BitLocker BROKEN: A USB Stick Now Unlocks Windows Encryption
BITLOCKER BROKEN — A USB STICK NOW UNLOCKS WINDOWS ENCRYPTION
A security researcher dropped a zero-day called YellowKey that opens BitLocker-protected drives with nothing but a USB stick and a folder of files anyone can download. No password. No recovery key. No brute force. And the researcher says it's not a bug — it's a backdoor.
In this episode:
How YellowKey turns a $5 USB stick into a master key for Windows 11, Server 2022, and Server 2025
The FsTx folder, the WinRE component, and why Windows 10 is completely unaffected
Will Dormann's independent reproduction within hours of disclosure
Why TPM+PIN does NOT save you — and the only known workaround
The EFI-partition variant: 10 minutes alone with the device and it's over
What this means for HIPAA, PCI, SOC 2, and ISO 27001 compliance
