Researchers at SRI International's Malware Threat Center have released a paper examining the iKee.B worm that recently infected jailbroken iPhones.

"The worm infected only those iPhones that had been jailbroken, and once on the devices, copied all of the phone's SMS messages and sent them off to a remote host," writes threatpost's Dennis Fisher. "Like PC-based botnets, iKee.B assigned each infected iPhone a unique identifier so that the command and control server could send specific new instructions to each individual device."

"The payload of iKee.B was fairly benign -- if potentially embarrassing -- as these things go, but clearly demonstrates the potential for greater damage from future attacks," Fisher writes.
