An x86 bare metal RAM dumper

Adafruit Blog is reporting on BareMetal RAM Dumper, an x86 bare-metal tool that boots from USB to dump a system's RAM to disk.

This technique could allow extraction of sensitive information like encryption keys, which the tool accesses via BIOS interrupts and protected mode.
