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. But a caveat: Nissan is also a huge company with massive budgets and they made an absolute mess of the security around their car. 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. Great deal of respect for your work on haveibeenpwned, but disappointed https://t.co/6HdBMYcOnO. Bottom of gateway is a key / QR that can be used to generate an access key. One popular approach is to isolate the network the IoT things are on from the network the non-IoT things are on. Published August 19, 2020.

Remember, the one with the security flaw which was patched and then broke the HA integration? 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. I ended up constantly debugging network traffic and searching across endless threads just like this one trying to work out why Sonos wasn't playing nice across VLANs. If what I tweet doesn't resonate with you, unfollow me. Thing is even when I'm bang on topic in terms of the content people expect from me - bang "on brand" as you'll see in a moment - people still get cranky: Dude, come on. @troyhunt. Read more about why I chose to use Ghost. I've been directly involved in the discovery or disclosure of a heap of these and indeed, security is normally the thing I most commonly write about. The second point is trickier because we're talking about a whole bunch of devices in the house running web servers and talking HTTP. This work is licensed under a Creative Commons Attribution 4.0 International License. In a perfect world, companies would approach this in the same way Shelly has: One company that we have partnered with is Shelly. For example, before the aforementioned TP-Link firmware update, HA could reach out from its home in my server cabinet directly to the smart plug in Ari's room and communicate with it over port 9999. ), but they would make a commitment to ensure their devices are "open" and accessible to other platforms in a documented, supported fashion that won't be broken by future patches. 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?" Let me include a screen grab of the poll NordVPN posted in that tweet because for reasons that will become apparent in a moment, your experience may differ: When I first saw this poll, it had already ended so the votes were on full display. But not everyone was happy with us being out enjoying the sunshine: What is this #ShowOff by the privileged tech leaders nowadays (@mitchellh, @troyhunt). Still want to be able to turn your lights on? Nov 9. Nov 9. Use devices you can drop Tasmota onto. It's painful.). And yes, I know times are tough in many places in the world right now and if that's what you'd like to focus on then by all means, seek out that content. 2. I often run private workshops around these, here's upcoming events I'll be at: Don't have Pluralsight already? Check your email, click the confirmation link I just sent you and we're done. 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. 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. Can you imagine your parents VLAN'ing their IoT things? This site runs entirely on Ghost and is made possible thanks to their kind support. 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. A good example of the importance of this brings me back to the TP-Link plugs I mentioned earlier. It also grants me more privacy as the devices aren't perpetually polling someone else's cloud... almost. Hide content and notifications from this user. (Sidenote: regarding this particular issue, it looks like work has been done to make HA play nice with the newer version of the firmware.). 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. 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. And what makes that desk "ergonomic"? Wondered what this was when i got the notification, cheers. 15. See traffic statistics for more information.. Yeah, she pretty much nailed it in terms of being "on brand" because investigating data breaches and writing about their aftermath is pretty much what I've carved out a name for myself doing! 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 . So, what's the right approach? What if it's one of those really slick high-DPI ones that gets really pricey? Opinions expressed here are my own and may not reflect those of people I work with, my mates, my wife, the kids etc. 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. 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. View Troy Huntâs profile on LinkedIn, the worldâs largest professional community. Ugh. When I set up version 2 of my UniFi network (complete tweet thread here), I kept the IoT SSID but never bothered with the VLAN. I find the sleight against self-promotion in particular a nonsensical position to take on a social media platform I use to amplify my messaging. 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. It's painful enough for me! I've had this blog post in draft for quite some time now, adding little bits to it as the opportunity presented itself. Probably “no”, but in a perfect world they’d document local connections by other apps and not break that. troyhunt (Troy Hunt) is now on Keybase, an open source app for encryption and cryptography. He's also done the same thing with his Pi-hole. @troyhunt. Increasingly, we're seeing IoT things support HTTPS which is great, and it goes a step further in taking us towards that zero trust principle, but it's not all that simple... Every Shelly I have in the house has its own little web server and I connect to it locally via IP address... over HTTP. 793 Followers, 23 Following, 77 Posts - See Instagram photos and videos from Troy Hunt (@troyhunt) 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. Running UniFi, I can easily create multiple Wi-Fi networks: As we then look at which clients have connected to which SSIDs, we can see them spread across the primary (HTTP403) and IoT (HTTP403 IoT) networks: I've also got a heap of access points across my house so different devices are connected to different APs depending on where they're located and what signal strength they have. 0. And finally, what's the impact if it does? Report or block troyhunt. In that perfect world, TP-Link wouldn't necessarily need to go as far as devoting resources to building HA integrations (although that would be nice! 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. So, you end up tracking down devices, ports and protocols and creating ever more complex firewall rules between networks. When we put this into the context of your average consumer, it means that stuff just needs to work out of the box. 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! See the complete profile on LinkedIn and â¦ 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. Have I Been Pwned's code base will be open sourced. Beautiful day out! In part 2, I covered IP addresses and the importance of a decent network to run all this stuff on, followed by Zigbee and the role of low power, low bandwidth devices. 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! As it relates to IoT, let's look at it in 2 different ways: The first point is a bit of a no brainer because all the certificate management is done centrally by, say, Amazon for their Echo devices. Speaking of trading problems, another approach is just to flash the devices with custom firmware like Tasmota: Moral of story, avoid anything requiring proprietary access. 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. 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.). Author: troyhunt Weekly Update 80. There's an easy answer: because it improves my life. I'd like everything to be sent over a secure transport layer (perhaps per Paulus' IKEA suggestion), and certainly any devices acting as clients communicating with external servers should be doing this already, but inevitably, there will be gaps. Join the Telegram channel In December 2019, the booking website Sonicbids suffered a data breach which they attributed to âa data privacy event involving our third-party cloud hosting servicesâ. If You Don't Want Guitar Lessons, Stop Following Me. The point here is that I'm effectively doing my own little risk assessment on each IoT device, and you can too. Troy has 4 jobs listed on their profile. â Troy Hunt (@troyhunt) November 23, 2020. 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. If you're not already using a password manager, go and download 1Password and change all your passwords to be strong and unique. Then use DTLs for encryption. Let's just take a slice out of out of the Wikipedia definition: It's become a bit of a buzzword of late but the principle is important: instead of assuming everything on the network is safe because you only put good things on the network, assume instead that everything is bad and that each client must protect itself from other clients. Using features such as Ubiquiti's privacy zones on their Protect cameras also helps: Those black boxes are recorded onto all video the camera captures and shield both the master bedroom and the pool from view should someone obtain the video. For some reason, the Shelly on my garage door is making a DNS request for api.shelly.cloud once every second! People just aren't going to do this themselves. There's also the added upside of the resiliency this brings with it should an IoT manufacturer have an outage on their cloud: for my gear that is Tuya based, Tasmota has been flawless for me. Yeah, me either, because most of mine are probably like yours: the simplest electrical devices in the house. 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! Our view of SSL or HTTPS or TLS (and all those terms get used a bit interchangeably), has really changed over the years. Here we had a situation where an attacker could easily control moving parts within a car from a remote location. Now for the big challenge - security. Troy Hunt retweeted. troyhunt / rick-roll-content-scraper.js Created Aug 19, 2020 A Cloudflare worker to redirect image requests from dickhead content scraper's site to a Rick Roll â Troy Hunt (@troyhunt) March 8, 2019 The reason I don't know if it makes it better or worse is that on the one hand, it's ridiculous that in a part of the world that's more privacy-focused than most it essentially boils down to "take this cookie or no access for you" whilst on the other hand, the Dutch DPA somehow thinks that this makes any sense to (almost) anyone: Nissan Leaf vulnerability someone in my workshop found almost 5 years ago now, TicTocTrack kids tracking watches which allowed a stranger on the other side of the world to talk to my 6 year old daughter, ) teddy bears that amounted to no auth on the Bluetooth allowing an attacker to take control of the toy, Lixil Satis toilets had a similar vulnerability due to hardcoded PINs on all "devices", my own story about kids' CloudPets messages being left exposed to the internet, then left it open to very simple vulnerabilities, the fix is to raise a support ticket with TP-Link, work has been done to make HA play nice with the newer version of the firmware, I've written many pieces before about Ubiquiti before, Ubiquiti has a good writeup of how to do this, just like this one trying to work out why Sonos wasn't playing nice across VLANs, Which? In other words, share generously but provide attribution. It's a constant frustration to see people behave in this fashion, where they pick something that I found interesting, put on it my timeline and because it's not appropriately curated to their personal desires, they sit down and have an angry keyboard rant.
