The hard drives of the device are not encrypted using a full volume encryption feature such as BitLocker. This allows an attacker with physical access to the device to use an alternative operating system to interact with the hard drives, completely circumventing the Windows login. The attacker can read from and write to all files on the hard drives.

The VNC application stores its passwords encrypted within the registry but uses DES for encryption. As DES is broken, the original passwords can be recovered.

The VNC authentication mechanism bases on a challenge-response system where both server and client use the same password for encryption. The challenge is sent from the server to the client, is encrypted by the client and sent back. The server does the same encryption locally and if the responses match it is prooven that the client knows the correct password. Since all VNC communication is unencrypted, an attacker can obtain the challenge and response and try to derive the password from this information.

All communication between the VNC server and client(s) is unencrypted. This allows an attacker to intercept the traffic and obtain sensitive data.
