The Bitlocker encryption used by Microsoft for Windows for data storage devices can be bypassed by software via the Bitpixie vulnerability (CVE-2023-21563) if certain boundary conditions apply. A security researcher has shown how the master key can be read from the RAM and used for decryption within minutes without a hardware hack if pre-boot authentication is missing under Windows.

[German]The ReFS file system introduced by Microsoft in Windows a long time ago seems to be a "stepchild" of the developers.
