iPhone worm Rickrolls jailbroken phones

Security researchers warn iPhone users of the ikee worm, which uses SSH default passwords to hack the smartphone and change the wallpaper to a Rick Astlee photo.

A hacker from Wollongong, New South Wales is claiming responsibility for the new ikee worm, which started to infect jailbroken iPhones in Australia and is a possible threat for iPhone users in other countries. The worm, which the SANS Institute Storm Center calls very simple, scans certain IP addresses and uses Cydia – a replacement packaging and repository manger for jailbroken iPhones – to try to login to the IP address as root.

It’s easy to determine if your jailbroken phone has been infected. The end result is a wallpaper image of 80s pop singer, Rick Astley. The worm’s author, who goes by the name Ash/ikex, said he was bored and wanted to shed light on iPhone users running SSH without changing the default password.
