Seminar On Cellular Virus

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.

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.

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.

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 .

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

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.

SPREADING VECTORS Bluetooth MMS Web downloads Memory cards

WAP SECUIRITY PROBLEM WAP gateway security Operating system Use of SMS

WAP GATEWAY SECURITY

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

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.

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

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.

WORKING OF CABIR caribe.app: 11932 / 11944 bytes in size 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

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 .

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