Preventing Initramfs Attacks in TPM-Based Disk Encryption

This is a 2-part series where we'll explore vulnerabilities in systems that use Trusted Platform Modules (TPMs) for disk encryption, exposing the risks of unverified initramfs images and bus sniffing attacks.

In this article, we'll look at how disk encryption uses the initramfs and you'll see why using PCR 9 is so important for properly securing a system.
