Mobile phones are a boom in the 21st century and with their increasing use, threats from malware are on the rise. Nowadays, more and more people are using highly advanced smartphones. According to the latest reports from industry analysis more than 250 smart phones are going to be sold in the year 2011. The year 2010 has shown a drastic increase in malware on mobile devices, around 46% up from the year 2009. More phones means more targets for the troublemakers. Years of being overestimated by experts of security software, mobile malware is finally a real threat. Nowadays worms are spreading fast because smart phones are used for accessing Internet.

Around 15 variant of CommWarrior have been detected. The malware was first found in March 2005. CommWarrior exploits the Bluetooth user interface to influence victims to set-up malware on their phones. As soon as it gets active, it can extend quickly via Bluetooth connections, mails, multimedia messages and memory cards. It automatically replies to incoming messages and MMS messages.

These days some of the common mobile malware are like Cabir which drains down your cellphone battery as it copies itself with constant Bluetooth scanning, as soon as it is connected to your phone via Bluetooth. Doomboot is also a mobile malware which pretends it to be an edition of the Doom 2 video game and so it forces user to download and install it. If a user installs this malware, it would prevent the mobile from booting. This malware may also install Cabir and Commwarrior on a smart phone.

Overall these factors, with an increase in the smart phone usage, suggest that mobile malware is going to pose a big threat. Only time will tell what’s going to happen in future. People need to pay much attention on these types of threats before it is too late. Mobile users should install effective security software on their cell phones.
