Do you often leave your smartphone Bluetooth in discovery mode? Well, then, you might be susceptible to hackers who may be just 10-m away from you. Hackers use a method known as Bluebugging to record phone calls, modify text messages, and gain access to important data. It also allows hackers to copy contacts onto their own devices and then get in touch with them to scam them. While this started out as a major threat to laptops, hackers have developed techniques to get into one’s smartphone as well.

How does it work?

If your device’s Bluetooth is set to discoverable mode, it will allow hackers to connect with it and exploit it. It is important to note that the discoverable mode is generally the default mode on many smartphones, which is why you must manually change it to ensure your safety. Once the hacker has managed to pair with your Bluetooth, they can then use brute force in order to bypass authentication requirements and gain access to the data on your smartphone. All they need to do is install the malware in order to gain access to the same. 

Which device can be hacked by Bluebugging?

Any device that supports Bluetooth connectivity is susceptible to this threat. Hackers can also use TWS earphones in order to record your conversations and gain important information that way.

Can you prevent Bluebugging?

There are a few things you can do to prevent hackers from breaking into your smartphone via Bluetooth. These include:

  • Turning off your Bluetooth when it's not in use
  • Avoiding connecting your smartphone to public Wi-Fi
  • Using VPN for additional security 
  • Ensuring your system software is always updated 

These steps can help you prevent hackers from breaking into your smartphone and installing the malware needed to hack it.
