Microsoft BitLocker – YellowKey 제로데이 익스플로잇

The YellowKey zero-day exploit reveals a critical vulnerability in BitLocker encryption, allowing physical access to bypass drive protection without credentials on Windows 11 and Server 2022/2025. This discovery fundamentally undermines trust in one of Microsoft's most widely-used security features, affecting millions of devices where BitLocker is the default protection mechanism. The public disclosure of this and concurrent vulnerabilities (GreenPlasma, BlueHammer, RedSun) highlights Microsoft's apparent insufficiency in responding to reported security issues.
