The Domain Name System (DNS), if not properly secured, may be susceptible to abuse by malicious actors. Cybercriminals recognize the value of DNS availability and look for ways to compromise DNS uptime and the DNS servers that support it. As such, DNS becomes an important point of security enforcement and a potential point in the Cyber Kill Chain®1 for many cyber-attacks.
This blog discusses one such threat, DNS reflection and amplification attacks.

Launching a DDoS attack is much more accessible to attackers thanks to the rise of cloud computing, cheap hosting, readily available bandwidth and open-source attack tools. From low-skilled teenagers aiming to cheat while playing online games to cybercriminals looking to supplement their income by renting out their botnets for opportunistic attacks, the DDoS-for-hire market is booming.

User Datagram Protocol (UDP) flood attacks continue to dominate in Q3 2016, making up 49 percent of the total attacks in the quarter. The most common UDP flood attacks mitigated were Domain Name System (DNS) reflection attacks, followed by Network Time Protocol (NTP) reflection attacks.
The highest intensity flood attack in Q3 2016 was a TCP SYN flood that peaked at approximately 60 Gigabits per second (Gbps) and 150 Million packets per second (Mpps). This flood attack is one of the highest packets per second attacks ever observed by Verisign, surpassing the previous flood of 125 Mpps mitigated by Verisign in Q4 2015.
The largest attack in Q3 2016 utilized the Generic Routing Encapsulation (GRE) protocol (IP protocol 47) and peaked at 250+ Gbps and 50+ Mpps. This is the first time Verisign observed this type of attack against our customer base.
