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

Smells like a compromise. Microsoft enables BitLocker by default, thus protecting companies and users at scale. But the price is a backdoor they hope noone finds.

Someone else claimed this doesn't affect people who actually care about security and enable boot-time password protection.

No. RedSun and Bluehammer were LPEs

No, that's not what the bypass does. Maybe go try it out and verify it before you come to your quickly made conclusions?

It's not tied to "automatically decrypted" volumes, whatever that would imply for your setup requiring a pretty pointless TPM keystore for that.

If your case were true, it would also imply that any bitlocker cryptography never really worked because it was automatically decryptable without the need for a password/hash/whatever to get your keys from the keystore, which actually makes it so much worse. Even worse than the previously known coldboot attacks.

  • its pretty obvious you have no idea how bitlocker works, and its various modes - TPM only, TPM+PIN, PIN only

      How could anybody besides a Microsoft employee, given the appearance of this bypass technique?
