--sploitego Sploitego's bruteforce method

• Brute forces both version 1 and version 2c SNMP community strings
• Enumerates information for CISCO devices or if specified for Linux and Windows operating systems.
• Identifies RW community strings
• Tries to download the router config (metasploit module).
• If the CISCO config file is downloaded, shows the plaintext passwords (metasploit module) and tries to crack hashed passords with John the Ripper
