What is Bluejacking?

The term bluejacking refers to an attack that would endanger the proper functioning of a connection. Bluetooth, It basically means that one person, an intruder, is going to be able to send a message using this wireless network technology to another person without their consent.

If your device is compatible with Bluetooth, it is active and also in range of someone else who would be an attacker, you could be a victim of bluejacking. The attacker will locate that computer and can send a message to the victim. What it does is exploit the function that this technology has and which allows a device to send a message as long as it is in range.

Keep in mind that bluetooth works normally here 10-15 metros, Plus, it’s difficult for them to work, so don’t expect anyone to attack you when you’re at home, as it would be very rare for them to have access to your device. But this is more common in crowded places, such as shopping centers, for example.

Therefore, the fact of bluejacking is that send unauthorized messages via bluetooth. For example, an intruder can send it to our mobile. This also includes pictures or files. Furthermore, these messages would remain anonymous as only the device model and name the attacker wanted to give would be shown. It won’t show phone numbers, or any personal data.

It is usually a harmless attack

Is this really a major security attack? the truth is that it’s usually a harmless attack, Unlike other problems that we can suffer from with Bluetooth, Wi-Fi networks and our devices in general, this is not a threat that itself can pose a significant problem to security and privacy.

At the end of the day, what a potential intruder is going to do is send a message, We’re going to look at the content that he sends to the phone, but nothing more. It is not entering our mobile, nor is it malware or password stealing as it can be with a phishing attack by email or SMS, for example.

Although more complex than other attacks, with this method a potential intruder can send us a message prompting us to do something that threatens our security and privacy. For example, inviting us to access a web page that is actually fraudulent. Also, through the image you send us, it may contain some text that, likewise, invites us to enter a site that is actually a fraud.

This is when we enter a malicious page where they can steal our data and compromise the security of the system. For example if we download a malicious file or if we enter any personal data.

What to do to avoid this?

How can we avoid becoming a victim of bluejacking? While this is usually something harmless and doesn’t pose any real security issues, it’s important to keep a few tips in mind to avoid receiving messages that we don’t want. At least to avoid the potential annoyances it would cause.

turn off bluetooth when not in use

the first trick is don’t keep bluetooth on beyond what is necessary. It is a technology that we can use to link headphones, exchange files with other devices, etc. But once we have stopped using it, it is not so good to keep it always on, because it will be available to anyone.

Therefore, we recommend lock it up And only turn it on if you’re actually going to use it. In addition, this will also help in saving battery power. If you have it, it will continue to send and receive data as it searches for possible devices to sync.

Keep in mind that many current mobiles are already configured by default to turn off Bluetooth as a time passes. This helps to prevent bluejacking attack and also other serious issues that can affect the device without our knowledge.

Beware the Text We Receive

Have you received a text message via Bluetooth and you really don’t know who sent it? Be careful and analyze it thoroughly. Maybe you just received it by mistake, for example if someone sent it thinking it was someone else’s device. but it can be a Net,

Beyond the annoyance, that message may contain a text inviting you to enter a web page that would pose a significant security issue. Never visit websites or download files that may invite you to download them. In such a situation, they can put your safety at risk.

Always update device

to keep device updated is always important. This is not only to avoid safety problems, but also to ensure optimum operation. Therefore, another recommendation is to always update the device you use via Bluetooth as well as the drivers.

This will help to fix some vulnerabilities that can be exploited, not only for bluejacking attack but also for many other techniques that can be used against you without realizing it and that can be a very serious problem. Is.

In short, as you saw, bluejacking is a technique in which they use bluetooth to send messages anonymously to a device. It can be sent by anyone as long as they are within range of the signal, which is usually no more than a few tens of meters. While this is not a very serious security issue, like other attacks, it is advisable to take precautions and thus avoid compromising our data.
