specifically to infect iPods. They named the virus "Podloso".In order for the virus to function, Linux has to be installed on the iPod. If the virus is installed on the iPod by the user, the virus then installs itself to the folder which contains program demo versions. Podloso cannot be launched automatically without user involvement.
Once launched, the virus scans the device's hard disk and infects all executable .elf format files. Any attempt to launch these files will cause the virus to display a message on the screen which says "You are infected with Oslo the first iPodLinux Virus".
However it is a typical proof of concept virus, which is created in order to demonstrate that it is possible to infect a specific platform which does not pose a real threat.
Last year in September, Apple shipped some Video iPods which were carrying a malicious file, Windows RavMonE.exe. Windows RavMonE.exe affected only Windows computers and up to date anti-virus software could detect and remove it.
