Mobile Virus

Mobile virus
A mobile virus is an electronic virus that targets mobile phones or wireless-enabled Pads.
As wireless phone and PDA networks become more numerous and more complex, it has become more difficult to secure them against electronic attacks in the form of viruses or other malicious software
History
The first instance of a mobile virus occurred in June 2004 when it was discovered that a company called Ojam had engineered an anti-piracy Trojan virus in older versions of their mobile phone game Mosquito. This virus sent SMS text messages to the company without the user's knowledge. This virus was removed from more recent versions of the game; however it still exists on older, unlicensed versions. These older versions may still be distributed on file-sharing networks and free software download web sites.
In July 2004, computer hobbyists released a proof-of-concept mobile virus named Cabir. This virus replicates itself on Bluetooth wireless networks.
In March 2005 it was reported that a computer worm called Commwarrior-A has been infecting Symbian series 60 mobile phones. This worm replicates itself through the phone's Multimedia Messaging System (MMS). It sends copies of itself to other phone owners listed in the phone user's address book. Although the worm is not considered harmful, experts agree that it heralds a new age of electronic attacks on mobile phones.
Common mobile viruses
Cabir: Infects mobile phones running on Symbian OS. When a phone is infected, the message 'Caribe' is displayed on the phone's display and is displayed every time the phone is turned on. The worm then attempts to spread to other phones in the area using wireless Bluetooth signals.
Duts: A parasitic file infecter virus and is the first known virus for the PocketPC platform. It attempts to infect all EXE files in the current directory (infects files that are bigger than 4096 bytes)
Skulls: A trojan horse piece of code. Once downloaded, the virus, called Skulls, replaces all phone desktop icons with images of a skull. It also will render all phone applications, including SMSes and MMSes useless
Commwarrior: First worm to use MMS messages in order to spread to other devices. Can spread through Bluetooth as well. It infects devices running under OS Symbian Series 60. The executable worm file once launched hunts for accessible Bluetooth devices and sends the infected files under a random name to various devices.

It's important for all mobile user who loss there mobile with there mobile data.By backing up data you get your data after or before loss your mobile.

There are following pointes must keep in mind at the time of Backing up data:

* Will you be doing backups while on the road or from your home office only.

* How easy to use is the backup solution?

Methods for Back up

*software programs-There are many softwares are available for back up. all the mobile have there own Back up software.by using those software you get your mobile data back up.

*Disk Cloning-this method involves copying an entire hard drive to another source such as an external hard drive, CD, DVD or second hard drive.

There are plenty of free email services available which offer large storage amounts, which are useful for this method.

Backup Media

Choosing which media to use for your backup is another decision based on you.The following types of media available are:

*Floppy disks - Many newer laptops do not have floppy drives, so this could be limiting.

*CD or DVD -This may be the best choice as many laptops contain CD or DVD write drives and the quantity of data they can hold is greater than the previous methods.

*External Drives - these are also available in a different of sizes and capacities. Most external drives are plug and play, which makes setup and use to be easy.
