This module exploits a denial of service vulnerability within the NTP (network time protocol) demon. By sending a single packet to a vulnerable ntpd server (Victim A), spoofed from the IP address of another vulnerable ntpd server (Victim B), both victims will enter an infinite response loop. Note, unless you control the spoofed source host or the real remote host(s), you will not be able to halt the DoS condition once begun!
To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
