![]() In developer mode, an attacker can extract the encryption key stored in the TPM enclave. With this vulnerability, hackers can access developer mode. Known flaws have been addressed, but let’s note that hackers regularly-and successfully-attack BitLocker.Ī few weeks ago, the New Secret-Spilling Hole in Intel CPUs Sends Company Patching (Again) article by Dan Goodin on Ars Technica, said researchers found a way to obtain the fuse encryption key unique to each CPU. Over the years, cold boot attacks, ability to bypass authentication, ability to bypass BitLocker encryption, and so on are all part of the BitLocker legacy. ![]() Unfortunately, BitLocker and security concerns go hand-in-hand. An unsuccessful validation will prohibit access to a protected system. When used in conjunction with a compatible Trusted Platform Module (TPM) on the host computer, BitLocker validates the integrity of boot and system files before decrypting a protected volume. A volume, or logical drive, is a single storage area that has a single file system.īy default, BitLocker uses the AES encryption algorithm in cipher block chaining (CBC) or XTS mode with a 128-bit or 256-bit key (CBC is is applied to each individual disk sector). BitLocker is designed to protect data by encrypting entire storage volumes. Microsoft Windows includes a software encryption feature called BitLocker.
