Security software vendor Kaspersky Labs claims to have discovered the first virus designed to infect iPods. Kaspersky has named it Podloso. It's a proof of concept program and "does not pose a real threat," according to Kaspersky.
The virus is a file which can be launched and run on an iPod. For the virus to function, Linux has to be installed on the iPod, and the user has to install the virus themselves. The virus settles itself into the folder which contains program demo versions.
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”, said Kaspersky.
