Seminar On Cellular Virus

1. Seminar OnCellular Virus

2. INTRODUCTION • Viruses in the cell-phone arena are new but there are many parallel between computer and mobile phones in terms of mallicious code. • The first cell-phone viruse been sited is CABIR-A. • CABIR-A is a virus written specially for Nokia Series 60 mobile phones running on the Symbian operating system. • The virus spreads as a .sis package,named as Caribe.sis. • This topic will discuss the virus affecting the cellular phones and what all remedies can be taken to overcome this problem.

3. VIRUS • It is a computer program that is designed to replicate itself by copying itself into other programs. • Mobile Virus-It is an electronic virus that targets mobile phones.

4. HISTORY • The first instance of a mobile virus occurred in August 2004. • In July 2004, computer scientists released a proof-of-concept mobile virus named Cabir . • In March 2005 it was reported that a computer worm called Commwarrior-A has been infecting Symbian series 60 mobile phones.

5. COMMON MOBILE VIRUSES • CABIR- Infects mobile phones running on Symbian OS. • DUTS -A parasitic file infector virus and is the first known virus for the PocketPC platform. • SKULLS- A trojan horse piece of code. Once downloaded, the virus, called Skulls, replaces all phone desktop icons with images of a skull. • COMWARR- First worm to use MMS messages in order to spread to other devices .

6. MOTIVE TO CREATE VIRUS • Challenge • Some antivirus companies want to enter new market • To gain wider attention

7. VIRUS ACTION • Damage by deleting or modifying the phone book. • Starting to make phone calls to pay-per- minute numbers . • Send SMS text messages to all the numbers found within cell phone.

8. SPREADING VECTORS • Bluetooth • MMS • Web downloads • Memory cards

9. WAP SECUIRITY PROBLEM • WAP gateway security • Operating system • Use of SMS

10. WAP GATEWAY SECURITY

11. SYMBIAN OPERATING SYSTEM • It is mainly designed for mobile devices. • It has associated libraries,user interface frameworks and reference implimeatations.

12. CURRENT THREAT CABIR Symb/Cabir-A is a virus written specifically for N-Gage, 3650, or other Nokia Series 60 mobile phones running in the Symbian operating system. The virus spreads as a .sis package, named as Caribe.sis.

13. CABIR REQUIRES • Approving receiving a file from unknown device. • Approving receiving a application from unknown device. • Approving connections from unknown devices.

14. REASONS TO CREATE CABIR There are two reasons behind Cabir creators • Some antivirus companies want to enter new market. • May be Microsoft wants to show how insecure Symbian OS is compared to their MS Smart phone.

15. WORKING OF CABIR When launched, the worm displays a message on the screen: either 'Caribe' or 'Caribe - VZ/29a' . worm itself is an SIS format file, called caribe.sis, of 15092 or 15104 bytes in size . This file contains three objects: • caribe.app: 11932 / 11944 bytes in size • flo.mdl: 2544 bytes in size • caribe.rsc: 44 bytes in size

16. PRECAUTIONS • IF is your bluetooth on and you are receiving file be REALLY careful . • Never download cell phone applications from file sharing networks . • NEVER install any UNEXPECTED application received by MMS message from ANY senders (including your friends!). • Accustom yourself to disable bluetooth if you don't use it .

17. CONCLUSION • Virus can not install & it can’t run without user’s knowledge & conscious acceptance. • Virus can be avoided by taking precautions.
