DDOS Attacks Using NTP
This is new:
The NTP method first began to appear late last year. To bring down a server such as one running “League of Legends,” the attackers trick NTP servers into thinking they’ve been queried by the “League of Legends” server.
The NTP servers, thinking they’re responding to a legitimate query, message the “League of Legends” server, overloading it with as many as 100 gigabits per second (Gbps). That’s large even for a DDoS attack.
In this way, one small request to an NTP server can generate an enormous response capable of taking down even high-capacity websites.
