What is "bluejacking" and is it dangerous?
Within the computer security glossary, there's something called bluejacking. Bluejacking is when you take a Bluetooth device, most often a phone and it has something called a proximity sensor. A proximity sensor is something that sends a signal out and it picks up other Bluetooth signals that might be within that range, the 33-foot range. If it picks them up it identifies them on the screen of your device. Then, you can bluejack them. You can basically send them a message to their phone, send them a picture to their phone, and send them some kind of information to their phone that they're absolutely not expecting. This is not really dangerous though, bluejacking is actually kind of a popular thing in Europe, and in fact, there are bars in England where bluejacking is a very common practice, and people go there just to do that in a dating way. Bluetooth itself is a new technology that's a wireless technology that allows very short range connectivity between appliances without wires. It has a range of 33 feet, and this allows devices to talk to each other without wires, this could be a phone to a computer, another computer to a printer, or what have you.
