There is a new iPhone worm that uses the insecure SSH service installed on jailbroken iPhones.  Last week, there was discussion about an attack on iPhone users in the Netherlands where the attackers demanded owners pay 5 EUR to get rid of the Trojan.

"Jailbroken" (or hacked) iPhones or iPod Touch devices are devices where users have bypassed Apple's official distribution and are running unofficial code.  Once an iPhone or iPod Touch is jailbroken, users are able to download various applications previously unavailable through Apple's App Store from unofficial installers such as Cydia or Rock App.
