alt Hacker NewsHow is this even possible, backdoor or no? Isn't the whole point of this type of encryption that even a compromised machine can't decrypt without the passphrase? If this works it means that the key is stored unencrypted somewhere?

Presumably the key is stored in the TPM
Most setups only have the key stored in the TPM, so all you need to get it back is a signed/trusted bootloader.
Ideally you'd want that key to be further protected with a password or some other mechanism because it's not impossible to extract TPM keys.
