What is BlueJacking?

The phrase BlueJacking is attributed to Ajack - a member of the Esato boards who 'discovered' it back in December 2002.

In order to understand BlueJacking you need to understand Bluetooth.

Bluetooth technology is an open specification that enables short-range wireless connections between devices (a device can be almost anything such as a desktop or laptop computers, PDAs, mobile phones, camera phones, printers, digital cameras, keyboards and even a computer mouse). Bluetooth wireless technology uses a globally available frequency band (2.4GHz) for worldwide compatibility. In a nutshell, Bluetooth technology enables your digital peripherals to talk to each other without needing wires and cables.

Being an 'open specification' means that any manufacturer can make a Bluetooth device and it will talk to any other Bluetooth device from any other manufacturer.

Due to the very high frequency (2.4 Ghz) and very low power used, Bluetooth devices are only designed to operate over short ranges - typically less than 10m (30 feet).

OK, so now you understand Bluetooth

BlueJacking is a new term used to define the activity of sending anonymous messages to other Bluetooth equipped devices (typically PDAs and Mobile Phones) in range of the senders device. Whilst the ability to receive such messages can be disabled or the Bluetooth functionality of the device can be switched off, the fun nature of BlueJacking is likely to encourage people to paticipate and to enjoy the new phenomenen.

It is important to point out at this point that it is vitually impossible to catch a 'virus' from BlueJacking and no damage can occur to your phone or PDA (they cannot read your email or access your data via BlueJacking). However please read the Etiquette page and remember that if you send abusive or dafamatory messages you leave yourself liable to prosecution!

Can I BlueJack?

Firstly you need to have a BlueTooth enabled Mobile Phone or PDA - if you have then great, if not then you will not be able to enjoy the world of BlueJacking - sorry.

Assuming you have a Bluetooth enabled device then read the How To page to discover how to start BlueJacking.
