Re: [Full-disclosure] Firewire Attack on Windows Vista

...Windows would not do this. It would only open up access to devices
that it thought needed DMA. This is why Metlstorm had to make his Linux
machine behave like an iPod to fool Windows into spreading it's legs.

So the iPod software opens up the whole address space? I don't get it.

No, the iPod device signature makes Windows drivers think it should
allow DMA access for that device because it detect it as a disk device.
Other disk device signatures would likely work the same way, that's just
the one he happened to emulate.
