What Is Bluejacking and How to Avoid Bluejacking Attacks
Over the recent years, infrared technology has been replaced by Bluetooth for file sharing and other means of communication. Over the years, this technology has also been superseded by Wi-Fi with multiple use cases. Currently, nearly every smart device comes with Bluetooth functionality, which is why understanding the risks of bluejacking is important. As a mild form of cyberattack, Bluejacking is executed only on Bluetooth-enabled devices. It could be both annoyingly harmless and malicious, depending on the nature of cybercrime.
We’ll explain how bluejacking a phone is common nowadays and how to avoid bluejacking attacks by securing your device.
What is Bluejacking?
The term was introduced in 2000 when some mobile phone users exploited the Bluetooth functionality by sending random messages to phones nearby. Although meant for pranks at first, bluejacking now has serious implications for your cybersecurity.
How Bluejacking Works?
An attempt at Bluejacking involves the following steps:
- Activate Bluetooth on your device and set it to “Discoverable” mode.
- Scan nearby devices, cybercriminals do this perpetually to find nearby Bluetooth-enabled devices.
- Sending a message via the contact-sharing option, in some devices, can be done by different names.
- The target receives the message, which appears to be coming from a legitimate source.
What most people don’t understand is bluejacking, bluebugging and bluesnarfing and different. With bluejacking, you will not be subjected to data theft or device control. It only sends a message for different case scenarios.
A Big Question: How to Prevent Bluejacking Attacks
It’s easy to avoid or prevent bluejacking attacks; let us show you how you can protect yourself from this:
- Turn off your Bluetooth while you are not using this functionality. It will prevent your device from connecting to others.
- Upon turning on the device’s Bluetooth, make sure to use Hidden or Non-Discoverable Mode. This way, you can only access your Bluetooth to connect earbuds or other devices.
- Do not accept unknown Bluetooth requests unless you know the sender.
- You can check the active connections on your Bluetooth settings. Any unknown device shall be disconnected and removed.
- Use security apps (VPN) or your device’s built-in security features, which will detect and block the unwanted Bluetooth connections. With a VPN, you can add a whole concrete layer of protection on your device.
Difference between Bluejacking, Bluebugging, and Bluetoothsnarfing
The following table will help you understand the difference between bluejacking, bluebugging, and bluesnarfing in 2025:
| Name | Key Function | Access to Data | Risk Level |
|---|---|---|---|
| Bluejacking | Sends unsolicited Bluetooth messages | Does not access or extract user data | Commonly used for pranks or spam; annoying but less harmful |
| Bluebugging | Gain remote control over a device | Grants access to calls, messages, and more | Highly intrusive; attackers can control core device functions |
| Bluesnarfing | Connects secretly to extract information | Steals contacts, messages, emails, etc. | Serious data breach; exploits weaknesses in Bluetooth security |
Security Level on Bluetooth Latest Version
With Bluetooth 5.0 running on major devices and 6.0 on the way, you can count on the slightly firmer security protocols, which make Bluejacking less common nowadays. However, different methods of cyberintrusion are being introduced each day, with many more Bluetooth-based attacks on the way.
Our Smart TV, smartwatches, earbuds, and various home appliances run on Bluetooth technology; if not properly secured, they can be vulnerable to what we described above. Although deemed harmless, Bluejacking proves that our security habits need to be altered with the fast-paced digitalized world.
Conclusion – Don’t Mistake Bluejacking for the Real Threats
Bluejacking is a mere reminder of how our devices are prone to emerging cyberattacks, especially when we are not connected to our home network. Cyber pranks like bluejacking cannot steal your data, but they can divert you to much greater risks, such as phishing attacks, malicious ads, and the dangers of public Wi-Fi.
You can count on VPNs that help with cybersecurity! Top-notch VPNs like Ivacy VPN may not be useful in combating bluejacking since they are insignificant, but they protect you against web trackers and hacking attempts and encrypt the connection on public networks. Avoiding the risks of bluejacking can be done simply by following simpler tips, whereas you can handle the bigger picture with real professionals.
