Retrieving the NetBIOS name and MAC address of a host

NetBIOS name resolution is enabled in most Windows clients today. Even a debugging utility called nbtstat is shipped with Windows to diagnose name resolution problems with NetBIOS over TCP/IP. We can use NetBIOS to obtain information such as the computer name, user, and MAC address with one single request.

This recipe shows how to retrieve the NetBIOS information and MAC address of a Windows host with Nmap.

How to do it...

Open your terminal and enter the following Nmap command:

$ nmap -sU -p137 --script nbstat <target>

The NSE nbstat script will return the NetBIOS name, NetBIOS user, and MAC address of the system:

PORT  STATE SERVICE
137/udp open    microsoft-ds
MAC Address: 9C:2A:70:10:84:BF (Hon Hai Precision Ind.) Host script results:
|_nbstat: NetBIOS name: ALIEN, NetBIOS user: <unknown>, NetBIOS MAC: 9C:2A:70:10:84:BF (Hon Hai Precision Ind.)
