A high-profile hack of the Apple Macbook could be used to bring down Windows computers.

The Apple hack that helped security researcher Dino Dai Zovi claim a $10,000 prize at last week’s CanSecWest security conference, is based on the way Apple’s QuickTime Media Player works with the Java programming language.

Since QuickTime works on both Windows and the Mac, both operating systems are vulnerable.

Initially it was thought that Dai Zovi’s bug was thought to lie in Apple’s Safari browser, a standard component of Mac OS X. But security companies say that it is clear that users of Firefox, which supports QuickTime on both Windows and the Mac, are also at risk.
