Throughout recent years, we have seen a resurgence in attacks targeting the lower levels of the technological stack. Looking to exploit the UEFI/BIOS environment, attackers have started exploiting a growing number of vulnerabilities below the Operating System (OS). This kind of attack aims at leveraging the complexity of gathering information about a device's lower-level configuration, which, combined with the lack of scalable management solutions at this level, makes detecting and remediating such attacks much harder. In this thesis, we will start by recounting a brief history of low-level attacks and then explain why platform security must focus on two fundamental challenges: digital transparency, i.e.
