Delve into the potential vulnerabilities in lower layers of the software and firmware stack, focusing on the impact of persistent implants in system firmware, particularly UEFI. Witness the development and injection of a "hello-world" system firmware malware, and learn how TPM, a secure cryptoprocessor, can protect against such threats. Discover the role of TPM in granting access to system secrets only when the integrity of all stack layers is verified, enhancing overall platform security.
