Mike Ryan writes about his latest efforts in BLE hacking.

Hot on the heels of Omri Iluz’s BLE-sniffer-on-the-cheap, I decided to write up the BLE sniffer I built on Ubertooth. My sniffer highly robust, can capture data from connections, and is 100% open source. I also discovered a vulnerability in BLE’s crypto that allows me to crack its encryption key and decrypt traffic — 100% passively.

Here’s a link to the blog post.
