It’s easier and more comfortable to enjoy this strands without wires – but until there, a hacker can change your life.
It is unlikely that there are readers who still need an explanation, but here is a summary definition of the bluetooth.
Bluetooth is a wireless communication technology that allows data exchange between electronic devices to short distances (up to 100 meters away, normally).
They are radio waves at specific frequencies – usually 2.4 GHz – with a pairing process for devices to recognize and communicate.
It came to replace cables, came to facilitate transfers, came to make life – even – easier for those in a mobile phone, a computer, or listening to music, among many other cases.
But this wireless freedom has a hidden cost, a “Black side” From Bluetooth, as NordVPN warns in a statement sent to ZAP.
The VPN service provider warns that this technology (too) is vulnerable because the simple and innocent to press a button can expose your device to hackers – even if they are at a distance from a soccer field.
When placing your device as detectable, Pirates can easily explore weaknesses and circumvent to the most advanced safety measures on the devices.
The most dangerous attack, the most obvious “dark side” of Bluetooth is the bluebugging: os hackers access the data and control the device. Fully.
Attackers can use the victim’s device to make calls, send messages, access the internet and even hear conversations, without the owner of the device noticing.
The most serious attacks occur when the hacker is 10 metrosor less of the device.
But the hacker may even be on the other side of a soccer field (there is, the maximum of 100 metros away) and can be able to access it.
In these longer distances, they occur bluesnarfing e bluejacking. In a bluesnarfing, the “pirate” steals information from a mobile phone, such as calendars, emails, text messages, photographs and videos. Bluejacking sends spam to a device, through unwanted messages or ads – but can also make international calls or so -called paid guys to the minute.
These attacks occur through mobile phones e computers, but also Domestic devices: Surveillance cameras, babies monitors, smart doors, televisions.
And in cars Also: hackers can hear their conversations in hands-free mode and even speak directly to people inside their car. And they just need a laptop and a Bluetooth antenna.
To avoid These crimes, it is best to disable Bluetooth when not using it, hide the visibility of Bluetooth, make Bluetooth devices undetectable, refuse unknown connection requests, create passage words for calls, be aware of peaks in data consumption And in general, always be aware of suspicious activities on your device.
