Researchers at the Synopsys Cybersecurity Research Center (CyRC) have discovered an availability vulnerability in the IKEA TRÅDFRI smart lighting system.
An attacker sending a single malformed IEEE 802.15.4 (Zigbee) frame makes the TRÅDFRI bulb blink, and if they replay (i.e. resend) the same frame multiple times, the bulb performs a factory reset. This causes the bulb to lose configuration information about the Zigbee network and current brightness level. After this attack, all lights are on with full brightness, and a user cannot control the bulbs with either the IKEA Home Smart app or the TRÅDFRI remote control.
To illustrate how this would affect a user, Jonathan Knudsen, head of global research, Synopsys Cybersecurity Research Centre, shows a demo on how an attacker can exploit the vulnerability in smart lighting in this short one and half minute video (https://youtu.be/5BwiyaWg_8o)
