There is a new dangerous virus/worm on Symbian OS based cellphones.
The virus can spread using MMS. Is Linux based cellphones more secure?
From Cnet:
The malicious software, dubbed "CommWarrior" and described as a virus by some antivirus companies, takes aim at the version of the Symbian operating system running on Nokia Series 60 handsets. F-Secure, SimWorks International and other security providers issued reports about the threat Monday.
CommWarrior attempts to spread by sending messages via Bluetooth wireless connections and Multimedia Message Service--different from the Cabir virus, which only used Bluetooth to proliferate.
MMS, a mobile technology for sending text messages that can also include images, audio or video, is built into devices from Ericsson, Motorola and others. CommWarrior, however, only affects Nokia Series 60 phones.
As MMS can be used to send text messages worldwide, it has a greater reach than the short-range Bluetooth and so could be forwarded more rapidly, researchers said.
"At its best replication speed, Cabir can only spread as quickly as planes fly," said Mikko Hypponen, antivirus research director at Finland-based F-Secure. "But MMS viruses are more comparable to e-mail worms like Bagle, MyDoom, Sobig and others. An MMS threat can travel around the world in hours, so in that regard, it's much more dangerous."
A representative for United Kingdom-based Symbian said the company is aware of the problem and researching the threat with Nokia and its security partners.
