But even that is very light on details: The attack exploits the fact that the firmware settings governing the behavior of the boot process are not protected against manipulation by a physical attacker. Using a simple hardware tool, an attacker can rewrite the non-volatile memory chip that contains these settings, disable memory overwriting, and enable booting from external devices. The cold boot attack can then be carried out by booting a special program off a USB stick I suppose they attach something JTAG?
