- The YellowKey zero-day exploit allows complete access to BitLocker-encrypted drives by copying files to a USB stick and rebooting into recovery mode.
- The exploit’s files vanish from the USB after use, suggesting a concealed backdoor that raises serious security and political concerns.
- YellowKey affects Windows Server 2022 and 2025 but not Windows 10, and it can bypass TPM-and-PIN configurations.
- Another exploit, GreenPlasma, enables local privilege escalation to system-level access, posing significant risks especially to server systems.
could have made some insane cash selling this, but no amount of money will stand between me and my determination against Microsoft.— Chaotic Eclipse (Nightmare-Eclipse) – regarding the YellowKey zero-day exploit and their stance against Microsoft.
