Everyday Devices That Can Be Hacked — And How to Protect Yourself

The Internet of Things (IoT) has transformed everyday life. From smart thermostats to connected doorbells, technology now makes our homes more efficient, comfortable, and secure. However, these same conveniences also introduce serious privacy and security risks—especially for seniors, who may be less familiar with the hidden dangers of internet-connected devices.

If you or a loved one uses smart technology, it’s essential to understand how hackers exploit these tools—and how to safeguard them.

1. Smart TVs

Smart TVs can be hacked more easily than most people realize. Attackers may take control of your device to:

• Change channels, blast the volume, or make unauthorized purchases
• Steal saved credit card data through compromised apps
• Use your TV as a gateway to other smart devices on your home network

Even legitimate TV manufacturers collect and sell data about your viewing habits. To stay safe:

• Change default passwords immediately
• Regularly update your TV’s firmware
• Limit app permissions and disable features you don’t use

2. Smart Thermostats

Smart thermostats save energy—but if hacked, they can cause real harm. Criminals have used ransomware attacks to lock users out of temperature controls until payment is made. For older adults, sudden temperature extremes can pose serious health risks.

Protect yourself by:

• Installing firmware updates as soon as they become available
• Creating a strong, unique password
• Avoiding public Wi-Fi when managing your thermostat remotely

3. Baby Monitors and In-Home Cameras

Many families now use Wi-Fi-enabled cameras or baby monitors to check on loved ones. Unfortunately, hackers can scan for IP addresses and gain access to live feeds—turning private spaces into surveillance opportunities.

To secure your cameras:

• Choose devices designed to be “invisible” to scans
• Change default passwords
• Enable two-factor authentication if available
• Keep your home network password-protected and encrypted

4. Smart Refrigerators

Even kitchen appliances can pose cyber risks. Some smart refrigerators—notably early models from major brands—were found to expose Google account credentials, allowing hackers to access email, calendars, and other linked devices.

Before connecting your fridge to Wi-Fi:

• Review privacy settings carefully
• Disable unnecessary connectivity features
• Keep all apps and software current

5. Voice-Activated Devices (Alexa, Google Home, Echo, etc.)

Voice assistants can make life easier, but they also record and transmit sensitive conversations. Hackers—or even unscrupulous third parties—may intercept data or commands, exposing personal information like doctor appointments, travel plans, or financial details.

Tips for protection:

• Mute microphones when not in use
• Review privacy settings and delete stored recordings regularly
• Avoid linking devices that control your security system or bank accounts

6. Pacemakers and Medical Devices

Although rare, implanted medical devices such as pacemakers and insulin pumps have been proven vulnerable to remote tampering. Manufacturers now employ more robust encryption and monitoring systems, but patients should still:

• Discuss cybersecurity safeguards with their healthcare provider
• Ensure that any connected monitoring apps or transmitters are officially supported and updated

7. Routers, Cell Phones, and Voicemail

Your home Wi-Fi router is the nerve center of your digital life. If compromised, every connected device—from your phone to your smart speaker—can be accessed.

To stay secure:

• Replace outdated routers every 3–5 years
• Update firmware and use a complex, unique password
• Enable network encryption (WPA3 if possible)

Likewise, cell phones and even landline voicemail systems can be hacked. Avoid sharing sensitive data over unsecured networks and consider using signal-blocking cases when in public.

8. Digital Photo Frames

Digital frames that connect to Wi-Fi can display treasured family photos—but if hacked, their sensors can reveal when your home is empty. Thieves could use that information to plan break-ins.

Keep your frame secure by updating its firmware and disabling features that track motion or ambient light when not needed.

9. Smart Garage Door Openers and Cars

Modern garage doors and vehicles rely on wireless connectivity—and hackers can exploit these systems to track your comings and goings or even gain physical access to your home or car.

For protection:

• Always change manufacturer default passwords
• Turn on alerts for unusual activity
• Keep car key fobs in signal-blocking pouches
• Install software updates for any connected vehicle system

10. How to Protect All Your Smart Devices

Convenience should never come at the cost of your security. Follow these best practices to reduce risk:

1. Change all default passwords and use unique, complex ones for every device.
2. Update software and firmware regularly to patch vulnerabilities.
3. Use a secure Wi-Fi network with WPA2 or WPA3 encryption.
4. Avoid public Wi-Fi for managing connected devices.
5. Monitor for suspicious activity—sudden behavior changes may indicate hacking.
6. Enable two-factor authentication wherever available.

Staying Safe in the Age of Smart Technology

The Internet of Things can enhance comfort, independence, and safety for seniors—but it also demands vigilance. By taking simple steps to secure your home network and devices, you can dramatically reduce your exposure to cyber threats.
