The first known worm to target iPhones has struck. This relatively harmless worm only targets phones which have been jailbroken, suggesting perhaps that non-jailbroken phones may be tougher to target, and all it does is change the user’s home screen to a 1980′s era photo of Rick Astley with a line of text above his head reading “ikee is never gonna give you up”. As reported by Forbes, the worm is no way harmful, other than making you look at Rick Astley. The article states that the worm is hardly a threat and, “Instead, it seems to be half warning, half prank. Ikee’s author, who identifies himself or herself as ‘ikex’ in the worm’s source code, also wrote in the code that ‘People are stupid, and this is to prove it so,’ adding that users should read their phones’ manuals.” Although this one may not be malicious, it opens the proverbial “can of worms” and variants of this or new code altogether are now more feasible.

Edit (11/11/09): I’m seeing a lot of searches coming to this site looking for the source code of the virus. You should be ashamed of yourself and you will not find that or any other malicious code here.
