Smart home devices are becoming more popular and convenient, but they also pose some serious security risks. Hackers can target these devices to access your personal information as well as spy on your activities or cause damage to your home or business.
Often the dangers of smart home devices fall under the radar. Seventy-five percent of people feel some level of distrust about the use of their data. Yet most people are willing to use smart home technology.
As we enjoy the convenience of smart living, it’s crucial to be vigilant about cyber threats.
If a hacker has compromised your smart system without you even knowing it, how can you tell? Here are some signs to look out for:
1. Unexpected Behavior
Unexpected behavior is the first sign someone has compromised your smart home device. If your device starts acting erratically, it’s time to investigate. Erratic behavior can include:
- Lights flickering
- Thermostat settings changing
- Smart locks behaving unpredictably
Hackers often manipulate smart devices to create disturbances. Noticing these irregularities early can prevent further damage.
2. Unusual Network Traffic
Monitoring your home network is a fundamental aspect of cybersecurity. Have you observed a sudden surge in data usage? Noticed unusual patterns in network traffic? If so, this could indicate unauthorized access.
Hackers may exploit your smart devices to launch attacks or steal sensitive information. To help stay vigilant against abnormal network behavior, regularly check your router’s activity logs.
3. Strange Sounds or Voices
Smart speakers and voice-activated assistants have become commonplace in many households. If you start hearing unfamiliar voices or strange sounds from these devices, it’s a red flag.
Hackers may use compromised devices to eavesdrop or communicate with people nearby, posing serious privacy concerns. Ensure that your smart devices are only responding to authorized voices.
4. Device Settings Modification
Smart devices offer customizable settings to cater to individual preferences. Have you noticed unauthorized changes to these settings such as alterations in camera angles, sensor sensitivity, or device preferences? If so, there’s a chance that a hacker has compromised your device.
Regularly review and update your device settings. This helps you maintain control over your smart home ecosystem.
5. Unexplained Data Transfers
Smart devices often collect and send data to the cloud for analysis or storage. Keep an eye on your device’s data usage and be wary of unexplained data transfers. Hackers may exploit vulnerabilities to extract sensitive information from your devices.
Regularly review the data usage patterns of your smart devices. This helps you to identify any suspicious activity.
6. Device Inaccessibility
Suddenly finding yourself locked out of your smart home devices could be a sign of hacking. Hackers may change passwords or enable two-factor authentication without your consent. They can take control of your accounts rendering you unable to access or manage your devices.
Always act promptly to regain control. Secure your accounts if you suspect unauthorized access.
7. New or Unknown Devices on the Network
Review the list of devices connected to your home network. Do you spot unfamiliar or unauthorized devices? If so, it’s a clear sign that someone may have breached your network.
Hackers often attempt to connect to your network, looking for vulnerabilities in smart devices to launch attacks. Secure your network with strong passwords. Also, consider implementing network segmentation for added protection.
8. Frequent Software Glitches
Smart devices should receive regular software updates. These updates patch vulnerabilities and enhance security. Have you noticed frequent software glitches? Or has your device failed to update? It could be a sign of interference by a malicious actor.
Confirm that your smart devices are running the latest firmware. This ensures it has the latest security patches and bug fixes installed. Once a device is no longer supported by the manufacturer, consider replacing the device to prevent outdated software from being compromised.
9. Emails or Messages Confirming Changes You Didn’t Make
Some smart devices send notifications or emails to confirm changes in settings, passwords, or device access. Did you receive such confirmations for actions you didn’t take? If so, this is a possible sign of unauthorized access.
Take immediate action to secure your account. This includes changing passwords and reviewing access permissions.
