First Worm written in C by ikee for iPhone.

This worm exploits the fact that most jailbroken iPhone/iPod touch users install SSH and also neglected to change the password for root / mobile (which is "alpine" by default). Once a device is infected, it disables the SSH service and then attempts to infect more devices.
