How to secure your jailbroken iPhone SSH password against worm

Remember the First iPhone worm hits Jailbroken iPhones? The previous worm changed your wallpaper to an image of 1980s pop crooner Rick Astley. Now what? A new report says that a new variant of the original “Ikee” iPhone worm, called 'Ikee-B' like the first Ikee makes use of an SSH backdoor on jailbroken iPhones. This one targets jailbroken iPhones with unsecured SSH passwords. It is designed to steal passwords and financial details of people who log onto the website of the Dutch bank ING using an infected iPhone. So far all the infections reported are restricted to The Netherlands, but Ikee-B could potentially affect an IP range that includes several other European countries as well as Australia.
