Bluetooth technology may solve many of today’s connectivity problems – mostly having to use cables to connect system components. 

However, as with any new technology there are those who will try to exploit sometimes very complex and technical loopholes. 

One of the latest crazes amongst users of Bluetooth compatible mobile telephones is that of “Bluejacking”.  This is the “hijacking” of a random user’s mobile phone and sending anonymous, unsolicited text messages to them. 

It works because most Bluetooth compatible mobile phones will “search” for any Bluetooth devices which happen to be within range, which is approximately 10 metres.  The phone will usually list the devices it finds within range.  It is then possible to select one and send a text message to it.

Therefore, if you have a Bluetooth mobile phone, and you receive a mysterious text message, look carefully around you and see if you can spot who the mischievous sender is!

This craze is not really a serious breach of security of your mobile phone, but is perhaps an annoyance on a similar level to spam e-mail.

The craze is so widespread, it has spawned its own website, where you will find out more information about Bluejacking”:
