Submission + - Sniff and decrypt BLE with Ubertooth (lacklustre.net)

mpeg4codec writes: Hot on the heels of Omri Iluz's BLE-sniffer-on-the-cheap, I decided to write up the BLE (Bluetooth Smart) sniffer I built on Ubertooth. My sniffer is highly robust, can capture data from connections, and is 100% open source.

I also discovered a major flaw in BLE's crypto that allows an attacker to crack its encryption key and decrypt data, 100% passively. I wrote a tool called crackle that will automatically decrypt encrypted BLE data captured by Ubertooth.
