Cell Phones and Viruses

By: Matjaz

If we compare PC field and cell phone field in case of viruses we would tell that now is not so easy to create a PC virus (but it is not impossible) but is really easy to create a cell phone virus! The reason is that it's usual to have an anti-virus program installed in our computer and it's unusual to have it installed in a cell phone. Another side of this thing is operation system similarity PC with cell phone. It means, that it's really easy just to adapt an existing PC virus to cell phone's operation system.

First mobile's phone virus was found out three years ago. It was just a touch of virus to try to spread from a cell phone to another cell phone. Shortly, there came some another versions of it. They could do a lot of unwanted operations from starting to delete to ending to steal information. Nowadays there exist almost 400 types of cell phone's viruses.

What do we know about them? They need net - wire or wireless. Our cell phones can catch them by MMS and also internet connection by 3G, IC, Bluetooth, WiFi and wire connection with PC. They can look like pictures, MP3s (rings), videos or useful applications. Of course, to activate a virus user has to consent it, but now users are not thinking about cell phone's viruses and they consent it in moment with maximal trust. After the consent, the cell phone's virus can do everything it wants. As an example, they can send MMS to all your contacts in your cell phone. How many contacts do you have in your cell phone? Average is 200. How many times do you think your virus will do it? And that's not all, a virus can delete or change information or applications in your phone and even fully destroy it.

Most from cell phone's viruses are working in cell phones with operation system like Symbian or Windows mobile. There aren't many cell phones with those operation systems, but in short future there won't exist a cell phone without operation system on this base.

And the result? Unwanted monitoring, data stealing (credit card's PIN codes)! In this case you are the first one who makes a decision to open unknown files and applications. Also deactivate WiFi and Bluetooth in time you don't need it. At the end don't forget to update your operation system and anti-virus system for your cell phone.
