The first known actual iPhone worm has been spreading across jailbroken iPhone and this virus is spreading from Australia. However it is believed that all the jail broken iPhone sets are under serious threat. This virus break into iPhones and change your lock screen wallpaper to an image of the 1980s popstar Rick Astley  with a message   “ikee is never going to give you up “
it is further noticed that this virus can only infect users which are using jail broken iPhone.  Sophos  the IT security  and data protection company have yet not confirmed   any outbreak of this virus outside the Australia.

and to be clear, this worm can’t get to
stock iPhones or jailbreak owners who haven’t installed SSH – but if
you’re running a hacked phone we’d say you should change that root
password just to be safe right away.
So if you have installed SSH, here’s how, to change the password

Type: ssh root@(iPhone IP address)

When prompted for the password type: alpine

Now you’re connected the phone…

type: passwd

It should then prompt your for a new password – type one that you’ll remember.  Do not forget it as there is no easy way to reset.
