Interesting facts about bluetooth

Did you know that Bluetooth is translated from English as "blue tooth". And it was named so in honor of King Harald I or Harold Blue-tooth (norm. Harald Blåtand), who ruled Denmark and part of Norway in the 10th century and united the warring Danish tribes into a single kingdom. The implication is that Bluetooth does the same with communication protocols, combining them into one universal standard.

The Bluetooth logo is a combination of two Nordic ("Scandinavian") runes:

"Haglaz" (Hagall) - analogue of the Latin H

and "berkana" (Berkanan) - Latin B.

Thus, these symbols would be correctly translated as the royal initials of Harald Blåtand

The Bluetooth specification was developed by the Bluetooth Special Interest Group (Bluetooth SIG), which was founded in 1998. It includes Ericsson, IBM, Intel, Toshiba and Nokia. Subsequently, the Bluetooth SIG and IEEE reached an agreement on the basis of which the Bluetooth specification became part of the IEEE 802.15.1 standard.

Bluetooth allows these devices to communicate when they are within a radius of up to 100 meters from each other (range is highly dependent on obstacles and interference), even in different rooms.

There are two types of hacking attacks on a bluetooth device - passive and active. Both hacking procedures are quite complex and include several stages, the main of which is collecting data packets and analyzing them. The attacks themselves are based on vulnerabilities in the authentication mechanism and the creation of a cipher key between two devices.
