ikee worm & how to change your root ssh password for your Jailbroke iPhone

Though the ikee worm and other recent incidents have highlighted security risks facing users of jailbroken iPhones, the question remains: If you are using a jailbroken iPhone, just how insecure is it and what can you do about it?

The first known worm for the Apple iPhone is sweeping across Australia, and it is taking advantage of default SSH passwords on jail-broken phones.

What’s clear is that if you have jailbroken your iPhone or iPod Touch, and installed SSH, then you must always change your root user password to something different than the default, “alpine”. In fact, it would be a good idea if you didn’t use a dictionary word at all.

Presently it appears that the worm does nothing more malicious than spread and change the infected user’s lock screen wallpaper. However, that doesn’t mean that attacks like this can be considered harmless.

It looks like the only fix, since the worm disables ssh on the phone, is to reformat the phone. The files aren’t too terribly hidden, but how do you remove them if you can’t get into your phone? Reformat looks like the only way how.

If you would like to hear all about the worm from the creator itself you can get it from the Risky Business Podcast #131 from Apple’s itunes. or http://risky.biz/RB131

This looks like the start of things to come for mobile devices, Intego claims iPhone/Privacy.A a new worm is far more dangerous than the Ikee worm, takes advantage of the same vulnerability in the iPhone as the Ikee worm, allowing hackers to connect to any jailbroken iPhone whose owners have not changed the root password.

The tool reportedly allows a hacker to silently copy user data from a compromised iPhone including email, contacts, SMSs, calendars, photos, music files, videos, as well as any data recorded by any iPhone application insists Intego. This new hacker also tool gives no indication that it has invaded an iPhone.
