Internet Of Not-So-Smart Things: Samsung's Latest Smart Fridge Can Expose Your Gmail Password
from the I'll-take-my-devices-stupid,-thanks dept
The latest example comes again via Samsung, whose "smart" refrigerators aren't so smart. While Samsung's shiny new refrigerators connect to the Internet, can display your Google Calendar and implement SSL, hackers during a challenge at the recent DEFCON found the refrigerators fail to validate those SSL certificates. That opens the door to all kinds of man-in-the-middle attacks, potentially allowing your neighbor to steal your Gmail login information while sitting on his couch next door:
"The internet-connected fridge is designed to display Gmail Calendar information on its display," explained Ken Munro, a security researcher at Pen Test Partners. "It appears to work the same way that any device running a Gmail calendar does. A logged-in user/owner of the calendar makes updates and those changes are then seen on any device that a user can view the calendar on."On the plus side, this vulnerability was found after Samsung invited hackers to try and find vulnerabilities in the system, showing some proactive thinking. On the flip side, this is the same company whose "smart" TVs were found to be happily sending living room conversation snippets unencrypted over the Internet -- so it's not always clear Samsung listens to feedback, or how many bugs and vulnerabilities go unnoticed. Regardless, the researchers' blog post has a little more detail, noting they may have also found some vulnerabilities in the app's encrypted communication stream with the refrigerator.
"While SSL is in place, the fridge fails to validate the certificate. Hence, hackers who manage to access the network that the fridge is on (perhaps through a de-authentication and fake Wi-Fi access point attack) can Man-In-The-Middle the fridge calendar client and steal Google login credentials from their neighbours, for example."
These endless IOT security issues may have the opposite effect of that intended: actively marketing the need for many devices to be dumber. And those dumb devices are getting harder to find. Many of the latest and greatest 4K television sets, for example, simply can't be purchased without intelligent internals that integrate functionality the user may not want. So while Wired magazine's endless 1990's obsession with intelligent refrigerators may have finally come to fruition, they may be unwitting pitchmen for how sometimes it's better for things to simply remain utterly analog -- and beautifully, simply stupid.
