It also gives me the option to easily put it all on a different subnet later on, for example if I genuinely get to the point of IPV4 exhaustion on the 192.168.1.0/24 subnet. 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? By themselves? I like my IoT devices and in order to reap the benefits they provide, I'm willing to wear some risk. Block user. 793 Followers, 23 Following, 77 Posts - See Instagram photos and videos from Troy Hunt (@troyhunt) 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! Troy Hunt is a Microsoft MVP for Developer Security, ASPInsider, and Author for Pluralsightâa leader in online training for technology and creative professional Turns out you can't tell by looking at the device itself, you need to jump back out to the main menu, go down to settings, into firmware update then you see everything pending for all devices: I don't know how to auto-update these nor do I have any desire to continue returning to the app and checking what's pending. As @GerryD says further down that thread, it's a calculated risk and ultimately, you're trading one problem off against another one. In other words, one person's vulnerability is another person's integration . There are, however, some very practical, very common-sense things we can do right now to improve the security posture of our IoT things so let's finish up by talking about those. (The only exceptions are inside my garage and my boatshed, both places where nothing happens I wouldn't be comfortable with the public seeing.) 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. Let's look at one more related topic - TLS. In part 2 I talked about the importance of good networking gear and indeed I've written many pieces before about Ubiquiti before, both their AmpliFi consumer line and UniFi prosumer line, the latter having run in my house for the last 4 years. For example, just yesterday I thought it would be nice to take a boat ride and enjoy the impending summer weather down here: Gold Coast days pic.twitter.com/YUJIqgYNXf. Great deal of respect for your work on haveibeenpwned, but disappointed https://t.co/6HdBMYcOnO. We need to do better as an industry; better self-healing devices, better zero trust networks and better interoperability. did a review on smart plugs and found the following, Scott has written in the past about how to set up HTTPS on the UDM, He's also done the same thing with his Pi-hole, Stranger hacks into baby monitor, tells child, 'I love you', Suggesting you shouldn’t digitise your sexual exploits isn’t “victim blaming”, it’s common-sense, Ubiquiti's privacy zones on their Protect cameras, I'd just installed Ubiquiti's AmpliFi ALIEN unit at this friend's house, Data breach disclosure 101: How to succeed after you've failed, Data from connected CloudPets teddy bears leaked and ransomed, exposing kids' voice messages, When a nation is hacked: Understanding the ginormous Philippines data breach, How I optimised my life to make my job redundant, OWASP Top 10 Web Application Security Risks for ASP.NET, What Every Developer Must Know About HTTPS, Hack Yourself First: How to go on the Cyber-Offense, Modernizing Your Websites with Azure Platform as a Service, Web Security and the OWASP Top 10: The Big Picture, Ethical Hacking: Hacking Web Applications, Creative Commons Attribution 4.0 International License, Risks that impact data collected by IoT devices, Risks that impact IoT devices due to vulnerabilities in web APIs, Risks that impact IoT devices due to vulnerabilities in the device itself, Devices talking to hosted services over HTTPS. I've chosen to place all my highly trusted devices such as my iPhone, iPad and PCs on the primary network and all the IoT things on the IoT network. 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. I've had this blog post in draft for quite some time now, adding little bits to it as the opportunity presented itself. People just aren't going to do this themselves. Now, there's one reason and one reason only why I tweeted about the car and I'll summarise it succinctly here: This is not a hard concept to grasp: I post things to my feed I get pleasure from and this person grumbling about "I don't fucking like cars" has absolutely zero impact on my propensity to post more cars in the future (I've posted a lot of car tweets since then). @troyhunt. 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? Nov 9. @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 ⦠However, I also have a high degree of confidence that Tasmota is software, all software has bugs (open source or not), and you still need a patching mechanism. Ok, guess you could just ignore them then, would that work? Let's got through the options: I'll start with the devices themselves and pose a question to you: can you remember the last time you patched the firmware in your light globes? And finally, what's the impact if it does? We need to think differently. 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. For some reason, the Shelly on my garage door is making a DNS request for api.shelly.cloud once every second! What this means in practical terms is that HA can operate in a self-contained fashion within the local network. troyhunt (Troy Hunt) is now on Keybase, an open source app for encryption and cryptography. James Meikle @JamesMeikle. I had to manually enabled automatic updates and I had to do it on a per-device basis. Looks like @tplinkuk broke it with a firmware update which will now break a bunch of stuff around the house. So, what's to be done about it? Because people often ask if I trust them given I have one in each kids' room. 15. What upside does it bring you? We have pandemic and people stuggeling for existence, climate crisis threatening our kids future and we are all about planes, boats and huge houses. 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. 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. Whilst the underlying risk that exposes the data may well be a classic lack of auth CloudPets style, there'd be no data to expose were it not for adding internet to devices that never had it before. The back story to this was that I'd just installed Ubiquiti's AmpliFi ALIEN unit at this friend's house and in doing so, set up a brand new network with new SSID and subsequently set about migrating all the connected things to the new one. How likely is that to happen? If You Don't Want Guitar Lessons, Stop Following Me. By K. Holt, 08.07.2020. What downside does it present? Hide content and notifications from this user. If you're not already using a password manager, go and download 1Password and change all your passwords to be strong and unique. An adversary sitting at the network routing level (i.e. Oh yeah, apparently that's not on either: Skimming through the last week of Troy's posts I only see pictures of food, beer, and self promotionSomeone with an audience his size should be using it to help and amplify more important people and issues. As with the rest of the IoT landscape, there's a lot of scope for improvement here and also just like the other IoT posts, it gets very complex for normal people very quickly. Learn more about reporting abuse. Or are they just the same old risks we've always had with data stored on the internet? But this is just segmentation by SSID; every device is on the same subnet and the same logical VLAN and there's not presently any segmentation of clients such that the Shelly controlling the lights on my fireplace can't see my iPhone. But someone not wanting to see the joy in other people's lives and then berating them for sharing it is just plain stupid. 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. Can you imagine - with any of those 3 examples - your non-tech friends consciously thinking about firmware updates? I honestly don't know because it's not clear if, to use my earlier term again, they're self-healing. ocado @Ocado. See the complete profile on LinkedIn and ⦠A weather station is a sizable outlay compared to a smart plug and I don't want to go into it with an expectation of it working a certain way and then one day having that broken. You can find similar websites and websites using the same design template.. Troyhunt.com has an estimated worth of 86,531 USD. He created Have I Been Pwned?, a data breach search website that allows non-technical users to see if their personal information has been compromised. 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. (Sidenote: regarding this particular issue, it looks like work has been done to make HA play nice with the newer version of the firmware.). Be selective with what you connect: This whole journey began with me trying to automate my garage door, which I eventually did. â Troy Hunt (@troyhunt) November 23, 2020. 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. It's akin to moving away from the old thinking that all the bad stuff was outside the network perimeter and all the good stuff was inside. But a caveat: Nissan is also a huge company with massive budgets and they made an absolute mess of the security around their car. Stefán Jökull Sigurðarson - CCP Ghostrider @stebets. You want to draw attention to falsehoods help us, point out white nationalists being the perpetrators behind looting. TroyHunt; by admin. Now that's a binary question with a non-binary response because trust is not as simple as "completely" or "not at all", it's much more nuanced. 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. Troy Hunt retweeted. Troy Hunt. And before anyone starts jumping up and down suggesting that devices shouldn't auto-update because you should carefully test any patches before rolling out to production and ensuring you have a robust rollback strategy, these are consumer devices made for people like my mum and dad! 0. If you know the email, thatâs one factor and if you know the password, weâll, thatâs obviously another factor . Come find out To the best of my knowledge, most consumer-focused network products won't and why would they? Here's what I'm getting at with all this and I'll hark back to the title of part 1: it's a mess. Report abuse View GitHub Profile Sort: Recently created. Replying to @troyhunt @home_assistant Then you said someone named âHomer Simpsonâ has joined the chat.. ok something isnât right⦠ohhhh ð¡ Was a really good discussion last night, eventually had to drop around 2am MT. This tweet is exemplary behaviour by Shelly and if I'm honest, my opinion of them raised a few bars after reading this. See traffic statistics for more information.. A good example of the importance of this brings me back to the TP-Link plugs I mentioned earlier. So, you end up tracking down devices, ports and protocols and creating ever more complex firewall rules between networks. In part 1 of this series, I posited that the IoT landscape is an absolute mess but Home Assistant (HA) does an admirable job of tying it all together. 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. Nov 2. Don't think this is just a pandemic era phenomenon though; when I bought a new car a few years ago, I was excited and as such, I shared that excitement online: Is there a way to filter that kind of bullsh*t and stick to security/data-breach content _exclusively_ ? Beyond not so subtly expressing that he doesn't fucking like big monitors, Hakim doesn't really make it clear what can be shown without hurting his feelings. Easy . Learn more about blocking users. But also (and based on the TP-Link experience above), which ones have an integration that won't break in the future? Troubleshooting was painful; every time I had an IoT device not behaving as expected, I'd look suspiciously at the firewall rules between the VLANs. Opinions expressed here are my own and may not reflect those of people I work with, my mates, my wife, the kids etc. Ugh. How often would you think about firmware updates? Ricky Gervais does an amazing job of explaining what I'm about to delve into so do yourself a favour and spend a minute watching this first: And therein lies the inspiration for the title of this blog. 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? 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! Main thing is support for a chime box inside the house (also required) plus the usual video and audio to mobile devices. troyhunt writes: It seems that Apple, as part of their demo and support processes, are connecting new Macs and iOS devices to an in-store Wi-Fi network without any encryption.Whilst not necessarily transferring any sensitive data at the time, the devices have been found to then willingly connect to rogue access points such as a Wi-Fi Pineapple as soon as they leave the store. Same again with the TicTocTrack kids tracking watches which allowed a stranger on the other side of the world to talk to my 6 year old daughter. Dec 4. The integration is maturing fast and next release will be really . There's a wall around the house behind those green palms, but it can be jumped. 0. The thing with both the car and the watch hacks though is that the vulnerability was at the API layer, not the device itself and this is where we spear off into another 2 directions: I've given 2 examples of the first point, so here's 2 examples of the second beginning with LIFX light bulbs. Domain Name: troyhunt.com Registry Domain ID: 13201270_DOMAIN_COM-VRSN Registrar WHOIS Server: WHOIS.ENOM.COM Registrar ⦠The personal NAS shouldn't be wide open to a connected sous vide turned rogue. What if it's one of those really slick high-DPI ones that gets really pricey? Just one screen? Hope I'm not just jeolous or the Twitter AI. 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. That data is from my Pi-hole and the Shelly is configured precisely per the earlier image. In fact, most websites didn't have it but these days, it's quite the opposite; most websites do serve their traffic securely regardless of the type of business they are. It made it easy for all the existing devices to jump onto the new network (I used the same password from the v1 network) and it gives me the option to segment traffic later on. 0. When we put this into the context of your average consumer, it means that stuff just needs to work out of the box. I know Troy isn't fond of the firmware replacement approach, but I don't want to wake up one day (or not wake up!) I can't blame this on the teddy bears themselves, rather the fact that the MongoDB holding all the collected data was left publicly facing without a password.
