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.
This is bad, bad news. I’ve found that the level of knowledge of mobile phone viruses is incredibly low, even among techinically-knowledgable users. Ease of spreading, plus low levels of knowledge, equal a bad outbreak.
