iPhones under attack from Rick Astley worm

Some iPhones have come under attack from a worm that replaces the devices' default wallpaper with a picture of Rick Astley - the pop star whose 'Never Gonna Give You Up' song is the subject of the Rickrolling prank craze.

The first reports of the worm, which affects jailbroken iPhones, appeared over the weekend in Australia.

Security companies have warned owners of jailbroken iPhones to change root log-in passwords immediately.
