By default, domain joined Windows workstations allow access to the network selection UI from the lock screen.

An attacker with physical access to a locked device with WiFi capabilities (such as a laptop or a workstation) can abuse this functionality to force the laptop to authenticate against a rogue access point and capture a MSCHAPv2 challenge response hash for the domain computer account.

This challenge response hash can then be submitted to crack.sh to recover the NTLM hash of the computer account in less than 24 hours.

Once recovered, this NTLM hash combined with the domain SID can be used to forge Kerberos silver tickets to impersonate a privileged user and compromise the host. An example of this is to create a silver ticket for the CIFS service of the laptop in order to authenticate over SMB as the SYSTEM user and gain unrestricted access to the hard disk.

As the attack can be performed from a locked device, it can be utilised to bypass BitLocker full disk encryption and gain access to the devices…
