Cybersecurity Strategy To Fight Against Bluetooth Vulnerabilities

Bluetooth is best known as the wireless technology that enables hands-free earpieces and connects your phone to audio, navigation, and electronics through the Internet of Things.

Sadly, a remote attacker could exploit Bluetooth vulnerability to obtain sensitive information. To keep enjoying the benefits of Bluetooth, one should secure his mobile device with Webroot geek squad.


As convenient as Bluetooth can be for productivity and comfort, it can also present major security risks to your device. While most of the problems identified five to ten years ago have been resolved by now, some still remain.

There is also a good reason to be cautious about undiscovered problems. To minimize the risk of cyber attacks on your mobile you can download Webroot’s security software by typing Webroot geek squad download in your browser’s search bar.

A few examples of the mobile security threats in which Bluetooth makes us vulnerable

  1. General software exposures

The software in Bluetooth devices, especially those using the newer Bluetooth 5 specification, is not perfect for your device. It is impossible to find software that has zero security vulnerabilities.

According to a few security researchers, it is easy for attackers to discover new, previously unknown vulnerabilities in Bluetooth devices. Potential impacts could include charges for expensive premium-rate or international calls, theft of sensitive data or accidental malware downloads.

To combat this threat: You should switch off your Bluetooth when not in use.

  1. Spying and Eavesdropping

Bluetooth is all about wireless communication and Bluetooth encryption is supposed to stop criminals listening in to your phone calls or spying through your data.

In other words, eavesdropping should not be an issue. However, older Bluetooth devices that use outdated versions of the Bluetooth will likely face the threat of unpatched security holes that may harm their device.

To combat this threat: Devices that use Bluetooth 1.x, 2.0, or 4.0-LE should be banned and ensure that devices use the latest versions and protocols. 

  1. Service Denial

 Malicious attackers may crash your devices, block them from receiving phone calls and drain your battery, which can be very heartbreaking.

To combat this threat: Again, switch off your Bluetooth when not in use.

  1. Bluetooth range is beyond your thinking

Bluetooth is designed to be a “personal area network”, that is to say, devices that are more than a few feet away cannot be accessed via Bluetooth. However, you’re not safe if you simply ensure there’s a distance between you and a potential hacker. Hackers use directional, high-gain antennas to communicate over much greater distances successfully.

To combat this threat: Once again, switch off your Bluetooth when not in use.

  1. Flaws in Bluetooth headsets

 Researchers have also demonstrated serious flaws in many popular Bluetooth headsets. By abusing these vulnerabilities, attackers can eavesdrop on your conversations with the people around you, not just your phone calls, but built-in hands-free car kits can also be vulnerable.

The device becomes a mobile bugging device, transmitting everything it hears to an attacker.

To combat this threat: Make sure to change the default PIN code to something hard to guess.


It is necessary to develop and communicate the company’s mobile device security policy so that your business’ data is not compromised, and your end users can work safely with mobile. Geek Squad Webroot can also help troubleshoot Bluetooth related issues.

One should keep in mind that mobile devices present a variety of risks that need to be addressed, and Bluetooth security is just one often-overlooked piece of mobile security riddle. Be sure to include mobile device security as part of your cybersecurity strategy.
