Cold Boot Tools Released

/, Security Tools/Cold Boot Tools Released

The Princeton/Wind River/EFF team just released their memory research tools at The Last HOPE conference.

The bios_memimage tool is written in C and uses PXE to boot the machine and copy the memory. The package also has a disk boot dumper with instructions for how to run it on an iPod. There’s also efi_memimage which implements the BSD TCP/IP stack in EFI, but it can be problematic. aeskeyfind can recover 128 and 256bit AES keys from the memory dumps and rsakeyfind does the same for RSA. They’ve also provided aesfix to correct up to 15% of a key. In testing, they only ever saw 0.1% error in there memory dumps and 0.01% if they cooled the chips first.
