First malicious iPhone worm slithers into wild
Found on The Register on Saturday, 21 November 2009
In addition to connecting to a Lithuanian master command channel, it also changes the root password for the device, making it harder for owners trying to regain control. Infected iPhones are also tagged with a unique ID number.
One would think people who are smart and energetic enough to jailbreak a smartphone would know about the perils of SSH and default root passwords, but the success of these worms suggests otherwise.
If you manage to jailbreak your phone, at least fix the default password. There is nobody else to blame but the owner of the phone who failed at the most basic security guidelines.
