No, not yet, but let’s pair two stories:
The idea of the Internet of Things is to let all the dumb things in your house talk to each other, thereby collectively creating a smart world. (If that sounds dumb, remember that all the cells in your body are individually dumb, thereby collectively creating you.) Lots of devices now have some degree of connectivity, like DVRs, security cameras, thermostats you can control via app, keyless locks, or your garage door opener. Now think for a moment: when was the last time you changed the password on those? If you have one of those fancy, programmable toasters that makes a picture on bread, do you even know how to access security on it? Maybe they do not even build security into a toaster.
I remember mocking a headline about hackers “using your blender against you,” because the worst case scenario of a hacked blender seems like a lousy smoothie. So far, the apparent worst case scenario is contributing to a DDoS attack. If we now have millions of insecure, dumb devices online, and many of them can make some online requests, you can now flood anything with requests from millions of vectors. And those devices will continue to be vulnerable until they are out of service. Do you even know how many connections you have to the Internet of Things? If you know every device, can you access its firmware and update its security settings?
Adding in that second article: and now we have proof of concept for letting non-powered devices contribute to the Internet of Things using signals already in the air. “The goal is having billions of disposable devices start communicating,” he says, adding to the millions of insecure devices already doing so. The example in the article is contact lenses, hence my headline.
If we are not building security into the Internet of Things, we are building a world where you could attack a computer literally just by looking at it.
Unrelatedly, did you know that you can damage computers by shouting at them? Sound waves are physical vibrations, and computers can be very sensitive.
