A Trojan horse, called MP3Concept or MP3Virus.gen, has been discovered that masquerades as an MP3 file.

And is if that wasn't interesting enough...

The Trojan appears to be an ordinary MP3 file. In fact, it will play music if launched from inside a digital jukebox like Apple's iTunes. The song plays and the Trojan isn't activated.
