  • Bitlocker is extra vulberable because it stores the key in the TPM and requires no password to boot. An attacker can extract the key even if the computer is off when they get it.

    This is not true.

    You would additionally need to bypass Secure Boot with a separate exploit such as the one in this article (which is mitigated by disabling USB boot) or LogoFAIL to put the TPM PCRs in a state where the keys can be released.

    LUKS2 is no different here as either can be TPM-only or require a separate PIN.
