The intertubes have been humming lately around a certain NTP feature to gather lists of NTP servers’ clients and it naturally grabbed our attention. The humming was started by HD Moore recently where he revealed that it is possible to query NTP servers to get lists of addresses and using the information for fun and profit. He also mentioned that he will be releasing a paper describing all this and how he can create a sizable DDOS using NTP, without giving too much detail about it.
