Smart Bulbs at Risk?

In a recent article on the website, govtech.com, the idea of cybersecurity for smart light bulbs is discussed. With regard to ZigBee and Z-Wave protocol, researchers have found major security flaws in smart light bulbs. Tests conducted on Phillips Hue light bulbs showed that they were able to be ‘infected’ with a code that can spread from lightbulb to light bulb. This is done by having a drone fly within a close proximity and transmit to the light bulbs and then control them remotely. How will companies in the IoT business combat these potential security breaches? Will this slow the growth of the IoT industry? What negative impacts will be felt?
