This guy’s light bulb performed a DoS attack on his entire smart house

About two years ago, Rojas’s house froze up, and stopped responding to his commands. “Nothing worked. I couldn’t turn the lights on or off. It got stuck,” he says. It was like when the beach ball of death begins spinning on your computer—except it was his entire home.

It wasn’t quite as bad as the “nightmare on connected home street” dreamed up by Wired last year, in which a fictional smart home’s obsolete technology gets loaded up with viruses and malware and starts misbehaving and uploading naked photos of its owner. Rojas—a professor who specializes in artificial intelligence—knows his way around a network well enough to cure his own home. And, when he investigated, it turned out that the culprit was a single, connected light bulb.
