History
iPhone owners of Australia reported that smart phones had been infected by a worm that changed their iPhone wallpaper to Rick Astley, a 1980s pop singer.{{cite web|url= https://www.zdnet.com/article/source-code-for-ikee-iphone-worm-in-the-wild/|title= Ikee worm targeting customers of Australian mobile carriers|website= ZDNet|access-date=2009-11-10}} It affected smartphones if the owner did not change their default password after installation of SSH. Once the Ikee worm infected, it would find other iPhones on the mobile network which were vulnerable and infect them as well. The worm wouldn't affect users who hadn't jailbroken or installed SSH on their iPhone.{{cite web|url= https://nakedsecurity.sophos.com/2009/11/08/iphone-worm-discovered-wallpaper-rick-astley-photo/|title= First iPhone worm discovered – ikee |date= 8 November 2009 |accessdate=2009-11-08}} The worm does nothing more than changing the infected user's lock screen wallpaper.{{cite web|url= http://www.computerweekly.com/news/1280091290/First-ever-iPhone-worm-Ikee-unleashed-by-Aussie-hacker|title= First ever iPhone worm Ikee unleashed by Aussie hacker|accessdate=2009-11-09}} The source code of the ikee worm says it was written by Ikex.{{cite web|url= https://www.sophos.com/en-us/press-office/press-releases/2009/11/iphone-worm-job.aspx|title= Ikee worm author wins job at iPhone app firm|accessdate=2009-11-26}}
