Ohh this one is SPICY.
To say that this is dangerous is an understatement. Not only is it an immediate concern as BitLocker cannot be trusted for encrypting drives, but the way the exploit executes and its files disappear also raises very uncomfortable corporate and/or political questions. YellowKey also reportedly works in Windows Server 2022 and 2025, but not in Windows 10.

>There's nothing more dangerous than a bored engineer with a screwdriver, and hell hath no fury like a security researcher scorned. Last month, Security researcher Chaotic Eclipse (aka Nightmare-Eclipse) published two zero-day exploits, BlueHammer and RedSun, that made Windows Defender offer up system administrator privileges. They did this after their disclosure reports were allegedly dismissed by Microsoft's security team, resulting in a vendetta of sorts. Eclipse has now done it again, posting two new zero-day exploits, the first one an extremely serious BitLocker exploit named Yellow Key that grants full access to a locked drive. The second one, GreenPlasma, doesn't have a complete proof-of-concept (PoC), but it allegedly performs a local privilege escalation and gains system-level access. Given Eclipse's track record, it's a fair bet that it works as advertised.
