First iPhone Worm Discovered: Rickrolls Jailbroken iPhonesS

Jailbreakers in Australia are being infected by a worm that changes their wallpaper to an image of Rick Astley. And while that sounds kinda funny, it's another reminder to make sure you've changed the default password on your jailbroken iPhone.

Sophos reports that the worm appears to do nothing worse than spread and change the unlock screen wallpaper. It could have spread to other countries, but is most likely confined to Australia at this point.

The worm's creator, a 21 year old student from Sydney, told Australia's national broadcaster: "The virus itself is not malicious and is not out to hurt people. It's just poking fun and hoping waking people up a little."

But with rickrolling going on, and that Dutch guy holding hacked jailbroken phones to ransom, it may only be a matter of time until some dip-shit does something more malicious.

So if you're a Jailbreaker, go into Cydia, install the MobileTerminal app, and use the passwd command to change the default from "alpine", to something a little more secure. [Sophos]
