Description

This module identifies NTP servers which permit mode 6 REQ_NONCE requests that
can be used to conduct DRDoS attacks. In some configurations, NTP servers will
respond to REQ_NONCE requests with a response larger than the request,
allowing remote attackers to cause a distributed, reflected
denial of service (aka, "DRDoS" or traffic amplification) via spoofed
requests.
