Metasploit was developed by HD Moore as an open source project in 2003. Originally written in Perl, Metasploit was completely rewritten in Ruby in 2007. In 2009, it was purchased by Rapid7, an IT security company that also produces the vulnerability scanner Nexpose.
Metasploit is now in version 4.9.3, which is included in our Kali Linux. It’s also built into BackTrack. For those of you using some other version ofLinux or Unix (including Mac OS), you can download Metasploit fromRapid7’s website.For those of you using Windows, you can also grab it from Rapid7, but I do not recommend running Metasploit in Windows. Although you can download and install it, some of the capabilities of this hacking framework do not translate over to the Windows operating system, and many of my hacks here on Null Byte will not work on the Windows platform.
