If you're not able to boot from another OS because the firmware is locked down, booting from removable media is disabled, and a software crypto product is installed, this is a handy way to bypass all that. If you have non-administrator credentials that get you past the bootloader or the entire boot process hasn't been made secure, this is an extremely trivial exploit requiring no special tools. I'm making the assumption that the software (or hardware?) crypto is correctly tied to that machine's TPM to prevent removing the disk and booting it on another machine. Depending on the exact configuration of the target machine, this would enable the retrieval of sensitive data assumed to be secure, or else insertion of a trusted machine with malicious payload into a secure environment. I can think of quite a few environments I've encountered where all of the above assumptions stand. On 2013-06-29 14:49:16 (+0200), Alex wrote:
Or just add an account to SAM file with local admin privs (while booting from another OS). Nothing new or special imo.
