Turn me off, Turn me on

The Zigbee wireless communication protocol is widely used in large industrial automation systems. A successful hack of such a Zigbee network gives an attacker many interesting possibilities - from conducting a devastating DOS attack on equipment to intercepting control of the network coordinator, through which access can be gained to multiple sensors and detectors. The report presents the results of a security analysis of Zigbee networks for one of our clients. In particular, it is shown that using an inexpensive USB dongle, it is possible to sniff network traffic and decrypt it, as well as create Zigbee packets to intercept communication between the network coordinator and its sensors, fully emulating the functions of the coordinator.
