What To Do If You Catch Your Fridge Spying on You! Survival Tips for a Smart World (Part II)

The Internet of Things - Everything is Connected


Ahh…. IoT.

If those three little letters don’t strike at least a bit of fear in your heart already, then they probably will after you read this.

If you recall from Part I, the Internet of Things (IoT) affords people with lots of cool and exciting conveniences. But before you run off to buy a computer chip for your goldfish, it would be wise to remember that every device that’s connected to the internet can become a target to hackers. And as you may imagine, that’s not always a good thing. Here are some more reminders that more connectivity is not necessarily better. And after these examples, we’ll give you some tips on how to protect yourself.

Troublesome Traffic Lights

Red means stop, green means go, yellow means … watch out for hackers? In the summer of 2014, researchers at the University of Michigan demonstrated that a typical traffic light is amazingly vulnerable to anyone with a laptop and the right kind of radio. Traffic lights in major cities across the USA use unencrypted (unconcealed) internet connections, and almost all cities fail to change default usernames and passwords.

Such vulnerabilities could potentially be used to make sure that a hacker in a hurry hits all the green lights on his way to work, or for more dubious purposes. (Think “The Italian Job”.)

Refrigerators – Too Smart for Their Own Good

Remember back in the day when the worst issue you could think of in terms of refrigerator “security” was how to protect your Ben and Jerry’s ice cream from being eaten by a sibling? Those days are over (but do go ahead and find a secure spot for that half-full container of Chunky Monkey). According to security firm Proofpoint, in 2014, an internet connected refrigerator was used as part of a botnet attack. A botnet is a group of computers that is being controlled by hackers for malicious purposes. On the surface, the computer seems to be functioning normally. The unwitting user is blissfully unaware of what’s going on internally. In this particular attack, the botnet which the refrigerator was part of sent out thousands of malicious emails.

Then there was the case of the researcher-hacked fridge as part of the exhibits at this year’s DEFCON conference. Held yearly in Las Vegas, DEFCON is where some of the world’s best cyber security researchers and hackers gather to listen to lectures and participate in cyber security related exercises. This exhibit used a Samsung “Smart” fridge that syncs with owners’ Gmail accounts to theoretically help the owner stay on top of daily events from the convenience of their refrigerator door. Hackers demonstrated how the fridge could easily be hacked to expose all of the owners’ Gmail credentials.

Which makes you think that you may be a whole lot safer by opening up your fridge to see if you are low on foodstuffs, and checking your Gmail account the old-fashioned way – from your laptop, PC, mobile phone, or watch.

Hampered Hospital Pumps

You would think that the healthcare industry has enough to worry about when it comes to hacks, but things are getting more complicated here too. Indeed, IofT has added another problem to their collection. This past summer, it was discovered that hospital pumps designed by medical technology manufacturer Hospira contain a critical flaw that allows the pumps to be taken over by hackers. The flaw could enable hackers to change dosage amounts remotely, thereby potentially harming any patient using the pumps. (Told you this would be scary.) Hospira has recalled the pumps and they are no longer being sold, but they are still in use at some hospitals and medical centers.

Billy Rios, the researcher who found the vulnerability, said in an interview These pumps are actually just computers, and so – just as you would take your laptop and join a wireless network, these pumps are on networks as well.” In other words, just like your PC can get a virus if you aren’t careful, so can this type of hospital pump.

The Bright Side (Yes, There is One)

Now, before you lose all faith in the wired world and decide to hunker down in a remote cabin in the mountains where nothing will ever be connected to the internet, take solace in the fact that there are a few things you can do to protect yourself and your family from hacks like these to some degree.

  • Before buying a new appliance, do some research. If you opt for a smart appliance, make sure you are confident about the manufacturer’s security policies. Also make sure that you can change passwords easily.
  • When you get a new smart device, change the factory default passwords and usernames as soon as possible.
  • Keep all of the software relating to these smart devices up-to-date. This way, if a vulnerability is discovered on your smart kettle, smart doorbell or smart baby monitor, you’ll have the patch for it as soon as that patch is released.

The IofT is pretty amazing, but there is a shady side to it all as well. And while there really isn’t much you can do if your traffic lights are hacked, that doesn’t mean you should throw caution to the wind. Protect your home PC with a powerful antivirus software and use common sense when connecting to smart devices. Approaching IoT with both excitement and caution will help you protect yourself, and the people you love.

  • I too worry about security when it comes to the IOT ( Internet of things) and the growing availability of such devices with the potential of not only spying and botnets but also the potential of Governments using such devices as the new back-door into our lives. Many of the devices entering our homes and lives are built abroad ( lowest cost) where the quality and potential security aspects are not considered and in some case dictated by a foreign government. Many of these foreign (sovereign) countries think nothing of spying on their citizens why not export this tracking to foreign countries? IOT could be the springboard to the next level of cyber-crime and cyber-warfare unless considered at the design stages.

    I do have a computer, and I use it quite a bit. And I also use my remote for the TV, but I am just fine turning the lights on by hand, cooking my own food, checking to see if there is enough milk in the fridge. I think people are getting a little to lazy now a days. I am fine with doing things the old fashioned way. I have a large flat screen TV with Internet capabilities, but I never use it. It’s not a smart TV, so I have no use for it. I have a bluray that stays connected so I can stream Netflix, or ultraviolet movies that are in the cloud. But that’s about it.

  • I don’t own a computer but I do enjoy surfing the internet super highway from my refrigerator. I use Norton, AVG, McCafee, SpyBot, Malware Bytes, and Avast to stay protected. My fridge runs slow but at least I know it doesn’t have any Walruses

  • I precisely wished to thank you so much yet again. I’m not certain the things that I would have handled without the techniques shown by you on my area of interest. It actually was the frustrating setting in my opinion, but being able to view the very expert fashion you processed it made me to leap with happiness. Now i am thankful for the guidance and in addition believe you are aware of a great job your are accomplishing instructing men and women by way of your site. More than likely you’ve never met any of us.
