We unveiled the official Metasploit song at the Rapid7 party this year at RSA. Metasploit is one of, if not the, most widely used tools in the hacker community. I personally have been using msf since it was coded in Perl (hint: it was overhauled in Ruby years ago).
The song is called Mastering Success and Failure (msf) and is free for download in multiple formats:
We would like to thank Rapid7, the Metasploit team, and everyone at the parties in San Francisco for making this such a fun experience 😀
