Security researchers in Canada and Israel have discovered a way to take over the Internet of Things (IoT) from the sky. Okay, that's a little dramatic, but the researchers were able to take control of some Philips Hue lights using a drone. Based on an exploit for the ZigBee Light Link Touchlink system, white hat hackers were able to remotely control the Hue lights via drone and cause them to blink S-O-S in Morse code. The drone carried out the attack from more than a thousand feet away. Using the exploit, the researchers were able to bypass any prohibitions against remote access of the networked light bulbs, and then install malicious firmware.
