T security and data protection firm Sophos is warning that a new virus attacking the users of jailbroken iPhones is the most serious to date, since it makes infected iPhones into zombies, joining them to a botnet.
Two weeks ago the first ever iPhone virus appeared, changing infected victim's wallpaper to an image of 1980s pop star Rick Astley. However, aside from gobbling up bandwidth and Rickrolling iPhones it had no additional criminal intentions.

Sophos reports that over the weekend, a new iPhone worm (informally called "Duh" or "Ikee.B" by security researchers) was reported spreading in the wild in The Netherlands, designed to upload banking information to a server in Lithuania and to follow orders from remote hackers. The "Duh" worm hunts for vulnerable iPhones on a wider range of IP ranges than Ikee, which was only ever reported in Australia. "Duh" includes IP ranges in several countries, including The Netherlands, Portugal, Australia, Austria, and Hungary.
