Users also have the option to create a USB bootable device.Īs it stands, only one device – the ASUS Q170M-C – is still vulnerable to the attack, Han said. Researcher Seunghun Han detailed his research during Black Hat Asia's virtual event Open source toolboxīitLeaker can be downloaded from the GitHub repository. “Additionally, we present detailed information on BitLocker’s VMK protection process related to the TPM and countermeasures.” “By exploiting the vulnerability, we extracted the VMK from TPMs and decrypted a BitLocker-locked partition with our custom tool, BitLeaker.

“PCRs are core parts of the sealing and unsealing functions to protect the VMK of BitLocker. Read more of the latest Microsoft security news “The sleep mode vulnerability can subvert not only the fTPM but also the dTPM with system sleep mode, and it can forge Platform Configuration Registers (PCRs),” Han explained. Your recovery key is the recovery key with a Device Name that matches the Recovery key ID on the recovery prompt. Click Manage, and then select Get BitLocker recovery keys to get the key. The bug – CVE-2020-0526 – was assigned a ‘medium’ risk level, as is was found that the security bug could also lead to privilege escalation. Click All Devices, locate the device name that matches the computer with the encryption issue, and then click Show details.

In his presentation at Black Hat Asia today, Han introduced an update to BitLeaker, unveiling a new vulnerability related to the fTPM, specifically in the Intel Platform Trust Technology (PTT), that can also be exploited. Han detailed a proof-of-concept in a video, in which he uses a USB bootloader. It was this vulnerability that allowed Han to access encrypted files by using the BitLeaker tool.

Two types of TPM – hardware-based discrete TPM (dTPM) and firmware-based TPM (fTPM) – are used to protect BitLocker’s Volume Master Key (VMK), the key that decrypts partitioned files.īack in 2018, Han and a team of researchers first discovered CVE-2018-6622, a local vulnerability in the dTPM 2.0.Īn advisory explains: “An abnormal case is not handled properly by this firmware while S3 sleep and can clear TPM 2.0.

Han explained how the tool BitLeaker, built for Windows 10, can leverage a vulnerability in the ACPI S3 sleeping state to bypass full disk encryption. It is compatible with Trusted Platform Modules (TPMs) and encrypts data stored on disk to prevent unauthorized access in cases of device theft or remote attacks. Microsoft’s data security technology exploited by BitLeaker toolĪ vulnerability in BitLocker’s “tamper-resistant” security technology can be exploited to break the full disk encryption technology that comes bundled with Windows devices.Īt the virtual Black Hat Asia security conference today, researcher Seunghun Han introduced a tool that can be used to subvert BitLocker security protections.īitLocker is Microsoft’s implementation of full disk encryption.
