For some reason wifi vendors typically ship devices without any radio firmware at all, but leave it up to the driver to load it. Rendering the device 100% useless without loading some external proprietary blob.
Hard drives don't have that problem.
- andrewflnr 8y agoHard drives definitely have proprietary blobs on them. You just have even less visibility on them.
- hueving 8y agoA key difference is that a hard drive can't secretly send information out. I'm fine with an isolated component the rest of the architecture can treat as a black box (even sending only encrypted data to it). But the wifi chip can easily build its own IP packets and leak a bunch of information to the internet or it can have an easily exploitable backdoor.
- walrus01 8y agoa hard drive is a huge source of attack vector. In particular if you're running full disk encryption with a very tiny unencrypted ext2 boot/grub2 partition, malicious firmware on a disk can intercept the plaintext keystrokes for a passphrase-unlock on FDE. This is a known intelligence agency attack vector. https://theintercept.com/2015/04/27/encrypting-laptop-like-mean/ https://theintercept.com/2015/04/27/encrypting-laptop-like-m... see the "attacks against disk encryption" section.
- hueving 8y agoI wouldnt describe that as a huge source considering it requires a tpm vulnerability in secure-signed envs.
- walrus01 8y agoThis specific platform has all of the tpm module feature set disabled, no? Since the code running inside the tpm is proprietary and closed. To the best of my knowledge super gpl zealot users rarely choose to store a key in the tpm for full disk encryption unlocking purposes.
