What is Bluejacking?
Bluejacking allows phone users to send business cards anonymously to one another using Bluetooth technology. Bluejacking does NOT involve any altercations to your phone's data. These business cards usually consist of some clever message or joke. Bluejackers are simply looking for a reaction from the recipient. To ignore bluejackers, simply reject the business card, or if you want to avoid them entirely, set your phone to non-discoverable mode.
What is Bluesnarfing
Bluesnarfing refers to a hacker who has gained access to data, which is stored on a Bluetooth enabled phone. Bluesnarfing allows the hacker to make phone calls, send and receive text messages, read and write phonebook contacts, eavesdrop on phone conversations, and connect to the Internet. The good news is, bluesnarfing requires advanced equipment and expertise or requires the hacker to be within a 30 ft. range. If your phone is in non-discoverable mode, it becomes significantly more difficult for hackers to bluesnarf your phone. According to the Bluetooth SIG, only some older Bluetooth enabled phones are vunerable to bluesnarfing.
What is Bluebugging?
Bluebugging refers to a skilled hacker who has accessed a cell phone's commands using Bluetooth technology without the owner's permission or knowledge. Bluebugging allows the hacker to make phone calls, send messages, read and write contacts and calendar events, eavesdrop on phone conversations, and connect to the Internet. Just like all Bluetooth attacks, the hacker must be within a 30 ft. range. Bluebugging and bluesnarfing are separate security issues, and phones that are vulnerable to one are not necessarily vulnerable to the other.
What are Phone Manufacturers Doing to Solve These Problems?
Two of the leading cell phone manufacturers, Nokia and Sony Ericsson, have developed software patches for phones susceptible to bluesnarfing and bluebugging. Also, both manufacturers have taken great measures to ensure new phones entering the market will not be susceptible to these attacks.
Are There Any Other Threats With Bluetooth Technology?
According to the Bluetooth SIG, bluesnarfing and bluebugging are the only known security threats. However, as Bluetooth technology continues to expand and develop, the Bluetooth SIG is constantly researching security risks that may arise.
What Can Users Do to Protect Their Data?
There are several measures users can take in order to protect their device’s information:
- If a phone is vulnerable to bluesnarfing or bluebugging--contact the manufacturer or take the phone to a manufacturer-authorized dealer. There are software patches available for many older Bluetooth phones.
- Turn the device to non-discoverable mode when not using Bluetooth technology.
- Never pair with unknown devices or in public places.
- When possible, use an eight character or more alphanumeric PIN.
