Automate your wake up Schedule, or set up your movie-watching Scene (then set up voice control so you don’t even have to leave the sofa), or play with Effects next time you’re entertaining. LIFX App 4 can not only help give you the best start, but will turn your experience “up to 11”. We make it easy to get started with WiFi-enabled, bright, colorful smart lights that need no hub. This means we care about the way you control your smart lights, as much as we do about the lights themselves. If it’s a single certificate that allows, with such key, ALL devices to authenticate on LIFX server, well, that’s a vulnerability! Otherwise, it’s probably a good practice.Like you, LIFX wants smarter light. Root certificate and private key of what? First, the fact that the certificate is in the firmware is not a problem just the private key could be a problem.īut is that certificate shared and reused between all devices? Or is it flashed per-device and/or autogenerated and trusted on first use? You say nothing about that. The scenario here is a bit different.ģ) Root certificate and RSA private key extracted 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.
