In recent years, we witnessed the rise of firmware-related vulnerabilities, likely a direct result of increasing adoption of exploit mitigations in major/widespread operating systems - including for mobile phones. Pairing that with the recent (and not so recent) leaks of government offensive capabilities abusing supply chains and using physical possession to persist on compromised systems, it is clear that firmware is the new black in security. This research looks into BIOS/UEFI platform firmware, trying to help making sense of the threat. We present a threat model, discuss new mitigations that could have prevented the issues and offer a categorization of bug classes that hopefully will help focusing investments in protecting systems (and finding new vulnerabilities). Our data set comprises of 90+ security vulnerabilities handled by Intel Product Security Incident Response Team (PSIRT) in the past 3 years and the analysis was manually performed, using white-box and counting with feedback from various BIOS developers within the company (and security researchers externally that reported some of the issues - most of the issues were found by internal teams, but PSIRT is involved since they were found to also affect released products).
