Windows 11 BitLocker Encryption Bypassed To Extract Volume Encryption Keys

Researchers demonstrated a physical-access technique to extract BitLocker Full Volume Encryption Keys (FVEKs) from RAM by abruptly restarting a running Windows 11 system, booting a custom UEFI environment from USB, dumping memory, and locating keys (e.g., under the dFVE kernel pool tag). The report describes methods to preserve RAM contents (cold cooling, maintaining power, shorting reset pins), potential Secure Boot bypass approaches, step-by-step attack actions, and mitigation recommendations such as enabling hardware security (TPM) and enforcing physical protections.
