The only possibility left for the attacker in this case is to boot normally to unlock the encryption key and then to bypass the Windows authentication to gain access to the data, which Haken's attack allows. The various stages of the boot process are cryptographically verified, so an attacker with physical access to a BitLocker-enabled laptop will not be able to boot from an alternative OS to read the data stored on its drive. The key is unsealed from the TPM only if the same boot process is followed as when BitLocker was first activated. Microsoft's full-disk encryption technology, which is available in the professional and enterprise editions of Windows, is specifically designed to protect data in case a computer is stolen or lost - in other words when an unauthorized individual has physical access to it.īitLocker stores the data encryption key in a Trusted Platform Module (TPM), a secure hardware component that performs cryptographic operations. That all changed when BitLocker was introduced in Windows Vista.
However, physical access did not used to be part of the Windows threat model, because in such a situation an attacker could boot from an alternative source, like a live Linux CD to access to the data anyway. This is a logic flaw that has been in the authentication protocol since Windows 2000, the researcher said.

However, the attacker could disconnect the laptop from the network in order to force a fallback to local authentication, which will now succeed because only the user password is verified against the cache. Logging in while connected to the rogue domain controller would still fail, because the controller does not have the machine password. This happens before verifying that the machine is also registered on the controller.Īt this point the attacker will have the ability to create a new password on the laptop, which will replace the original one in the local credentials cache. When authentication is attempted with the attacker's password on the laptop, the domain controller will inform Windows that the password has expired and the user will automatically be prompted to change it. He then creates the same user account on the controller as on the laptop and creates a password for it with a creation date far in the past. However, Haken figured out a way to do it - and it only takes a few seconds if automated.įirst, the attacker sets up a mock domain controller with the same name as the one the laptop is supposed to connect to. This additional check doesn't happen when the controller cannot be reached, because the protocol developers assumed that the attacker can't change the user password stored in the local cache.

Step#3 Copy the below code and paste it in that Note Pad file by typing your password in “CHANGE_YOUR_PASSWORD”.In order to prevent an attacker from connecting a stolen, lost or unattended laptop to a different network and creating a spoofed domain controller that accepts another password to unlock it, the authentication protocol also verifies that the machine itself is registered on the domain controller using a separate machine password. Remember to create that notepad file outside that folder. Step#2 Now open ‘Note Pad’ or any other ‘Text Editor’. Step#1 Create a Folder name ‘PRIVATE’ inside of folder you want to save your content.
