We can't live our modern lives without smartphones. However, these devices also impact our privacy and pose several security concerns. From unauthorised eavesdropping to surveillance and tracking, there are significant risks that come with this technology. Despite advancements in technology, no device is entirely immune to these challenges.
Mobile Phone Eavesdropping
One significant vulnerability is the microphones embedded within your phone. While they are essential for the phone to function, they can also be exploited by hackers, app developers or advertising companies. The key risks include;
- The primary microphone is the main microphone on a device, typically used for voice calls, voice recordings, and voice commands. While essential for many functions, it's also a potential entry point for unauthorised listening. A solution people employ is the use of physical microphone blockers to disable the microphone when not in use.
- The secondary microphone is often used for voice assistance or noise cancelling and can be activated even when the primary microphone is disabled. Not every phone has a second microphone, but the ones that do come with additional security risks. It means that even if you've taken steps to disable your primary microphone, you may still be vulnerable to eavesdropping.
- Voice assistants like Siri or Google Assistant can introduce security risks. These assistants can be remotely activated by using keywords and, as a result, allow unauthorised access to your device.
Take Control of Your Microphone
To mitigate these risks, consider implementing the following security measures:
- Disable voice assistants to prevent remote microphone activation and reduce the risk of eavesdropping.
- A microphone blocker can provide an effective layer of protection by simulating a connected microphone to disable the primary microphone.
- Be careful with third-party apps and only download apps from authorised app stores (Google Play, Apple App Store). Don't give them permission to use the microphone. Apps from unknown sources require extra caution as they could contain malicious code.
- Stay informed and keep up-to-date with the latest security news and vulnerabilities. Understanding the trends in security can help you take proactive steps to protect yourself.
Mobile Phone Tracking
Beyond the threat of eavesdropping, your smartphone can also be used as a tracking device, even when turned off. Tracking technologies such as GPS, Wi-Fi, and Bluetooth enable this capability.
- GPS tracking is used for navigation services and lets your phone pinpoint your location. While it's an important feature for modern phones, it can also monitor your movements.
- Wi-Fi tracking as you connect to Wi-Fi networks enables your phone to be tracked even indoors. Your phone's unique identifier can be logged by Wi-Fi routers, revealing your whereabouts.
- Bluetooth tracking makes it possible to determine your approximate location by analysing Bluetooth signals. Bluetooth signals can be used to estimate your location even when GPS is turned off.
Stop Location Tracking
To prevent your phone from being tracked, take these steps:
- Disable location services for apps that don't require them, including built-in apps on your phone.
- Limit app permissions and be selective about which apps can access your location data.
- Use a Faraday bag that blocks wireless signals, preventing your phone from being tracked or hacked.
- Regularly update your software and your phone's operating system and apps up-to-date to address security vulnerabilities.
The Trade-off Between Convenience and Security
It's important to recognise that complete security often requires sacrificing some convenience. You can prevent the privacy and security implications of phone use by being aware of the risks and following these simple tips.
