As Bluetooth technology gets smarter, so do hi-tech hackers. The best defense against becoming a victim of online identity theft is to educate yourself on the latest trends targeting Bluetooth-enabled devices, and as a result, do what you can to help keep thieves away from your hands-free connection.
Bluejacking, Bluesnarfing, Bluebugging—What’s the Difference?
BLUEJACKING
Think of it as a high-tech version of ding-dong-ditch, where savvy pranksters push unsolicited messages to engage or annoy other nearby Bluetooth users by taking advantage of a loophole in the technology’s messaging options.
BLUESNARFING
More damaging than bluejacking is bluesnarfing. With bluesnarfing, thieves wirelessly connect to some early Bluetooth-enabled mobile devices without the owner’s knowledge to download and/or alter phonebooks, calendars or worse.
BLUEBUGGING
Bluebugging goes beyond bluejacking or bluesnarfing, allowing thieves to take full control of a device. A crafty bluebugger can wirelessly direct a mobile phone to make calls without the owner’s knowledge. Similarly, a bluebugger can set call forwarding and receive calls intended for the unsuspecting victim.
How to Safeguard Your Devices
UPDATE YOUR DEVICES
Early Bluetooth-enabled devices defaulted to “discoverable” mode, leave connections vulnerable. This loophole has since been corrected in newer devices. If you’re using an older device, connect by using the “non-discoverable” mode (usually a menu option on your device). This is especially important when you’re in an unfamiliar hot-spot area.
BE HANDS ON
Limit use of your hands-free connection, especially when you are exchanging sensitive data.
BE AWARE OF STRANGER DANGER
Criminals use unsolicited messages or business cards to try and engage victims within range. Don’t engage if you see a strange message like: “I like your hat” or “Enjoying your meal?” Delete!
MONITOR YOUR DATA USAGE
Know your average data usage. If you see a spike, it could be a sign that a hacker is using your device remotely.
LOOK FOR SUSPICIOUS ACTIVITY
If your device starts behaving unexpectedly—turning off or on, or suddenly disconnecting and then reconnecting—it may be a sign you’ve been hacked. If you suspect this is the case, reset your device to factory settings. This is usually a “settings” option on your device that will erase all data and applications, including those that have been criminally installed.

What is bluesnarfing and bluejacking? ›
Bluesnarfing is way more pernicious and differs from Bluejacking in that, rather than send messages to the victim, it aims to steal content from the victim. These attacks aim to manipulate the connection to steal sensitive data like photos, passwords, contacts, and such. Unlike Bluejacking, Bluesnarfing is insidious.
What is the difference between a bluejacking and a bluesnarfing attack quizlet? ›
Bluejacking looks for nearby devices that are in discovery mode and sends unwanted messages whereas Bluesnarfing exploits a vulnerability in the object exchange (OBEX) protocol that allows an attacker to pair to the target device.
What is an example of a bluejacking attack? ›
An example of bluejacking is when you receive a random message from an unknown sender while using a Bluetooth-enabled device, likely while in a public place. The message may urge you to follow a link for important information.
Is bluesnarfing illegal? ›
Bluesnarfing is illegal in many jurisdictions and can have a life-changing impact on the owner of the target device. Possible consequences of falling victim to bluesnarfing include data theft, financial fraud, and identity theft.
What are the signs of bluebugging? ›
Some signs of a bluebugging attack can include erratic or unexpected device behavior, drained battery life, unknown Bluetooth connections, and unusual call or message history on your device. These signs may indicate unauthorized access to your device.
Can someone spy through Bluetooth? ›
Criminals can exploit Bluetooth in your mobile phone and install malware, even when it's switched off. Steal data being transmitted over Bluetooth. Hackers can still capture data being sent over a Bluetooth connection, even if the data is encrypted.

What is bluebugging in cyber security? ›
Bluebugging is a hacking technique that allows individuals to access a device with a discoverable Bluetooth connection.

The hacker can read and send messages, access the victim's phonebook, and initiate or eavesdrop on phone calls.
What are the disadvantages of bluejacking? ›
Disadvantages
