Note that RedSun and Bluehammer were silently patched, with no response to the CVEs by Microsoft, and not accrediting the researcher's work.
That's what this is about. Microsoft doing bad security practices while trying to get away with it, leading to this outcome.
The researcher also claims to have another version ready which allows to also bypass TPM+PIN via a similar backdoor, which I'm inclined to believe.
Why do I believe that? 5 ring 0 zero days within 3 months are so statistically unlikely to be found, by the same person, in such a short time. Whoever this person is really knows their exploits, and must be in the league of Juan Sacco.
the only way to bypass PIN would be an actual backdoor in Bitlocker. no way around that. an actual backdoor in microsoft encryption was never documented, and there are Snowden documents showing FBI pressing Microsoft into introducing one and Microsoft refusing
so I call bullshit on the PIN bypass
You're assuming the PIN was ever connected to the key itself in the first place. We don't know how that mechanism works, it could just be a totally separate gate that IS bypassable.

A USB stick containing a masterkey to decrypt a bitlocker volume is literally the definition of a backdoor.
Go on, try it out. It works.
no, to access a bitlocker volume which automatically decrypts
thats an LPE, not an encryption backdoor
the USB stick doesnt decrypt bitlocker, it just gives you root after bitlocker was AUTOMATICALLY decrypted
