Police warn against always having your cell phone's Bluetooth on: "They only need to be within 10 meters of you to rob you."

Bluetooth has become a tool we use practically every day to connect to different devices such as headphones or speakers, and although activating and deactivating it is as simple as pressing a button, the vast majority of users choose to always have it on.

And while many people may believe that this only affects our battery, which nowadays barely contributes to its drain, having the mobile phone's Bluetooth on all day carries an unknown danger for many.

This is the warning issued by the National Police, who, through a video published on their TikTok profile, explained what Bluesnarfing is and what you can do to avoid it . While they point out that having it always on at home doesn't usually pose a threat to our cybersecurity, we should be more careful when we go out.

This type of cyberattack uses Bluetooth to access victims' devices and steal their personal and banking information . Today, the vast majority of devices, such as smartphones, tablets, computers, smartwatches, and headphones, have this wireless connection, so the threat is very real.

And while it's true that, as a general rule, you have to provide authorization to establish a Bluetooth connection between devices, cybercriminals have programs that bypass this consent and connect directly to your device without you even noticing. Once they do, they have access to any content or information you have stored on your device.

The first and most effective measure against this type of attack is to keep your Bluetooth connection off whenever you don't need it . It's true that users tend to always have it connected with smartwatches or wireless headphones, but for these cases, there's the option to hide your connection from others.

At the same time, you should keep in mind that you should never authorize connection or pairing with unknown devices and you should always try to have the latest software update for your device, as these correct existing weaknesses and increase the security of our devices.
