the Snoo people were going to make their crib wi-fi enabled then I might as well have some fun when Oscar wasn’t using it. Perhaps there’s a use-case that I’m missing. I do feel like I’m from the future when I show my parents how I can wobble my baby using only my phone, but it’s a future where no one has given much thought to exactly why the future is better than the past. I’d much prefer it if they ditched the whole internet-of-things angle and just gave me some buttons that I can press with my real-world fingers and that don’t stop working when my wi-fi goes down. If it hears him getting grumpy, it ratchets up the speed and the volume to try to make him happy again.įor some reason, you have to control the Snoo from a smartphone app. A Snoo is a smart-crib that rocks your baby to sleep and plays him soothing white noise. Rave reviews and hopeful optimism outweighed our natural skepticism, and we rented him a Snoo.
