Researchers from the Weizmann Institute of Science and Dalhousie University executed the chain-reaction attack by exploiting a vulnerability in the ZigBee wireless communications protocol, a widely used home automation protocol found at the center of millions of smart home devices.
Philips Hue lighting is just one example. Other notable ZigBee devices include the Nest thermostat and Logitech Harmony Ultimate home control hub. The infected payload was delivered by exploiting a weakness in Philips’ encryption to force an over-the-air firmware update using an autonomous attack kit built from equipment costing a few hundred dollars. Basically, anyone with the knowledge could execute a similar attack.
Of course, Philips was notified about the vulnerability and a patch was immediately issued.
