This Metasploit module sends these Crypto-NAK packets in order to establish an association between the target ntpd instance and the attacking client. The end goal is to cause ntpd to declare the legitimate peers "false tickers" and choose the attacking clients as the preferred peers, allowing these peers to control time.
