We've found a mobile phone virus that appears to be the first one that replicates via MMS messages.

MMS stands for Multimedia Messaging Service. These are text messages that include an image, audio or video. MMS messages are sent from one phone to another or to email.

Phone viruses so far have been spreading over Bluetooth - so they only affected phones that were nearby. A MMS virus can potentially go global in minutes, just like email worms do.

We're currently analysing CommWarrior, which runs on Symbian Series 60 platform. It attempts to spread over both MMS and Bluetooth. The virus seems to be from Russian, as it contains text that says "OTMOP03KAM HET!". Which roughly translates to "No to braindeads".
