A pair of information security specialists at Universita di Catania, working with a colleague from the University of London, have found four security vulnerabilities in one of TP-Link’s most popular smart-bulbs. Davide Bonaventura, Giampaolo Bella and Sergio Esposito have written a paper describing their testing of the smart-bulb and what they found. They have posted it on the arXiv preprint server.
