iPhone users that have jailbroken their iPhones have come under attack from a new worm. The worm seems to not have malicious intentions, and simply changes the background of the phone to a picture of Rick Astley. The affected phones all have something in common other than being jailbroken, default passwords. Neglecting to change the default password provides one of the easiest targets for hackers. The worm spreads between phones that have an SSH port open, and is able to spread itself from phone to phone. It appears that it is only a matter of time before someone decides to take advantage of this for personal gain instead of laughs.
