Second iPhone worm behaves like botnet

Mikko Hyponen, chief research officer at F-Secure, said in a blog post that the new worm, like the first, affects jailbroken iPhones with SSH (secure shell) protocol enabled and unchanged default passwords. The Finnish security company has yet to give a name to the new threat.

Ikee, another threat that was discovered earlier this month, is said to infect vulnerable phones in Australia. When Ikee strikes, it alters the iPhone's wallpaper to an image of Rick Astley with the message "ikee is never going to give you up".

"The worm is not widespread, but it is much more serious than the first iPhone worm as it seems to try to steal information from the devices," Hyponen said about the new worm in the blog post.
