Bypassing BitLocker Encryption on Windows 11 via Memory Dump

2024-12-30

This article demonstrates bypassing BitLocker encryption on Windows 11 by extracting the Full Volume Encryption Key (FVEK) from memory. By physically accessing the device and abruptly restarting it, an attacker can capture RAM contents, which may contain the FVEK. The author utilizes a UEFI application, Memory-Dump-UEFI, to achieve this. The process involves creating a bootable USB, forcefully restarting the system, booting from the USB, analyzing the memory dump, and using pool tags to locate the FVEK. The article details these steps and emphasizes the use of tools like dislocker to unlock the BitLocker-protected partition. The method is not foolproof and relies on several factors such as speed of memory dump and the timing of the restart.
