Very end of the article explains you need access to the TPM communication hardware, which no longer occurs external to Intel and And cpus

To *newer Intel and AMD cpus and only certain models.

There's a lot of current hardware that uses embedded TPMs. It also depends on the communication path between the CPU and the module, but chances are it will be clear text and in some, via LPC.

Should be noted that if a password is asked to decrypt the drive it also doesn't work.

So offline (external) bitlocker drives that are unlocked with the key only.

Or internal bitlocker drives that are unlocked with AMD fTPM are excluded from this exploit?
