How to Hack Bluetooth Devices? 5 Common Vulnerabilities

How to Hack Bluetooth Devices:- Bluetooth is a wireless technology that allows individuals to be hands-free while connected to mobile devices for audio, navigation, and more. Bluetooth is enabled in many devices such as mobile phones, laptops, iPads and headphones. This may provide an incentive for hackers to compromise this functionality.

Most people always keep his Bluetooth on when it should be on only when really needed. Of course, this is easier said than done and unlikely to be followed. To illustrate the dangers of careless use of Bluetooth, here are five common vulnerabilities that, if exploited, allow hackers to hack Bluetooth devices.

How to Hack Bluetooth Devices?

In contrast to many technological developments, Bluetooth devices have been around for decades and will not be phased out. Instead, developers are constantly changing how they are used. Previously, Bluetooth connectivity was only useful for file transfers. However, there are now many uses for Bluetooth devices and connections.

Smartphones, laptops and other gadgets have become cheaper thanks to Bluetooth connectivity. Additionally, hands-free calling is becoming a popular means of avoiding car accidents. Unfortunately, many Bluetooth vulnerabilities can cause you to lose valuable items.

How to Hack Bluetooth Devices

The main problem is that most people keep her Bluetooth on and always discoverable. Do this even if you won’t be using the Bluetooth connection right away. Hackers and cybercriminals use access to this wireless technology to attack his Bluetooth device. So if you store important data or files on your Bluetooth device, you might want to read up on how your actions could put them at risk.

Common Bluetooth Hacks & Vulnerabilities

  • BlueBorne
  • Bluesnarfing
  • Bluejacking
  • Bluetooth Impersonation Attacks (BIAS)
  • BlueBugging


The name BlueBorne comes from the fact that it “floats in the air and can attack devices via Bluetooth” (Armis). Exploitation of this vulnerability allows hackers to “use Bluetooth connections to infiltrate target devices and gain complete control over them,” Armis.

How to Prevent BlueBorne Attack?

  • Turn off Bluetooth when not in use
  • Update your device’s system software to make sure it’s the latest version
  • Avoid using public Wi-Fi and use a VPN as an extra security measure


A Bluesnarfing attack is a network attack that occurs when a hacker “unwittingly connects to a Bluetooth device to steal or compromise personal information” (Globalsign).

This attack occurs without the victim’s knowledge and works only if he has Bluetooth enabled on his device. Bluesnarfing allows hackers to steal information, potentially leading to more damaging cyberattacks.

How to Prevent Bluetooth Hacks via Bluesnarfing?

  • Turn off Bluetooth when not in use
  • Do not pair with untrusted devices
  • Do not store sensitive information on your Bluetooth device
  • Use strong password/PIN


Bluejacking occurs when “one Bluetooth device hijacks another Bluetooth device and sends spam advertisements, usually with a transmission range of 10 meters or about 30 feet” (AT&T Cybersecurity).

This means hackers can be in the same room as you. This particular attack is used to spam and annoy users’ devices, rather than giving attackers access to the device or its information. Attacks occur without the user’s knowledge.

How to Prevent Bluejacking?

  • Turn off Bluetooth when not in use
  • Ignore incoming spam messages

Bluetooth Impersonation Attacks

Another way attackers hack Bluetooth devices is the Bluetooth spoofing attack. Attackers target the “traditional secure connection authentication procedure during initial secure connection establishment” (h-isac).

The main exploit in the BIAS attack is that “the Bluetooth standard does not require mutual use of traditional authentication methods during establishment of a secure connection” (h-isac). If the exploit is successful, the hacker can act as a man-in-the-middle and intercept sensitive data exchanged between her two connected devices.

How to Prevent BIAS?

The Bluetooth Special Interest Group (SIG) has introduced “mutual authentication requirements along with validation of connection type to prevent connection downgrade attacks” (CPO Magazine).


This exploit was developed after hackers realized how easy a Bluejack or bluesnapping Bluetooth hack could be. BlueBugging “uses Bluetooth to set up a backdoor in the victim’s phone or laptop” (AT&T Cybersecurity). An attacker can not only hack her Bluetooth device, but also view all the data on the device.

How to Prevent BlueBugging?

  • Turn off Bluetooth features when not in use.
  • Do not accept pairing requests from unknown devices.
  • If you’re pairing with your device for the first time, do it at home.
  • Make sure you are always using the latest system software.

Bluetooth Safety Tips

If the two devices are relatively close together, they can pair, giving the hacker a chance to intervene. These are some Bluetooth safety tips that individuals should follow.

  • Turn off Bluetooth functionality when not in use
  • Do not accept pairing requests from unknown devices
  • Always make sure you are using the latest system software
  • Make sure the device you purchase has sufficient security features

Final Thoughts

Bluetooth is a popular feature in most modern devices. This is one reason why attackers are so keen to hack these devices. The five hacks he described above are just a few of the attack vectors I consider important, but there are definitely more vulnerabilities. If you pay close attention to each hack, the way to prevent each is pretty much the same.

Bluetooth products are used every day, such as connecting to car speakers and headsets. Therefore, educating individuals and companies about Bluetooth security is very important to prevent such attacks. If an attacker successfully gains access to your device, they can spy on communications and manipulate and steal sensitive information. Bluetooth attacks continue to occur via existing attacks or zero-day vulnerabilities. People rely on their mobile phones and tend to store all kinds of information on them. So do your part to prevent attackers from easily hacking into her Bluetooth device.
