I say *possible* because *to me* it does not seem it would be immediately useful to cyber criminals, though they might be able to build on it, taking the exploit further. To perform the exploit as published you copy the FsTx folder to the System Volume Information on a USB stick, cause the system to reboot into the Recovery Environment, then hold down the Control key until it reboots. When it restarts you'll be at the Command Prompt with full access to the encrypted drive.
Of course, if you are in the running copy of Windows, which is necessary to pull this off, you already have access to the files on the BitLocker encrypted system disk, so while I may be missing something here, what is the point?
