bitlocker bypass

About this tag
The bitlocker bypass tag covers vulnerabilities and exploits that allow attackers to circumvent Windows BitLocker encryption, particularly through physical access and the Windows Recovery Environment (WinRE). Key topics include YellowKey (CVE-2026-45585), a publicly disclosed bypass using a prepared USB device in WinRE, and CVE-2026-45658, a physical bypass fixed in June 2026 Patch Tuesday. Discussions highlight the tension between recovery convenience and security, the role of TPM trust, and mitigation strategies for enterprise administrators. The tag also addresses related privilege escalation flaws like GreenPlasma and broader disclosure politics.
