Obtaining information from MS SQL servers with NTLM enabled

MS SQL servers with NTLM authentication disclose NetBIOS, DNS, and OS build version information. This is excellent information to fingerprint a system accurately without authentication.

This recipe shows how to use Nmap to extract information from MS SQL servers with NTLM authentication enabled.

How to do it...

1433/tcp  open ms-sql-s
| ms-sql-ntlm-info:
|     Target_Name: TESTSQL
|     NetBIOS_Domain_Name: TESTSQL
|     NetBIOS_Computer_Name: DB-TEST
|     DNS_Domain_Name: 0xdeadbeefcafe.com
|     DNS_Computer_Name...
