Vulnerabilities in BMCs and AMD Microcode

This chapter explores the security vulnerabilities tied to Baseboard Management Controllers (BMCs) and AMD CPU microcode, emphasizing the risks of firmware backdoors and microcode integrity. It discusses the challenges users face in verifying microcode updates and introduces open-source initiatives aimed at improving this process. The conversation highlights the broader implications of securely managing firmware in the context of evolving technologies like blockchain and the potential for unauthorized access through neglected infrastructure.
