    Proprietary software is often locked down to be idiot proof and tamper proof to the average consumer. Actually disabling the wifi (not just turning off SSID broadcasting) or other exploitable points might require a deeper level of access than just the settings page.

    And it’s not websites people are concerned about. There’s a pretty common hacking concept where you attack the weakest connected device. If your car connects to your garage door opener, your coffee maker, your washing machine, all your smart devices - they only need to get access to one to get access to all of them since those devices are ‘trusted’. Your car doesn’t know why your coffee maker says ‘unlock’ but it’s gonna listen, it trusts your coffee machine.

      No. That’s not how it works. That’s not how any of this work.

      A car does not automatically accept commands to devices it connects to because of some inherent trust. The car would be programmed to only accept commands from devices it expects to send it such commands.

      Anyone who allows the toaster to not only command the car but alap unlock the car should be fired and blackballed from the industry. That’s not a whoopsie, learning experience. That’s an unforgivable level of incompetence.

        I simplified the concept which might seem misleading to you but the outcome is exactly the same.

        You can get access to the home network through weakly secured devices. If you can get past a weak device, trusted by the network, you can send commands through the network and to other devices as if you were a typical user. If your car can be unlocked from your computer (or phone) over the network, a hacker would only need to get past your coffee maker on that same network to be able to tell your car to unlock.

        In other words, the Internet of Things can often be a liability if you don’t know how to secure points of access to your network. If you installed a smart thermostat and it’s still broadcasting the default SSID, that’s a glowing weakspot for a hacker. Who would need WPA2 security for that, right?

          From the toaster you’d still need to find a way to access a trusted device. This is going to require an exploit. But first the toaster needs meet some specific requirements, like does it have a web server or shell. If it’s a simple device that merely broadcasts its state it likely does it meet these requirements.

          If your WiFi thermostat is broadcasting its default SSID, that means it is not connected to your WiFi. At most you can take control of the device but it won’t get you onto the trusted network any faster than hacking their WiFi directly. Best to go for a device already on the network.
