A study performed at the University of Texas at San Antonio (UTSA) revealed that some smart light bulbs purchased for home use could become a target for hackers foraging for personal information.
Some smart bulbs can connect to a home network directly, without needing a smart home hub (a centralized hardware or software device that enables IoT products to communicate with each other). If these bulbs are IR-enabled, a hacker could send commands via the IR light that is emitted by the bulb to either steal data or spoof other IoT devices connected on the home network. The owner might not know about the hack because the hacking commands would be communicated within the owner’s home Wi-Fi network, without using the internet.
