Abusing Network Time Protocol (NTP) to perform massive Reflection DDoS attack
Jan 03, 2014
In 2013, we have seen a significant increase in the use of a specific distributed denial of service (DDoS) methodology known as Distributed Reflection Denial of Service attacks (DrDoS). Open and misconfigured DNS (Domain Name System) can be used by anyone to resolve domain names to IP addresses are increasingly abused to launch powerful DDoS attacks. But not only the DNS servers, Security Researchers at Symantec have spotted Network Time Protocol (NTP) reflection DDoS attacks being launched by cyber criminals during the Christmas Holidays. ' Network Time Protocol (NTP) ' is a distributed network clock time synchronization protocol that is used to synchronize computer clock times in a network of computers and runs over port 123 UDP. NTP is one of those set-it-and-forget-it protocols that is configured once and most network administrators don't worry about it after that. Unfortunately, that means it is also not a service that is upgraded often, leaving it vulnerable to th...
