While Bluetooth is a convenient feature, it can also become handy for hackers to access your phone. Bluesnarfing is one way hackers take advantage of Bluetooth vulnerabilities.
Bluesnarfing is a hacking technique that exploits Bluetooth connections to snatch data from a wireless device. An attacker can perform bluesnarfing when the Bluetooth function is on and your device is discoverable by other devices within range. In some cases, attackers can even make calls from their victim’s phone.
Bluesnarfing is one of the most easily implementable types of hacking. Such data theft can occur without the user’s knowledge, and cybercriminals can obtain information such as emails, text messages, or contact lists. An attacker must be within at least 10 meters of you for an attack to succeed. However, in some cases, they can initiate a bluesnarfing attack from a greater distance.
To initiate a bluesnarfing attack, hackers must exploit the object exchange (OBEX) protocol used to exchange information between wireless devices. The inherent vulnerabilities of OBEX can be exploited by using such tools as Bluediving, which probes Bluetooth-compatible devices for OBEX loopholes.
After compromising the OBEX, hackers can pair their systems with a targeted device. Then they use bluesnarfing tools to attack it. If a device doesn’t have strong firmware protection, the attackers can snatch data from it.
Hackers either create bluesnarfing tools themselves or purchase them online. Ready-to-use tools are widely available on the dark web.
Here are a few tips on how you can reduce the possibility of a bluesnarfing attack:
