Bluejacking – Fact or Fiction
posted December 15th, 2008 by GregBluetooth software, now commonplace in virtually all mobile phones, was a revolutionary and welcomed addition to mobile phone connectivity. Mobile phone users are now able to send pictures, videos and other files in a wireless connection using radio frequencies to establish the transfer. This enabled widespread sharing of photo albums, ringtones and other media with the best thing being – it was free. However, as history seems to prove, with every useful technological advancement there is a group of people developing ways in which to exploit and abuse it.
The main form of these exploits is Bluejacking which is essentially the sending of unwanted or unsolicited media or files via Bluetooth. You may have experienced receiving a message or alert on your mobile phone whilst out in a busy pub or shopping centre. It is unwise to accept these types of messages as there is no guarantee that they are from a safe or secure source. Allowing messages or files like these to be transferred to your mobile can often lead to further unwanted junk messages and it can prove difficult to stop them. Bluejacking has even been used in aggressive advertisement campaigns by some mobile game developers and other independent companies. What is most worrying about Bluejacking is that, although not commonplace yet, there have been instances of mobile phone users receiving viruses and other harmful software via an unknown source.
How do I protect my mobile phone, I hear you cry? Simple. Only have the Bluetooth function of your mobile phone switched on, when transferring or receiving files. That way, no third party or other source can access or try to Bluejack your mobile phone whilst not using it. Remember only accept files from a known sender, with any unidentifiable source simply choose to reject or decline the file. With most mobile phone models it is also possible to enhance the security of your Bluetooth connection by adding a password, or PIN number that must be entered by both parties when sending or receiving file
