Philips Hue light bulbs could be vulnerable to a cyber attack, according to researchers who have developed a proof-of-concept worm capable of spreading from bulb to bulb with the power to turn the lights on and off. The researchers efforts at gaining access to the connected light bulbs was detailed in their paper titled IoT Goes Nuclear a ZigBee Chain Reaction. The worm they created was able to gain access to the Philips Hue devices by exploiting hard-coded symmetric encryption keys that are used to control devices over Zigbee wireless networks. The worm is able to spread from a single… [Continue Reading]
