First Symbian OS virus to replicate over MMS

Shachaf writes "A new virus, CommWarrior.a, is the first to replicate over MMS (Multimedia Message Service). From the article: 'Multimedia Message Service (MMS) is a more advanced version of the Short Message Service (SMS) familiar to users of GSM based handsets around the world, and allows rich content such as pictures, sounds, video, and applications to be sent as well as text.', and '"With MMS messages typically costing between $0.25 and $1.00 CommWarrior could prove expensive to anyone unlucky enough to be infected by it. As the virus runs silently in the background it could be quite some time before the user becomes aware of the potentially hundreds of MMS messages that have been sent," said Aaron Davidson, CEO of SimWorks.'"

It is just that this feature is turned off by default (at least on the phones that I have seen).
