Two security researchers from the Weizmann Institute have shown how hackers can target connected lightbulbs to steal sensitive data from Air-Gapped networks. The hacking technique relies on modulate light pulses in two commercial bulbs, a Philips Hue and a LimitlessLED, to transfer data up to 100 meters away. Hackers can control the light intensity to create strobes in the most sensitive frequencies, creating a shocking effect. The research confirms the necessity of a security by design approach for all the devices belonging to the Internet of Things.”]
