Security researchers have discovered a glaring security hole that exposes the home network password of users of a Wi-Fi-enabled video doorbell. The issue – now resolved – underlines how default configurations of IoT components can introduce easy to exploit security holes.
The Ring allows punters to answer people knocking on your door from your mobile phone, even when you’re not at home. The kit acts as a CCTV camera, automatically activating if people approach your door, letting homeowners talk to visitors, delivery couriers and so on.
There’s an optional feature that allows the kit to hook up to some smart door locks, so users can let guests into their home even when they aren’t in. …The device is secured outside a house using two commonly available Torx T4 screws, leaving it vulnerable to theft. Ring offer a free replacement if the kit is stolen, so homeowners are covered in that scenario (at least).
However that’s not the end of the problems with the device. An easy attack makes it all too simple to steal a homeowner’s Wi-Fi key. To do this, hackers would need to take the kit off the door mounting, flip it over and press the orange “set up” button.
“Pressing the setup button [puts] the doorbell’s wireless module (a Gainspan wireless unit) into a setup mode, in which it acts as a Wi-Fi access point, Pen Test Partners consultant David Lodge explains in a blog post. “By connecting to a web server running on the Gainspan unit, the wireless configuration is returned including the configured SSID and PSK in cleartext,”
A colleague of calls the Internet of Things, the Internet of Targets — how true.
