We demonstrate how to permanently reflash Intel BIOSes on the latest Intel Q45-based systems. In contrast to a previous work done by other researches a few months earlier, who targeted totally unprotected low-end BIOSes, we focus on how to permanently reflash one of the most secure BIOSes out there, that normally only allow a vendor's digitally signed firmware to be flashed. As an extra bonus we describe yet-another-one, on-the-fly, previously undisclosed attack against SMM on Intel platforms affecting most of the recent chipsets.
