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.

Usage:
Please consult ntpdos.py -h

ntpdos's Issues

Attack not having any impact

I added a script with all ntp servers that respond to monlist get requests but it doesn't seem to be doing any damage to my target. I tested it on my server and didn't actually see the ntp respond requests go through. Besides that Scapy only supports Layer 2 and 3 network transportation and not amplification on layer 4 with a respond from layer 7.

hi

Global name 'IP' is not defined

I execute the script on my localhost but it just says this

Sending...
Exception in thread Thread-5:

packet = IP(dst=ntpserver,src=target)/UDP(sport=random.randint(2000,65535),dport=123)/Raw(load=data) #BUILD IT
NameError: global name 'IP' is not defined
