Dumping password hashes of MS SQL servers

After gaining access to an MS SQL server, we can dump all the password hashes of the server to compromise other accounts. Nmap can help us retrieve these hashes in a format usable by popular cracking tools such as John the Ripper.

This recipe shows how to dump password hashes of an MS SQL server with Nmap.

$ nmap -p1433 --script ms-sql-empty-password,ms-sql-dump-hashes

The password hashes will be included in the script output section:
