Cyber Warfare(cont.): The Silent War of IoT (Internet of Things)

Imagine stepping into a battlefield. There’s no visible enemy, no sound of conflict, just the quiet hum of your kitchen appliances. You’re reaching for a drink from the fridge when suddenly a screen lights up. That’s your gateway to the battlefield, and the battleground is your own kitchen.

You might wonder, How can a refrigerator be a security threat? Surely it’s just there to keep your food fresh. But in today’s connected world, it could be so much more—a silent participant in a hidden cyber war.

Cybersecurity expert Tom Kellermann once explained, "These smart devices come with everything turned on, everything enabled, and very little security." And that lack of security opens doors to unimaginable vulnerabilities. "You can be extorted, you can be stalked, you can be robbed, and your home network can be commandeered to attack your work network."

It may sound like the start of a thriller movie, but smart refrigerators have already been exploited in cyber-attacks. In 2014, a botnet harnessed over 100,000 smart devices, including refrigerators, to send out more than 750,000 malicious emails. This staggering operation showed just how easily IoT devices could be co-opted into cyber attacks without their owners even knowing.

Think of it: a seemingly harmless fridge in your home unwittingly becomes part of a malicious network. With an internet connection, your fridge is no longer just a cooling unit; it’s a potential entry point for hackers. And anything with a camera or microphone—whether it’s your fridge, smart TV, or voice assistant—could serve as a listening device, putting hackers virtually in your home. That thought alone is chilling.

The surge of IoT threats has sparked significant changes in the industry, aiming to protect consumers. In 2021, the National Institute of Standards and Technology (NIST) released the Special Publication 800-213, which outlines a framework to enhance the security of IoT devices. NIST SP 800-213 establishes guidelines that manufacturers should follow to make their devices safer, from requiring strong authentication to enabling automatic updates to fix known vulnerabilities. These standards are essential steps forward, but the battle is far from over.

So, what can we do in this complex landscape of internet-connected devices? For one, it’s crucial to avoid relying on default settings. Most of these devices come with factory-set passwords, which are often widely known and easily guessed. Changing those passwords to something unique and strong might seem minor, but it adds a critical layer of security. And, if two-factor authentication is an option, take advantage of it—it’s like adding a second lock to your door.

Keeping software up-to-date is another step. Yes, updates can be annoying, especially when they seem to pop up constantly, but they’re there for a reason. These updates fix known issues and strengthen defenses against potential threats. It’s also worth considering how your devices are connected; separating IoT devices onto a guest network keeps them apart from more sensitive devices, like your computer or phone, adding another level of isolation.

All of this may seem overwhelming, but it’s about staying mindful. In the Marines, we were taught to keep our hands out of our pockets. At the time, it seemed like an odd rule—especially in freezing weather—but the logic was simple: hands at the ready make you a harder target. It wasn’t just about posture; it was a mentality of always being prepared, always being aware.

We should apply this mentality to our online security and our IoT devices. We can’t afford to be complacent. By making small but essential changes in how we manage these devices, we create a harder target for anyone attempting to infiltrate our digital lives. This isn’t about paranoia; it’s about preparation and resilience.

In the end, our kitchens, living rooms, and entire homes are connected to an invisible world where threats can lurk. By taking steps to secure our IoT devices, we aren’t just protecting our privacy; we’re taking control of our modern battlefield.
