How Hackers Use Your Bluetooth to Steal Data

Given its capacity to enable users to connect their devices to speakers so that they can play music and transmit files from one user to another, Bluetooth is one of the most popular features on mobile phones.

The feature is present on practically all gadgets, particularly the ubiquitous cellphones of the modern era.

According to a report by the Communications Authority of Kenya (CA), which stated that there were 26 million cellphones in the nation as of December 2021, and millions of people in Kenya have access to Bluetooth.

However, because of its accessibility, users are now more vulnerable because some frequently forget to turn it off, giving hackers access to their private data.

Here are ways hackers use Bluetooth to steal personal data:

Bluesnarfing

Hackers can now access data stored on phones, including images, messages, documents, and other items, by forcing a connection to a Bluetooth device.

Additionally, by gaining access to the International Mobile Equipment Identity, hackers can direct all phone calls and texts to their devices (IMEI).

Most frequently, hackers extort their victims using this information.

In order to gain access to a phone, hackers can also create a backdoor over Bluetooth.

Through the connection, they may be able to spy on their targets by, among other things, reading emails, making phone calls, and listening to calls.

Hackers can utilize blue bugging to track financial transactions as mobile banking usage rises, putting users at risk of fraud.

Bluejacking

Bluejacking is the practice of sending spam messages to mobile devices, and if the recipient clicks on the link, the hacker gains access to the device and its contents.

Therefore, when your Bluetooth is connected to another device, it is advised to disregard unsolicited messages.

Other frequent attacks include “car whispers,” in which IT experts manipulate an automobile’s audio system to play an audio file.

The best way for users to guard against such situations is to turn off their Bluetooth when not in use, disable Bluetooth discovery in the settings, avoid connecting in public, and other measures.
