Toothbrushes gone wild!

3 million smart toothbrushes were just used in a DDoS attack. Really

What’s next, malware-infected dental floss? But seriously: It’s a reminder that even the smallest smart home devices can be a threat. Here’s how to protect yourself.

It sounds more like science fiction than reality, but Swiss newspaper Aargauer Zeitung reports that approximately three million smart toothbrushes were hijacked by hackers to launch a Distributed Denial of Service (DDoS) attack. These innocuous bathroom gadgets — transformed into soldiers in a botnet army — knocked out a Swiss company for several hours, costing millions of euros in damages.

No, we’re not kidding.

Have you heard about the toothbrushes gone wild before?
What appliances do you own that are considered smart?

  1. What a crazy story about the toothbrushes! As for smart devices, we don’t have any!! Dr. Zeus is very privacy- and security conscious, so presents a very compelling counterargument for every fun gadget out there. Our phones and computers run on open-source Linux operating systems, so he has full admin control. On vacation, he spent an hour disabling all the smart features on the rental car. Our good friend works in the field of AI and is similarly wary of smart devices, which I find to be very interesting.

    • I am not that tech savvy like you and Dr. Zeus. I’m not sure what we have that is “smart.” I have read that people who work in Silicon Valley won’t allow their children any devices and only let them play board games and in parks.

      • I don’t even know what all the devices are beyond Alexa/Echo (I don’t know what they are, really…), Ring doorbell, video baby monitors, robot vacuums, TVs, and refrigerators. I’ve been shown examples of all these things being hacked. Apparently, people hack baby monitors and sell access, so people can pay a few bucks to watch babies sleep or a woman breastfeeding… horrific!! Our friend in AI used to work in Silicon Valley and while they don’t yet have kids, they’re 100% doing no tech beyond what was available during their childhood (80s-90s).

  2. Nothing smart here, unless I am unaware and my wall heaters are listening in or transmitting! Your floss is part of the newest trend in dental floss. Stretchy and expanding. Almost every well-known dental brand has some form of this floss. My office is big on Coco Floss- same principle but it also has a bit of coconut oil which is good for tissues. I really want to know why anyone would need their toothbrush to be that connected that it could be hacked??

    Okay I just googled. The only thing a “smart” brush does is keep track of how you brush- analysis of time, pressure, technique basically- which I’m sure then can give you and your dentist some sort of real time data. What a ridiculous waste of resources and money!

    • I know my daughter uses a smart toothbrush. It does seem silly. The company even mails her a new head periodically which is more money. I don’t think we have smart appliances, but I’m not sure because they came with the house.

      • Actually, after I sent this comment I realized my stove has smart capabilities. My original died and the landlords replaced it with this high tech one, which I think was over the top… I have no idea how to even set up the expanded features and wouldn’t even if I did. I just want it to cook my food not monitor everything I do in the kitchen 😉

      • I’m not sure what a stove would do with smart capabilities? When we bought our house, the prior owners replaced some of the appliances, so they could be smart, too.

      • I suspect that it has to do much the same as the toothbrush. Monitor performance and such and be able to send reports to the owner. I have never sought to find the instructions on how to enable those features however.

      • I’m not going to bother with that either. We do have one smart appliance that I bought. It’s called Chef IQ. It looks like a crock pot but has an app on my phone. You put in the ingredients, it weighs them and cooks the right amount of time. It sears, is a pressure cooker and a slow cooker.

      • The one that really makes me shake my head is the fridge that tracks what you have and how much then alerts when things are low and makes a shopping list. I might be making this part up but I think it might also order groceries as well?? Regardless, I want none of it 😉

  3. Oh, that’s funny! I wish they would hack into my Convection Oven to cook my food without burning it. Better yet, just cook food when I think of it. Make the ingredients appear out of thin air. The ideas are endless…

  4. The iPhone, of course. A Google clock. My new bird feeder. My truck. My new headphones (apparently – it has an app for my phone). The TV and DVD player. The computers. All these things are connected to the internet is one way or another, though sometimes it’s just through the Bluetooth in my phone. None of our kitchen appliances, thank you. I don’t need my fridge telling what to buy at the store!
    My toothbrush is a GUM 524. It is the best toothbrush ever! It practically takes care of the flossing while I brush.

  5. On your recommendation I bought some of Dr. Tung’s smart floss and love it. My teeth feel smarter because of it even if my toothbrush isn’t one of those sneaky smart ones.

  6. The only smart devices we have are our iphones, but I think I’ll keep an eye on my microwave from now on. 🙂 I’ve never heard of smart toothbrushes, but what a story! I’ll check out the dental floss though. And yes, for soft bristles!
