Portable speakers, cars, mobile phones, watches, and other wireless-enabled devices.

Bluetooth is a wireless communication protocol invented by Dr. Jaap Haartsen in the late 90s to simplify the transfer of documents, photos, and files for less bulky peripheral devices over short-range distances. Still, it's not without its Bluetooth vulnerabilities.

Unfortunately, the evolution of wireless communication between frequently used devices like Mobile phones, PDAs, Computers, and others has been made possible by Bluetooth technology. However, this has also introduced Bluetooth vulnerability and security challenges for developers and users of Bluetooth communication and their data.

What Is Bluetooth Hacking?

What Is Bluetooth Hacking?

Bluetooth hacking occurs when hackers, sometimes referred to as Bluetooth hackers, gain access to an unsuspecting user's data with the help of malicious malware and other tools. This raises the question of whether Bluetooth can be hacked.

Indeed, hackers can breach your Bluetooth-enabled devices through the vulnerability found in the Bluetooth 5 specification discovered by security researchers from Finland.

In addition, Bluetooth hacking can also be possible via eavesdropping, which is common among older devices using outdated Bluetooth technology, prompting users to monitor Bluetooth activity with an unpatched security vulnerability.

How To Prevent Bluetooth Hacking

Also, some of the Bluetooth security concerns are vulnerabilities like Bleedingbit and BlueBorne, which hackers mainly remotely exploit to gain access to the victim's device.

car hacking bluetooth security issues

The phenomenon of car hacking through Bluetooth, often referred to as a Bluetooth scam, has emerged as a significant security concern within the automobile industry. Two security researchers once demonstrated how possible it was to hack and hijack a moving car on a highway.

Besides that, cybersecurity experts and automakers agree that internet and Bluetooth-connected cars are as vulnerable to malicious hack attacks as every other internet-connected invention.

They revealed the vulnerability in automobile networks that can be breached and manipulated by maneuvering through the security protocols set in cars to protect against hacks.

Research reveals that vehicles with wireless connections like Bluetooth, mobile phone services, radios, and Wi-Fi are vulnerable to hackers' malicious attacks through remote commands.

How To Prevent Bluetooth Hacking

How To Prevent Bluetooth Hacking

Understanding the various vulnerabilities and methods that hackers employ to attack your devices maliciously is crucial. So, what is the best method to prevent Bluetooth from being exploited? This question is pivotal in enhancing Bluetooth security.

Here are some Bluetooth hacking methods and how to prevent them:

  1. Hackers can crash your digital device, blocking you from receiving text messages or calls. It might be best to turn off your Bluetooth connection when not in use.
  2. Hackers can tap into your phone conversations via Bluetooth headsets and other hands-free devices using a mobile bug with Joshua Wright, having shown severe vulnerabilities discovered in significant headset brands. Turning off your Bluetooth visibility and changing your default code to more complex code can help reduce this threat.
  3. If you make phone calls with your Bluetooth device from your car, have them switched off before getting out.
  4. When you are involved in a first-time pairing of devices, ensure it is done at home or in the office and not in a public place since hackers mainly target users of public Wi-Fi.
  5. Always download and update your devices' software to the latest versions because most updates from your device makers come with security patches that help fight against hacks and security threats.
  6. Avoid pairing your device with an unrecognized source. Never accept pairing requests when unsure of the other party's identity.
  7. To protect yourself against the BlueBorne attack, ensure you never use public Wi-Fi and VPN services as a protective measure.

How To Prevent Bluetooth Hacking: A Guide

How To Prevent Bluetooth Hacking A Guide

Turn off Bluetooth when not in use:This makes your device invisible to other Bluetooth devices, significantly reducing the attack surface.It saves battery life and eliminates most hacking risks.
Only pair with trusted devices:Be cautious about pairing with unknown devices, especially in public places. Only connect to devices you recognize and trust.Minimizes the risk of connecting to malicious devices.
Set your device to “invisible” or “non-discoverable”:This hides your device from being seen by other Bluetooth devices unless you initiate pairing.It makes it harder for hackers to target your device precisely.
Use strong passwords or PINs for pairing:Weak passwords are easy to crack, increasing the risk of unauthorized access. Choose complex passwords and change them regularly.Adds an extra layer of security to prevent unauthorized pairing.

Is Bluetooth Secure?

bluetooth communication

Like internet-connected devices, a Bluetooth connection is susceptible to cyber threats, with Bluetooth hijack apps being a prime example.

Cybercriminals have been known to exploit Bluetooth's ‘discovery mode' on devices, a technique known as ‘how to hijack Bluetooth' to extract information from unsuspecting users for nefarious purposes.

how to hijack Bluetooth

The susceptibility of Bluetooth communication extends to bluesnarfing, a method where hackers use tools like Obexftp and hcitool to gain unauthorized access and retrieve information such as texts, call logs, and emails.

Understanding what bluesnarfing is is essential for safeguarding against such intrusions.

What Is The Best Method To Prevent Bluetooth From Being Exploited?

To shield your Bluetooth-enabled devices from hacking attempts, it's advisable to turn off Bluetooth or disable Bluetooth when not in use and to use strong passwords for an added layer of security.

Regular phone users must be wary of Bluetooth phone hacks, such as bluejacking, where hackers use advanced software to mimic trusted devices and deceive Bluetooth-enabled devices into connecting with them.

An effective measure to secure your device against hacking is to turn off Bluetooth, particularly the Discoverable mode, which makes your device invisible to other Bluetooth scanners when not actively in use.

However, this countermeasure isn't foolproof – hackers have figured out ways to exploit this vulnerability. One such example is Joshua Wright's demonstration of hacking a Bluetooth device using a directional high-gain antenna.

Bluetooth impersonation attacks

Bluetooth impersonation attacks are another way hackers can take over your device. The attacker uses software and hardware that can intercept Bluetooth handshakes, which are used to pair two devices.

Once he can intercept this data, he can manipulate passwords and sensitive information. It's not difficult to imagine the dire consequences for a person whose paired device has been compromised.

Another joint attack is the man-in-the-middle Bluetooth attack. With this technique, an attacker has to be close to the connected devices to collect data packets. Similarly, many Bluetooth speakers have vulnerabilities in their firmware.

By exploiting these vulnerabilities, an attacker can gain control of the speaker. In addition, many people do not bother to turn off their Bluetooth speakers when not in use.

In addition to limiting the time your Bluetooth device is enabled, you should ensure it has a robust Bluetooth security code to prevent hackers from gaining access to sensitive data. Furthermore, if you have a Bluetooth speaker, you should update its firmware regularly to patch any vulnerabilities.

Blue snarfing

Bluetooth speakers should also be turned off when not in use, as hackers can exploit these devices. If you want to ensure your Bluetooth speaker stays secure, you should use the latest versions of these apps.

Blue snarfing is another type of Bluetooth hack. It is possible to be bluesnared from 300 feet away. Using this method, it is easy for a skilled hacker to hijack a victim's phone.

This attack relies on a vulnerability in Bluetooth's OBEX protocol, allowing it to exchange information wirelessly. The OBEX protocol is known to have a security flaw, so it's crucial to protect yourself from this blue snarfing attack.


Hackers are not slowing down in their quest to gain wealth and “popularity” through malicious means. It is your responsibility to protect yourself from Bluetooth hackers. Taking your security seriously can never be too much.

Applying the tips mentioned earlier can prevent Bluetooth hacking on your digital devices. Additionally, using reliable security solutions to protect your digital devices would be best.
