Jailbroken iPhones have been attacked again. iBotnet.A is the latest in a string of attacks to exploit the root password common to iPhones running SSH. The only way to insure security (besides NOT jailbreaking your iPhone) is to change your root password.
iBotnet.A (also known as Ikee.B or the "Duh" virus) spreads from iPhone to iPhone across the network sending personal data to a server located in Lithuania. Address ranges from service providers in Portugal, Hungary, Australia and the Netherlands have been targeted.
