Experts warn against leaving your phone’s Bluetooth on 24/7

Introduced all the way back in 1998, Bluetooth technology is a simple way to wirelessly exchange data over short distances. 

It’s got several applications, including being used to connect wireless headphones and speakers, or to hook your iPhone up to Apple CarPlay.

However, experts have warned that it’s not a good idea to leave your connection open if it’s not actually in use. 

According to BGR, Bluetooth technology can be hit by ‘bluejacking’ or ‘bluesnarfing’. 

Bluejacking is when a stranger uses a Bluetooth connection to send unauthorized information to a Bluetooth-enabled device – i.e., your phone. 

Whereas bluesnarfing is more nefarious and can involve manipulating your connection in an attempt to obtain data from a Bluetooth-enabled device – i.e., yep, you guessed it, your phone. 

Hackers are also able to use your phone’s Bluetooth signal to track your location and, in certain circumstances, access apps and services on your phone that collect your location information. 

As the tech’s detection range is pretty small, hackers would need to be in close proximity to you and your device to use either bluesnarfing or bluejacking, but while this may seem reassuring, it doesn’t mean you’re safe. 

In 2017, a Bluetooth exploit known as BlueBorne was identified by tech experts, and a serious warning was issued that billions of devices, including phones, laptops, and tablets, were at risk.

How can you keep safe?

Although the risks are there, it’s relatively simple and straightforward to keep your devices and information safe. 

Firstly, toggle your Bluetooth connection off when not in use, and only fire it back up when you need it. 

You can also set up two-factor authentication, also known as 2FA, for any apps or services that have Bluetooth features built into them. 

It’s also important to check that your phone and other devices are running the latest version of their operating systems, so that you have any necessary patches and security fixes.
