The widespread use of wireless networks has led to problems with information security. Getting access to poorly protected Bluetooth devices and intercepting information transmitted via radio channels is sometimes quite easy. Today, it is enough to go to any cafe and launch a search for active Bluetooth devices, and there are likely to be two or three smartphones with the embedded technology. They will be open to access to all the files and services without any password. The issue of Bluetooth security is rather important to discuss and develop since it allows revealing potential ways to protect users’ personal data and increasing their awareness of the need to ensure security during connections. Even though Bluetooth is designed to organize communication between devices at a distance of no more than 10-15 meters, many portable Bluetooth-enabled mobile devices are used around the world. Users often visit places with a lot of people, so some devices accidentally end up in close proximity to others (Panse & Kapoor, 2012). In addition, the majority of such devices are configured not carefully enough, and people leave the default settings, making information vulnerable to interception. Thus, the weakest point in Bluetooth technology is a user. Namely, people with Bluetooth smartphone devices as well as companies that use this technology to transmit sensitive information are the key interested parties. At the same time, people who are particularly conscious about their security may also benefit from discussing this topic. All of the mentioned categories of people need effective ways to protect their devices. There are three key routes through which Bluetooth may be hacked, including bluejacking, bluebugging, and bluesnarfing. As stated by Pandey and Khara (2017), bluejacking refers to sending anonymous messages through the hacked device with the aim of fraud or any other illegal action. The above way of hacking usually occurs in large shops where there a lot of people with Bluetooth turned devices (Pandey & Khara, 2017). Via bluebugging, hackers obtain control over a victim’s smartphone and execute commands. For example, the identified researchers note that they may call, send messages, and even view the list of calls to the given device. In other words, almost total control is taken over a victim’s device. The third way of hacking via Bluetooth allows accessing a person’s email, contacts, and other areas that contain sensitive information. It remains unnoticed for a victim, while a hacker transfers information to his or her own device. More than half of the users of mobile phones or laptops with Bluetooth are not familiar with methods of protecting devices from the penetration of malicious programs via Bluetooth (Pandey & Khara, 2017). Even those devices that are turned to a hidden mode may be vulnerable to attacks since hackers may suggest their MAC address. In addition, Pandey and Khara (2017) emphasize that due to some features of old mobile devices, it is possible to remotely switch Bluetooth from the hidden mode to general accessibility without notifying the user of the device. Once a smartphone was susceptible, hackers may code and compile a tool for attacks or use some existing snippets. Thus, it becomes evident that victims even do not understand that their device was hacked. The preventative measur
