ZigBee is a vital component of several emerging technologies including smart grid systems, bridging the devices in your home with the electric utility. With the rush to deploy this technology, few organizations have examined the security threats in this suddenly "critical infrastructure" wireless protocol. Over the past 9 months, Josh has been assessing various implementations of ZigBee technology while building a tool suite designed to exploit these networks. In this talk, the author will present several findings regarding the vulnerabilities in ZigBee networks, demonstrating the KillerBee attack framework designed to exploit ZigBee networks.
