Drilling open a smart door lock in 4 seconds
The BBC asked us to have a look at some smart locks for a TV show recently. We didn’t have much prep time, but were genuinely shocked by just how easy this one was to compromise. Usually, we spend time looking at Bluetooth/RF, the mobile app, the API and then move on to hardware. This […]
