Until this is fixed, I will recommend using TPM + Pin or Password!!!. If an attacker grab that key, they should be able to decrypt the drive, get access to the VPN client config, and maybe get access to the internal network. The flaw is BitLocker does not utilize any encrypted communication features of the TPM 2.0 standard, which means any data coming out of the TPM is coming out in plaintext, including the decryption key for Windows. Summary: TPM is very secure and an attack on it is near impossible.

The SSD was full disk encrypted (FDE) using Microsoft’s BitLocker, secured via Trusted Platform Module (TPM).LAN turtle and other Responder attacks via USB ethernet adapters returned nothing usable.Kon-boot auth bypass did not work because of full disk encryption.

Secureboot was fully enabled and prevented any non-signed operating systems.

The BIOS boot order was locked to prevent booting from USB or CD.

All BIOS settings were locked with a password.

Pcileech/DMA attacks were blocked because Intel’s VT-d BIOS setting was enabled.

Once the got hold of the device, they headed straight to work and performed some reconnaissance of the laptop (BIOS settings, normal boot operation, hardware details, etc) and noted a lot of best practices were being followed, negating many common attacks. No prior information about the laptop, test credentials, configuration details, etc were given.

They were handed a Levovo Laptop preconfigured with the standard security stack for this organization. This is a recent research by security specialists of the Dolos Group to determine if an attacker can access the organisation network from a stolen device and also perform lateral network movement.
