Bitlocker is among the most simply accessible encryption options accessible at present, being a built-in characteristic of Home windows 10 Professional and Home windows 11 Professional that is designed to safe your knowledge from prying eyes. Nonetheless, YouTuber stacksmashing demonstrated a colossal safety flaw with Bitlocker that allowed him to bypass Home windows Bitlocker in lower than a minute with an inexpensive sub-$10 Raspberry Pi Pico, thus getting access to the encryption keys that may unlock protected knowledge. His exploit solely took 43 seconds to steal the grasp key.

To do that, the YouTuber took benefit of a design flaw discovered in lots of methods that characteristic a devoted Trusted Platform Module, or TPM. For some configurations, Bitlocker depends on an exterior TPM to retailer crucial info, such because the Platform Configuration Registers and Quantity Grasp Key (some CPUs have this built-in). For exterior TPMs, the TPM key communications throughout an LPC bus with the CPU to ship it the encryption keys required for decrypting the information on the drive.
