Physical authentication bypass through undisclosed mechanism
Published Aug 9, 2022 · Updated Feb 13, 2025
Security feature bypass in Windows Hello on affected Windows 10 and Windows 11 builds allows physically proximate attackers to bypass authentication. Microsoft has not published the flawed Windows Hello operation or how attacker-controlled input defeats its authentication decision. Exploitation requires physical access and can compromise protected data and actions without interrupting service.
