By 2007, the Metasploit Framework had been completely rewritten in Ruby. The Metasploit Project is a computer security project that provides information about security vulnerabilities and aids in penetration testing and IDS signature development. Its best-known sub-project is the open source Metasploit Framework, a tool for developing and executing exploit code against a remote target machine. Other important sub-projects include the Opcode Database, shellcode archive and related research. http://jruby.org/ http://jruby.org/ An implementation of the Ruby programming language atop the Java Virtual Machine (JVM).
