Bluetooth Smart (BLE) is popping up everywhere. Unfortunately, its security has a fundamental flaw that allows attackers to crack the encryption and read your sensitive data. This talk describes Mike's work sniffing BLE with Ubertooth and describes crackle, a tool to automatically break BLE's encryption. Finally it wraps up with a backward-compatible fix that can be implemented today.
