Adam Boileau a security reacher from New Zealand released source code for his Winlockpwn scripts. He first demoed the hacking physical-memory-DMA feature of Firewire at Ruxcon 2006 . Yes, thats right this is a feature of firewire that basically destroys the security feeling of any computer screensaver/lockscreen (Windows/Mac/ Linux) with a firewire port. This is more of a complex hack then say pressing the “escape” button in windows 98 but it gets the job done just as quick.
as adam puts it:
Yes, this means you can completely own any box who’s firewire port you can plug into in seconds.
