Fitness Tracker: Hack in Progress

This talk is about hacking a well-known fitness wristband, the Fitbit Flex. Wearables are extremely trendy nowadays, but actually, we know little about their security: what information do they send on us? how reliable are they ? can they be hacked? etc. The fact they rely on proprietary protocols does not help. So, precisely, we focus on understanding the communication with the tracker. Eventually, that's how we learn how to turn the Flex into a wearable random number generator.
