Bluejacking is a particular way to abuse the BlueTooth feature that many modern mobile phones have, and the fact that most people don't understand the technology that they own and carry around with them everywhere.
To Bluejack someone a message is sent from your BlueTooth mobile phone to theirs. Because of the nature of BlueTooth you can send to any BlueTooth enabled phone within range (which varies from a couple of metres to up to 20 metres or more, depending on the phones involved and the environment - clear line of slight gives a longer range), and most phones will display the message without giving the owner an option to reject it.
Why Bluejack?
Bluejacking is an excellent way of shaking someone out of their otherwise boring and mundane rut. It can be used to great effect during
commuter hell when everyone is locked inside their own heads. Particularly random or unexpected messages, like 'You Are Beautiful' or 'I hate being your phone', can have an extreme effects.
Bluejacking is also useful in making people aware of the technology that they surround themselves with, but which the majority do not understand. Making them aware of their ignorance can sometimes bring on a minor illumination, and may even cause a person to decide to stop buying into the mobile phone upgrade scam and stick with what they have - or even do without.
How to Bluejack
Bluejacking exploits a feature in the majority of BlueTooth enabled devices which can receive address book/business card information. Most devices (mobile phones, PDAs, computers) display the name of the address book entry on the screen when receiving it, and ask if the user wants to keep the data. By making an address book entry where the 'name' field contains the message you can cause it to appear on the target's screen. As most people with BlueTooth mobile phones know little to nothing about BlueTooth or the features of their phone they don't realise what the message is - many think that it's actually some form of SMS text message.
How to Bluejack: Sony-Ericsson phones
- Make your address book entry in the normal manner, placing your message in the 'name' field. You do not need to store a number with the entry, and may wish to add a space to the start of the message to separate your Bluejacking address book entries from your normal ones.
- While in a suitable location, press the selection joystick down to activate the address book and navigate to the message you wish to send.
- Use the right button to activate the menu for that address book entry and select 'Send'.
- Select 'BlueTooth' and wait while the phone scans the area for available devices.
- Select a target from the list - you do not need to wait until the scan is complete before selecting.
- The phone will attempt to send the address book entry to your target. Sometimes this will fail - it is rarely worth trying again, so select 'no' when asked.
Good Bluejacking locations
Good Bluejacking locations are places where there's lots of people, particularly places where there's lots of people likely to be caught by the mobile phone upgrade scam, and the rich-but-ignorant middle-classes.
Some suggestions:
- Most university campuses, particularly richer universities and social science/non-geeky areas.
- George Square at Edinburgh University is the obvious example of this type of place, and if you hang around outside during class changes and lunch you can catch many people.
- Shopping areas with more upmarket and trendy shops.
- In Edinburgh Princes Street is an obvious one, but one of the best places in the city to find Bluejacking targets is IKEA.
- Nightclubs and pubs.
- Public transport during commuter hell.
