This document summarizes a seminar on bluejacking presented by three students. Bluejacking involves sending unsolicited messages to Bluetooth-enabled devices. It can target devices like laptops, mobiles, and PDAs. The seminar covered how bluejacking works using Bluetooth technology and the OBEX protocol to transmit data within a limited range. It explained what is needed to bluejack others, such as a Bluetooth phone, and provided steps to search for and send messages to nearby devices. Potential uses of bluejacking, related concepts like bluesnarfing and bluebugging, and precautions were also outlined before concluding with references.

3. INTRODUCTION
• Bluejacking is the sending of unsolicited messages over
Bluetooth-enabled devices.
• Bluejacking do not remove or alter any data from the
device.
• The person who is being attacked does not know any
information about the hacker except the name assigned
to the hacker’s mobile phone.

4. BLUEJACKING CAN BE DONE IN DEVICES LIKE
LAPTOP
MOBILE
COMPUTER
PDA(personal digital assistant)

5. TECHNOLOGY USED
• BLUETOOTH TECHNOLOGY.
• OBEX protocol.

6. BLUETOOTH TECHNOLGY
• Short private area that uses radio frequencies to
transmit data.
• Has a very limited range , usually 10 meters on mobile
phones and around 100 meters on laptops.
• Connects various devices alike laptop, camera, mobile,
mouse, etc.

7. OBEX PROTOCOL
• OBEX (abbreviation of Object Exchange) is a communication
protocol that facilitates the exchange of binary objects between
devices.
• Helps to exchange business card, data, even applications.
• Initially OBEX was designed for infrared, latterly now has been
adopted by BLUETOOTH also used over USB.

8. Wanna try Bluejack? What do you Need?
• A BLUETOOTH enabled cell phone.
• A place with a lot of people having their BLUETOOTH
device switched on.
• Good sense of humor.

9. Search for a crowded place
e.g. mall, bus stand etc.
Put “on” your Bluetooth
Search for devices with active Bluetooth
…and enjoy the confused look.

10. Open keypad

Yesss !!

12. USAGE OF BLUEJACKING
• Advertisement
• Complimentary Messages
• Unethical usages

13. Where?
• Shopping mall
• Train station
• Cinema hall
• Café/ Pub
• Classroom

14. CODE OF ETHICS
• Do not hack any device.
• Do not send any abusive messages.
• Do not threaten anyone.
• Must not reveal yourself to the victim.

15. RELATED CONCEPTS
• BLUESNARFING
• BLUEBUGGING

16. BLUESNARFING
• Stealing of information from victim’s Bluetooth device
often between phone, laptops, PDA’s , etc.
• This allows access to a calendar, contact list, emails
and sms and moreover some user can steal even images
and private videos.

17. BLUEBUGGING
• Form of Bluetooth Attack.
• Allows user to take control of a victim’s phone to
call the user’s phone and can even send messages.
• Mechanism is being carried out using Laptop, with
the use of powerful PDAs and mobile devices.

18. MEASURES/PREVENTIONS
• TURN OFF BLUETOOTH device until when not
in use.
• Set the BLUETOOTH device to HIDDEN mode.

19. CONCLUSION
BLUEJACKING is a technique by which we can interact with
a new person and can bring a great change in the world of
advertisement by sending about the products, enterprises
etc. on the Bluetooth.
So we conclude that in future this technology becomes the
key for advertisement to interact with the world.
