The viral 'Rickrolling' campaign, that inadvertently tricked people into playing Rick Astley's 1987 hit "Never Going to Give you Up" has recently hit Australian iPhones, leaving users in a panic as so far, there is no antidote. Researchers are saying this attack is the world's first iPhone worm, which targets jail broken iPhones (which for the layman are phones that have been unlocked from the service provider).
For the layman as well, when a user jailbreaks an iPhone they are able to access the thousands of applications that didn't conform to the apple guidelines (i.e porn), however it makes the iPhone vulnerable as the terms of the warranty are automatically void.
The worm, aware of this fact, operates by showing a picture of Rick Astley, with the wall paper displaying the message "ikee is never going to give you up". Users who tried to delete the image, found they were unsuccessful when they rebooted their phone.
The hacker 'ikee' who has claimed responsibility for the worm, said that he wanted to bring awareness to the danger of failing to change the iPhones root password, which is a step that is so often forgotten by users. So far the worm is only in Australia, however now that the idea has surfaced I feel there will be a lot of copycat hackers. So, if you do jailbreak your iPhone make sure to change the root password to avoid these nasty complications.
