How many times of the day do you turn on BlueTooth on your phone? Probably a lot because your technologically advanced headphones can only be connected via Bluetooth. Every laptop, tablet, or mobile phone which works on the Android operating service has the BlueTooth wireless feature. It has made living a lot easier and wire-free. It can be used to transfer files, audio, images, connect devices, etc.
Hackers are always on the lookout for finding new ways to spy on people and gain satisfaction or, in some cases, money. Being people’s favourites, BlueTooth also caught the eyes of the hackers. Bluetooth hacking is the process of breaking the security of a Bluetooth device to gain unauthorized access. The Bluetooth devices are usually hacked by exploiting vulnerabilities in their software and then using them for malicious purposes. Due to the high incidents of hacking through BlueTooth, a new term “Bluebug” arose where the attack was through BlueTooth.
The process of hacking a Bluetooth device can be done by either using an application or through some methods. This article will discuss both the methods and provide some examples of how they are used in practice.
Methods of Hacking Through Bluetooth
Before going on to the methods, let’s first learn about the first and most important step. The first step is to identify the vulnerabilities and exploit them to gain unauthorized access. This can be done by identifying the vulnerabilities in the software, which is usually done by reverse engineering or fuzzing.
The next step is to create a connection with the target device and then use that connection for hacking the system.
BlueJacking
This approach only allows for one transmitter and one recipient of the information; using the bluejacking technique, information is transferred to a mobile device without the owner’s knowledge.
Initially, this form of Bluetooth intervention was only used to deliver text messages to one or more mobile phones at the same time. However, this has already changed. Today, harmful Trojan may send all types of information, including movies, photos, and even applications.
Bluejacking is commonly utilized for advertising campaigns on sites with a big number of visitors. However, it is also used to evade mobile phone security since a user who is continually flooded with messages may be enticed to open one of them.
BlueSnarfing
This paradigm extends well beyond Bluejacking. This allows information to be retrieved from another mobile device through Bluetooth without the intervening person being aware of it.
The only need for this mode to operate is that the Bluetooth of the spying device is detected by scanning it.
Almost everything of a mobile device’s information may be recovered with bluesnarfing, including messages, phone directories, images, movies, and documents. This approach is the most popular since it does not require you to operate the mobile device in order to spy.
BlueBugging
This approach is maybe the most comprehensive. It enables the execution of AT instructions on mobile devices. These instructions may change the whole settings of any mobile device, giving you complete control.
The hacker would be able to make a call, send texts, record conversations, and operate programs on the hijacked phone, among other things.
To make this work, the user being observed must approve the Bluetooth connection supplied by the hacker. This may be the lone barrier, but it may be avoided by employing techniques that drive the individual to accept your connection or give you the mobile to do it yourself. Once accomplished, there will be no turning back!
But how will the hacker make sure that the user connects their BlueTooth device to the hacker? This can be done by duplicating a similar public Bluetooth network that the user might have connected to in the past and could connect again with no scepticism.
There are some apps available too that make hacking through BlueTooth easier, these are BTCrawler, BTScanner, SuperBluetooth Hack 1.08, etc. These apps are authentic and can help you in figuring out how to hack with the help of BlueTooth.
Spying using Bluetooth communication technology is a prevalent current approach used by hackers, ranging from bluesnarfing to blue bugging.
However, you also have the ultimate surveillance gear in your hand and on your computer: a phone, tablet, and an appropriate application. You may also listen in on other people’s conversations using Bluetooth headphones or a smartphone.
Remember that eavesdropping on or obtaining data from some other device is illegal.
