Reading through the responses to my original question, the resounding feedback was that when it comes to IoT communicating inside home networks, people weren't too concerned about a lack of transport layer encryption. One approach is that rather than trying to integrate directly between the weather station and HA, you find a weather station that can integrate with Weather Underground (which Davis can do with WeatherLink Live) then use the Weather Underground integration. What if it's one of those really slick high-DPI ones that gets really pricey? Replying to @troyhunt. Fortunately, that didn't include driving functions, but it did include the ability to remotely manage the climate control and as you can see in the video embedded in that post, I warmed things up for my mate Scott Helme from the other side of the world whilst he sat there on a cold, damp, English night. Replying to @troyhunt @home_assistant Then you said someone named “Homer Simpson” has joined the chat.. ok something isn’t right… ohhhh 💡 Was a really good discussion last night, eventually had to drop around 2am MT. The WoT scorecard provides crowdsourced online ratings & reviews for troyhunt.com regarding its safety and security. So, what's to be done about it? Still want to be able to turn your lights on? Domain Name: troyhunt.com Registry Domain ID: 13201270_DOMAIN_COM-VRSN Registrar WHOIS Server: WHOIS.ENOM.COM Registrar … (And yes, fellow techies, that's a sizeable amount more than a 32-bit integer can hold .) Good news — no pwnage found! And, just like the LIFX devices, they're going to need patching occasionally. When we put this into the context of your average consumer, it means that stuff just needs to work out of the box. Nov 2. But rightly or wrongly, the risk you take when using devices in a fashion they weren't designed for is that the manufacturer may break that functionality at some time. See the complete profile on LinkedIn and … I've also placed the Ubiquiti cameras (including their doorbell) on the primary network figuring they're all essentially part of the UniFi ecosystem anyway. He has also authored several popular security-related courses on Pluralsight, and regularly presents keynotes and workshops on security topics. My worst-case scenario if my cameras are pwned isn't the exposure of my kids to strangers or an intimate moment with my partner, it's only publicly observable activity. Same with the Shellys I've become so dependent on: And just to perfectly illustrate the problem, I snapped that screen cap the day before posting this part of the series. Every time one of the kids asks Alexa a question, a TLS connection is established to Amazon's services and they get the benefit of confidentiality, integrity and authenticity. I mean you should see how many pics I post of beer! Another example also from Context Security was the vulnerability in CloudPets talking (and listening) teddy bears that amounted to no auth on the Bluetooth allowing an attacker to take control of the toy. 0. I like my IoT devices and in order to reap the benefits they provide, I'm willing to wear some risk. Well this is different; a weekly update bereft of neon studio lighting and instead done from the great outdoors, complete with all sorts of animal noises and a (probably) drunk green tree frog. In a perfect world, companies would approach this in the same way Shelly has: One company that we have partnered with is Shelly. Authlogics Password Security Management ensures Active Directory password compliance with NIST SP 800-63B and that they haven't been breached online. Adult toys have been around forever and a day, they're not new, but recording their usage and storing it on the cloud is a whole different story. The point in all these cases isn't to say someone is "wrong" for using a connected baby monitor or making kinky home movies, rather that doing so increases the chances of an otherwise private event being seen by others. I mean, seriously now... (Side note: I talked about this particular tweets in my Hack Your Career talk at NDC Oslo a few years ago, deep-linked just to the right spot for your viewing convenience.). It's not. I've even pulled the JSON from the /settings API on the Shelly (you can hit that path on the IP of any Shelly on the network and retrieve all the config data), diffed it with other Shellys not displaying this behaviour and I still can't work out why it's so chatty. There's a lot to be said about local control. But Jennifer doesn't fucking care about disinformation campaigns stemming from data breaches designed to influence public sentiment, and she damn well wants me to know that. We have pandemic and people stuggeling for existence, climate crisis threatening our kids future and we are all about planes, boats and huge houses. Learn more about reporting abuse. Wouldn't want a dint in that nice shiny car car now would we. Unless I'm quoting someone, they're just my own views. There will be those who respond to this blog post with responses along the lines of "well, you really don't need any of these things connected anyway, why take the risk?" Nov 9. If You Don't Want Guitar Lessons, Stop Following Me. Let me break this down into logical parts and use real world examples of where things have gone wrong and I'd like to cover it in two different ways: Let's take that first point and what immediately came to mind was the Nissan Leaf vulnerability someone in my workshop found almost 5 years ago now. How often would you think about firmware updates? The requirement for doing this is to have networking gear in the home that supports it. An adversary sitting at the network routing level (i.e. Looks like @tplinkuk broke it with a firmware update which will now break a bunch of stuff around the house. What downside does it present? Troy has 4 jobs listed on their profile. He's also done the same thing with his Pi-hole. I started with the Philips Hue app which was both auto-updating and at the latest firmware version: Ok, that's good, not something I need to think about then. It also grants me more privacy as the devices aren't perpetually polling someone else's cloud... almost. 0. Let's try Nanoleaf which are the LED light panels both kids have on their walls: Ok, so they're up to date, but will they stay up to date? The main problem is that you end up with all sorts of scenarios where a particular IoT device needs to see the app that controls it but because the very purpose of the VLAN is to lock the IoT things away, things would fail. Use devices you can drop Tasmota onto. Have I Been Pwned's code base will be open sourced. — Troy Hunt (@troyhunt) October 24, 2020. Then use DTLs for encryption. Security goes well beyond just digital controls, indeed there are many ways we can influence our IoT security posture simply by adjusting the way we think about the devices. 2. The key term in that sentence is "my timeline" and as most of this relates to Twitter, there's a very easy way to understand whose timeline you're looking at: This is me, talking about the things that I find interesting. I've not connected that door as it presents a greater risk and provides less upside if connected than the external door thus is harder to justify being IoT enabled. (Sidenote: even this can be painful as the native apps for many IoT devices want to join them to the same SSID the phone running the app is on so I found myself continually joining my iPhone to the IoT SSID before pairing... then forgetting I'd done that and later wondering why my phone was on the IoT network! This password wasn't found in any of the Pwned Passwords loaded into Have I Been Pwned. It's painful.). If we recognise this whole thing is a mess and that at least as of today, we don't have a good strategy for keeping things patched, what should we do? Come find out What I know about each of the multi-billion dollar tech companies mentioned here is that they have huge budgets for this stuff and are the most likely not just to get it right in the first place, but to deal with it responsibly if they get it wrong. Ok, so the joke is a stupid oldie, but a hard truth lies within it: there have been some shocking instances of security lapses in IoT devices. 0. That data is from my Pi-hole and the Shelly is configured precisely per the earlier image. Sort options. GitHub Gist: star and fork troyhunt's gists by creating an account on GitHub. Can you imagine - with any of those 3 examples - your non-tech friends consciously thinking about firmware updates? They can always screw you. Right about now, a small subset of my readership is getting ready to leave angry comments about "victim blaming" and I'll ask them to start with a blog post from almost 5 years ago titled Suggesting you shouldn’t digitise your sexual exploits isn’t “victim blaming”, it’s common-sense. In the final part of this series I'm going to do video walkthroughs of a whole bunch of different ways in which I benefit from my connected environment, showing how each connected thing operates. 4 Mar 2019. Never mind the fact it's 11 years old and worth nothing and besides, while we're talking about fancy devices: So many people in the world could not afford the pocket-sized supercomputer you tweeted that from, but that doesn't seem to bother you, It does make me chuckle just a little to see all the likes on that tweet . Great deal of respect for your work on haveibeenpwned, but disappointed https://t.co/6HdBMYcOnO. Finally, and per the last couple of blogs in the series, Scott and I will be talking live about all things IoT (and definitely drilling much deeper into the security piece given the way both of us make a living), later this week via this scheduled broadcast , Hi, I'm Troy Hunt, I write this blog, create courses for Pluralsight and am a Microsoft Regional Director and MVP who travels the world speaking at events and training technology professionals, Hi, I'm Troy Hunt, I write this blog, run "Have I Been Pwned" and am a Microsoft Regional Director and MVP who travels the world speaking at events and training technology professionals. This tweet is exemplary behaviour by Shelly and if I'm honest, my opinion of them raised a few bars after reading this. Does it need an update? More specifically, they closed off the port that allowed HA to talk directly to the smart plug which broke the integration, but didn't break the native Kasa app. How about a 10 day free trial? Read more about why I chose to use Ghost. Just over a day later, it's a different story and I only knew there was an update pending because I fired up the app and looked at the device: I checked just one of the couple of dozen connected lights running in the Tuya app: This looks good, but it wasn't the default state! I often run private workshops around these, here's upcoming events I'll be at: Don't have Pluralsight already? Somewhat ironically though, I suspect that whilst on the one hand the TP-Link situation is viewed as a vulnerability, the ability to connect directly to it on the local network is probably what made the HA integration feasible in the first place! This site runs entirely on Ghost and is made possible thanks to their kind support. Because people often ask if I trust them given I have one in each kids' room. Beyond a cursory Google search that returned no results, I haven't even begun to think about the logistics of installing a cert on a Shelly let alone the dozen other Shelly devices I have in the house. It's fiddly, time consuming, fraught with problems and most importantly, completely out of reach for the huge majority of people using IoT devices. 793 Followers, 23 Following, 77 Posts - See Instagram photos and videos from Troy Hunt (@troyhunt) For the rest of us, we need to recognise that we take on risks when using IoT devices in ways they weren't designed for. This is super important because your average person simply isn't going to manually patch their light bulbs. He regularly blogs about application security, improving the software development process and all things technology related at troyhunt.com. Join the Telegram channel In December 2019, the booking website Sonicbids suffered a data breach which they attributed to “a data privacy event involving our third-party cloud hosting services”. So, you end up tracking down devices, ports and protocols and creating ever more complex firewall rules between networks. That resiliency extends beyond just a cloud outage too; what if Tuya shuts down the service? This mindset is akin to putting all the potentially bad eggs in the one basket and the good eggs (such as your PC) in another basket. The second point is trickier because we're talking about a whole bunch of devices in the house running web servers and talking HTTP. I'm Troy Hunt, an Australian Microsoft Regional Director and Microsoft Most Valuable Professional for Developer Security. @troyhunt. The personal NAS shouldn't be wide open to a connected sous vide turned rogue. And what makes that desk "ergonomic"? Some of them, however, are more like the LIFX example from before in that they have little microprocessors and are Wi-Fi (or Zigbee) enabled. That door is internet connected and it allows me to remotely open it so couriers can drop off packages or I can easily ride my bike back inside the property boundary (I just ask Siri on my watch to open it up). Troy Hunt is a Microsoft MVP for Developer Security, ASPInsider, and Author for Pluralsight„a leader in online training for technology and creative professional What this means in practical terms is that HA can operate in a self-contained fashion within the local network. 0. That'll get you access to thousands of courses amongst which are dozens of my own including: Hey, just quickly confirm you're not a robot: Got it! But a caveat: Nissan is also a huge company with massive budgets and they made an absolute mess of the security around their car. @troyhunt 27 Apr I've just installed #covidsafe and want to capture my thoughts on the experience and the general principles behind the app here, especially as … Just blogged: If You Don't Want Guitar Lessons, Stop Following Me troy.hn/3mKOLdz. 3. There's no consistency across manufacturers or devices either in terms of defaulting to auto-updates or even where to find updates. Now you've introduced another risk because you're not taking patches and you have to trade that off against the risk you run when you do take patches! ocado @Ocado. I got an email from hibps saying it's been pwned and I want my email removing from your system or else I might have to take drastic action. The point I'm making here is that devices can do a lot of communicating back to the mothership and where possible, this should be disabled. The vulnerability Context Security discovered meant exposing the Wi-Fi credentials of the network the device was attached to, which is significant because it demonstrates that IoT vulnerabilities can put other devices on the network at risk as well. How about a 10 day free trial? @troyhunt. But also (and based on the TP-Link experience above), which ones have an integration that won't break in the future? (Sidenote: regarding this particular issue, it looks like work has been done to make HA play nice with the newer version of the firmware.). Neither is encrypted.I think the way IKEA does CoAP is neat. Author: troyhunt Weekly Update 80. 1. Perhaps that's just a matter of time and as demand grows, who knows, we might even see HA on the TP-Link box alongside the tech behemoths. What appears to have happened is that in order to address "security vulnerabilities on the plug", TP-Link issued a … I hit the update button and assumed all would be fine... (it wasn't, but I'll come back to shortly). If what I tweet doesn't resonate with you, unfollow me. I'm looking around at devices (the Davis Vantage Pro2 is the frontrunner at present, but I'm open to suggestions), and that then raises the question: which ones have an integration with HA? His comedy skit nailed it too: my Twitter timeline is literally just me talking about the things I'm interested in and whilst that might be predominantly technology and infosec stuff, turns out I actually have a life beyond that too.
