Denial of service using NTP servers to amplify attacks
It appears someone is using an attack vector like this to DDOS CloudFlare. I can not stress enough I have no involvement or participation in any such actions. This script is provided as is and its up to the end user to make mature and legal decisions about its usage.
If you need assistance mitigating this threat please contact me at my email listed on my github profile.
