"The Cabir worms spread between smart phones using a specially formatted Symbian Installation System (SIS) file disguised as a security management utility. Infected phones scan for vulnerable handsets using the short-range Bluetooth wireless connection, then send a file containing the worm to those phones. To be infected by Cabir, mobile phones must be running Symbian OS with the Series 60 software and have the Bluetooth wireless feature in "discoverable" mode, making them open to new connections, according to Hyppönen. In addition, the owner of the phone would have to press a key to dismiss a security warning about installing software of unknown origin, and then another to agree to install the file being transmitted, F-Secure said.
Users know when their phones are infected because phone batteries are rapidly consumed, he said.
At the end of last year, total shipments of Symbian-based smart phones reached 25 million, with eight handset manufacturers including
Nokia,
Siemens, and
Sony Ericsson Mobile Communication, supplying 41 phones.
Nokia, the world's largest handset manufacturer, owns slightly under 50 percent of Symbian."
