Consider a Windows computer with NetBIOS file sharing enabled on it. How vulnerable is it?
First, the computer must have file sharing enabled and bound to TCP/IP. Then, you have to configure shares (drives and files for sharing) on your system. If you haven't done that, then there is no potential risk. For an in-depth report on the security risks involved with a Windows network, see "CIFS: Common Insecurities Fail Scrutiny."
If you have file sharing turned on and shares are configured, then you can take the next step to see if your system is vulnerable.
