But most of them are physical-access only settings. Some systems provide a secure enclave where passwords can be stored, but someway it is usually possible to get it out when you have PHYSICAL ACCESS to a device.Ģ) No security settings ok, this could be improved. Sure, some devices provide an “encrypted partition”, but usually such partition (since the device must start without a password) is encoded with some variation over the serial number or other unique property of the device… and it’s usually not so hard to decipher. X509 cert authentication, but some WPS as well I believe to remember) that don’t rely on that, but they’re harder to setup and support. There’re other, less-used and more complex authentication systems (e.g. What is a “firmware”? You mean the device flash memory? The user must set its credentials, right? So, how is it possible that they’re “in the firmware”, if firmware is the software that gets uploaded by the factory?ġ) Wi-fi credentials stored on a device must be readable by the device somehow when it boots and it wants to connect. “Wi-Fi credentials stored in plaintext into the firmware” Beyond the not-so-reasonable scenario (wouldn’t you be able to tell that your bulb has been tampered with?), the analysis lacks precision.

Maybe you have some valid points, but you fails to illustrate them properly.
