Physical bypass of BitLocker drive protections
Published Apr 9, 2024 · Updated May 3, 2025
BitLocker security feature bypass in Microsoft Windows allows physically proximate attackers to defeat protected-drive safeguards. Microsoft has not published the affected BitLocker component or the operation that mishandles attacker-controlled input. Exploitation requires physical access, high privileges, and user interaction, and can expose, alter, or disrupt protected data.
