Do you know how many Bluetooth-enabled devices are currently present in the world? With the beginning of the IoT (Internet of Things) and Smart Bluetooth (Low energy) we find in our hands almost a zillion of them. Are they secure? What if I tell you I can unlock your Smartphone? What if I tell you I'm able to open the new shiny SmartLock you are using to secure your house's door?
In this talk we will explain briefly how the Bluetooth (BDR/EDR/LE) protocols work, focusing on security aspects. We will show then some known vulnerabilities and finally we will consider deeply undisclosed ones, even with live demonstrations.
