Matthew Garrett is a security developer at CoreOS who also buys Internet of Things devices on Amazon and writes security reviews about them. Among his purchased and reviewed gadgets are seven smart bulbs and the AuYou Wi-Fi Switch, which lets users remotely turn their home sockets on and off. His writeup, titled “Nice hardware, infuriating setup issues, terrible insecure software,” dives deep into the security of this Chinese-manufactured switch that he says exposes the MAC address of users’ sockets.
“In summary: by default [AuYou Wi-Fi Switch] is stupendously insecure, there’s no reasonable way to make it secure, and if you do make it secure then it’s much less useful than it’s supposed to be,” he wrote. “Don’t buy it.”
