MetasploitAn open source attack framework first developed by H. D. Moore in 2003. Metasploit is used for hacking into systems for testing purposes. Metasploit provides useful information to people who perform penetration testing, IDS signature development, and exploit research. With the latest Metasploit 3.0 release, the project has moved to an all Ruby programming base.
