We've talked a lot about the security of SmartHome devices, but when it comes down to it, the most important step in securing your smart home equipment is securing your Wi-Fi network, plain and simple.
Recently, hacker and security attorney Jerry Gamblin was able to easily restart his Google Home Hub from his laptop with a simple
curl command. I was able to replicate this myself with Terminal on macOS, and in fact I was able to restart my Home Hub on the ground floor from my upstairs home office.
Also Gamblin was able to disable notifications Even delete the Home Hub's Wi-Fi settings that "disable the device until you reconfigure it manually with the Google Home application." No wonder, Gamblin is "extremely disappointed" and "really shocked" because the Home Hub provides inadequate security. 19659002] The catch, however, is that you need to be connected to the same Wi-Fi network as the Home Hub for this to work. While you do not have complete control over the security of your SmartHome devices, you have at least complete control over the security of your Wi-Fi network. Make sure that you use at least one WPA2 encryption in your wireless router with a strong password so that anyone who does not have access to your wireless network can not do so.
Of course, as noted by Gamblin shared Wi-Fi networks (as in schools, dorms, businesses, etc.) are more of a problem here, and someone on these networks could easily get in with a Google Home Hub to beat the hall.
