If your iPhone has been jailbroken, change your passwords now, advised Paul Ducklin, Sophos Australia's chief of technology. Ducklin said the writers of this virus included a program call "Duh", which added malicious capabilities not present in last month's ikee release.
The new password installed by this virus was "ohshit", which can be used to remove the threat of further remote attacks on an infected device. Ducklin said to clean up the device by searching the file "directory/private/var/mobile/home", type in "passwd" to initiate the command, and change the password. "Otherwise the buggers can get back in anytime they want," said Ducklin.
