Developer Joshua Wright intends to release KillerBee, an open source collectionPDF of Linux tools intended for testing the security of ZigBee networks. According to Wright, many ZigBee implementations are a mess – he hopes that his tool, which is coded in Python, will ultimately lead to more secure products. Wright lists ZigBee applications which include controlling water flows in dams and natural gas control valves. The technology is also widely used in building automation; many thousands of ZigBee devices have been used in the brand-new MGM CityCenter in Las Vegas, for example. Some intelligent electricity meters in use in the US also communicate using ZigBee in a mesh network.
