(Estimates suggest that 6-8% of iPhones are jailbroken.) Jailbroken iPhones at risk are those where ssh is installed, and where the default password has not been changed.

This worm starts by searching its local network, as well as a number of IP address ranges, for available devices to infect. The address ranges it scans include those of ISPs in the Netherlands, Portugal, Hungary, Australia, and if an appropriately unprotected iPhone is found, the worm can copy itself to these devices.

When active on an iPhone, the iBotnet worm changes the root password for the device (from
