The Cabir Virus

This was the first cell phone virus and it appeared in June of 2k4. A network worm dubbed Cabir, it was a proof of concept. It spawned several later variants and spread between mobile phones by using a Symbian operating system distribution file that was modified to masquerade as security software. Users who ran the file saw the word “Caribe” on their screens and the worm set itself to run whenever the phone was on. Once a phone was infected it scanned for other Bluetooth phones to spread to.
