Attacks Decrease by 23 Precent in 1st Quarter While Peak Attack Sizes Increase: DDoS Trends Report

Verisign DDoS Trends Report – Volume 4, Issue 1, 1st Quarter 2017 – Click to DownloadIn Q1 2017, Verisign saw a 23 percent decrease in the number of attacks; however, the average peak attack size increased 26 percent compared to the previous quarter. Overall, average peak attack sizes have been noticeably larger since Q1 2016, with peak sizes over 10 Gigabits per second (Gbps).

The largest volumetric and highest intensity DDoS attack observed by Verisign in Q1 2017 was a multi-vector attack that peaked over 120 Gbps and around 90 Million packets per second (Mpps). This attack sent a flood of traffic to the targeted network in excess of 60 Gbps for more than 15 hours. The attack was notable because the attackers were persistent, sending attack traffic on a daily basis for over two weeks. The attack consisted primarily of TCP SYN and TCP RST floods of varying packet sizes and employed one of the signatures associated with the Mirai IoT botnet. The event also included UDP floods and IP fragments which increased the volume of the attack.

Key DDoS Attack Trends and Observations

  • Fifty-seven percent of the DDoS attacks mitigated by Verisign in Q1 2017 employed multiple attack types.
  • Forty-six percent of DDoS attacks were UDP Floods.
  • TCP-based attacks were the second most common attack vector, making up 33 percent of attack types in the quarter.
