UEFI - Summary of Attacks against BIOS and Secure Boot
A variety of attacks targeting platform firmware have been discussed publicly, drawing attention to the pre-boot and firmware components of the platform such as BIOS and SMM, UEFI secure boot and Full Disk Encryption solutions. This talk will detail and organize some of the attacks and how they work. We will cover attacks against BIOS write protection, attacks leveraging hardware configuration against SMM memory protections, attacks using vulnerabilities in SMI handlers, attacks against BIOS update implementations, attacks bypassing secure boot, and various other issues. We will describe underlying vulnerabilities and how to assess systems for these issues. After watching, you should understand how these attacks work, how they are mitigated, and how to verify if your system has any of these problems.
