Alright. You now have jailbroken your iPhone and everything seems fine. Then all the sudden some hero decided to write a worm which infects jailbroken iPhones. BUMMER! What can you do? For those who don’t know, iPhone runs on a modified Mac OS core. This is loosely based on a UNIX-like environment. Once you have installed OpenSSH on your phone, you would open a SSH connection to your iPhone with a default root password of “alpine”. This is what those worm writers are riding on to get into your iPhone.

What do you need to do?

4. Once you are in the Terminal screen, type “passwd” and press Enter. You will be asked to key in your existing password (by default, it will be “alpine”). Then you will be required to key in a new password twice. Choose any secure password you like. Once you have successfully changed the password, you will be safe (for now).
