Technological devices are made to improve convenience with each upgrade. Unfortunately, more convenience can come with more risk. For example, users look for features such as Bluetooth connectivity when shopping for laptops, phones, smartwatches, etc. Businesses also look for similar features to make it easier for employees to stay connected. the Bluetooth feature increases risk for a cybersecurity attack: Bluesnarfing.

How It Works

Bluesnarfing is the theft of information from a wireless device through the use of Bluetooth connection. Bluetooth is a wireless technology that allows rapid exchange of information within a close physical distance. Hackers are able to tap into this technology without being detected as far as 300 feet from a Bluetooth device. They attack devices that are most vulnerable such as devices that always have Bluetooth "on" or devices that are left in "discovery" mode.

What's at Risk?

When a hacker has successfully compromised a device, all data is at risk. This includes photos, contacts, emails, passwords, and more. In addition to accessing data, this also poses the risk of increased phone bills due to hackers tapping into your device to make long distance calls. 

Preventative Measures

In order to prevent Bluesnarfing, you can adjust the settings on your device accordingly. You can switch your device to "non-discovery" mode as the first step. Next, you can reduce the chances of hacking your pin by making it at least 8 digits long as every additional digit increases the amount of combinations by 10,000 to crack it. Never accept pairings from unknown devices and try to keep pairing and Bluetooth off in crowded areas. Also, turn off Bluetooth when not in use. 

Whether you're concerned about personal devices or workplace devices, the same preventative measures and precautions should be taken. For more information about preventing Bluesnarfing, reach out to us here and a CPI representative will contact you.
