The Hidden Risks of Unsupported IoT Tech

The Internet of Things (IoT) has transformed our lives both for the better and for the worse. For example, on hot days, you can remotely turn on your air conditioner, ensuring your rooms are cool when you arrive home. The more smart devices you have in your home, the better the convenience and comfort.

But did you know that many of them are ticking time bombs, especially if you’ve been using outdated models? The increasing number of IoT security risks demands that people both determine potential threats and take steps to protect their devices.

Why Old IoT Devices Pose a Security Risk

Unlike smartphones or computers, many IoT devices have short support lifespans. Once a company discontinues updates, security flaws remain open for attackers to exploit. They can expose you to data breaches, unauthorized access, and full-scale network intrusions. Hackers actively scan networks for these vulnerabilities, often using them as entry points to access other connected devices.

Here are some of the biggest risks posed by outdated IoT devices.

Smart Home Hubs Can Be Hijacked

Smart home hubs control devices like lights, thermostats, locks, and alarms. A malicious actor could access your entire network using only one hacked smart lightbulb. From this point, they can:

• Disable security alarms, making break-ins easier.
• Turn off cameras, preventing surveillance.
• Manipulate lighting and temperature settings.

Vulnerable Smart Locks Could Let Intruders In

With smart locks, forgetting your keys is no longer a problem. However, older models with weak encryption or other security flaws can be hacked remotely. Attackers can:

• Clone digital keys to gain unauthorized access.
• Exploit software bugs to unlock doors remotely.
• Use brute-force attacks to bypass outdated security measures.

Hacked Security Cameras Can Spy on You

Security cameras are supposed to protect your home, but outdated models can serve the opposite purpose. In 2018, a baby monitor was hacked, with criminals threatening parents to kidnap their child. If your security camera gets compromised, attackers can:

• Watch live footage without your consent.
• Disable your camera feed before a break-in.
• Steal recorded video for blackmail or surveillance.

Smartwatches and Fitness Trackers Leak Personal Data

The smartwatch or fitness tracker you love to use when you work out is storing sensitive information. This includes health data, GPS locations, and login credentials. If this device stops receiving security updates, hackers can:

• Track your daily movements using GPS data.
• Access health records and personal details stored in companion apps.
• Exploit Bluetooth vulnerabilities to hijack devices.

Smart TVs Can Be Used for Surveillance or Data Theft

Smart TVs enable you to link your devices with streaming platforms, social networks, and email services through their system. When an older TV model gets compromised, hackers gain access to:

• Stream accounts while also viewing your payment information.
• Operate the TV’s microphone or camera without your knowledge.
• Use the TV system to transmit malware, which can affect multiple devices.

In 2019, hackers took control of Chromecast devices and smart TVs, forcing them to display unauthorized videos promoting a YouTube channel. Researchers keep discovering more vulnerabilities, but they are not always fixed promptly (if they are fixed at all).

How to Protect Yourself from IoT Threats

The cybersecurity of IoT devices is crucial because they typically lack built-in defense mechanisms. Here’s how to stay protected.

Don’t Skip Updates

As long as your manufacturer keeps releasing security patches to fix vulnerabilities, don’t ignore them. Always install updates as soon as they’re available. If your device no longer receives updates, consider replacing it.

Upgrade Unsupported Devices

Many older models were not designed with long-term security in mind, making them easier to hack. Investing in newer models not only increases convenience but also keeps your home safer.

Use a VPN to Secure Your Network

Hackers scan home networks looking for vulnerable devices. If you have one or several smart devices, it’s time to put your trust in a virtual private network (VPN). A free VPN download adds extra protection by encrypting your internet traffic. This action prevents attackers from intercepting data, thus gaining unauthorized access to your IoT devices.

Strengthen Password Security

When was the last time you updated the passwords for your IoT devices? Many of them still use default passwords, which are easily hackable. Change them to unique, complex passwords, and enable two-factor authentication whenever possible.

Disable Unnecessary Features

Many IoT devices have extra features, such as remote access, Bluetooth, or voice control, that you may not need. If you’re not using them, turn them off to reduce potential attack points.

Set Up a Separate IoT Network

Most modern routers allow you to create a separate Wi-Fi network just for IoT devices. This means that even if a smart device is hacked, your personal network will stay secure.

The Future of IoT Security

As IoT devices continue to evolve, so do cybersecurity threats. While manufacturers are improving security standards, many still don’t provide long-term support. Governments and industry leaders are pushing for stricter security regulations, but until that becomes standard, you must take precautions.

Some upcoming trends in IoT security include:

• Longer support cycles: More manufacturers are committing to 5+ years of security updates.
• Built-in security features: Devices are incorporating AI-driven threat detection and better encryption.
• Stronger authentication methods: Moving away from weak passwords to biometric verification and hardware-based security keys.

The future looks promising, but for now, keeping up with current safety practices is your best defense.

Summing Up

With more smart devices making their way into homes, keeping them secure has become a real challenge. While IoT gadgets add convenience, they also create new opportunities for hackers to sneak into your network. The good news? You don’t have to give up on smart tech to stay safe. A layered security approach can go a long way in protecting your home.

Smart devices should make life easier, not put your data at risk. The real question isn’t whether they can be hacked. It’s whether you’re taking the right steps to keep them safe.
