There is actually an interesting point regarding TPM+PIN and systemd-cryptenroll: The data sealed in the TPM can directly be used to decrypt the disk (it is base64 encoded and used as a passphrase for a luks key slot). The PIN is only used to authenticate the TPM's unsealing of the data.
In contrast, the unsealed BitLocker data still needs to be decrypted with the pin to get to the VMK.
When our attack is successfully executed on a target, this means that TPM+PIN is broken on systemd-cryptenroll, and as secure as PIN-only with the same PIN on BitLocker.
