Bluesnarfing: The theft of information form a wireless device through a Bluetooth connection. This allows access to a calendar, contact list, emails and text messages. Bluesnarfing is much more serious in relation to ‘Blue jacking’.

Bluecasting: Provision of any small digital media to suitable media provisioning enabled devices over Bluetooth via the OBEX protocol.

Bluebugging:

Blue bugging is a form of Bluetooth attack. Allows the user to take control of a victim’s

phone to call the user’s phone

Earlier issue:

Promotes an environment that puts consumer devices at greater risk. Complete memory contents of some mobile phones can be accessed

by a previously trusted paired device. Phonebook and calendar can be obtained without owner’s knowledge.

Present Scenario:

Primarily occurs in public spaces. Security issues previously involved with blue jacking has been resolved. In order for information to be duplicated, the devices would have to

be paired. Bluejacking does not require a password to be entered and therefore the two devices are not paired.

Control Measures:

Warning:

Turn off your Bluetooth device when not in use.

Never try to ‘hack’ a device. Is an offence under the “computer misuse act

1990”.

Conclusion

Blue jacking is a technique by which we can interact with new people.

It has ability to bring a revolution market by sending advertisement.
