Bluesnarfing

Bluesnarfing is a type of wireless security attack employed by hackers which uses Bluetooth technology to gain unauthorized access to data and devices. It is a type of infiltrating attack that originates from the personal computing environment. The term ‘bluesnarfing’ is derived from the expression ‘bluejacking’, which is a legitimate activity used to send anonymous messages to mobile phones over an Bluetooth connection.

Unlike bluejacking, which can be as simple as sending anonymous text messages, bluesnarfing takes advantage of security flaws in Bluetooth-enabled devices. This can allow a malicious attacker to get access to a victim’s data or, if certain security levels are enabled, gain copying rights and extend control over the device.

Unlike attacks that use Wi-Fi or other radiofrequency networks, bluesnarfing focuses on devices that reside in close proximity to the target. An attacker typically uses a wireless device, such as a laptop or cell phone, to scan for vulnerable Bluetooth-enabled devices. The device can then connect to the target, enabling the hacker to manipulate the data or send unsolicited files, and potentially disrupt the service.

Bluesnarfing has become a major problem for any user of Bluetooth-equipped devices. To protect against such attacks, users should employ strong passwords and establish a secure connection between devices. In addition, most device owners should activate their Bluetooth only when necessary, and disable it the rest of the time.
