Verisign Distributed Denial of Service (DDoS Attack) Trends Report
Verisign just released its Q2 2018 DDoS Trends Report, which represents a unique view into the attack trends unfolding online, through observations and insights derived from distributed denial of service (DDoS) attack mitigations enacted on behalf of customers of Verisign DDoS Protection Services.
Verisign observed that 52 percent of DDoS attacks that were mitigated in Q2 2018 employed multiple attack types. There was a 35 percent increase in the number of attacks, with a 49 percent decrease in the average of attack peak sizes, when compared to Q1 2018; however, the average of attack peak sizes has increased by 111 percent, year over year.
The largest volumetric DDoS attack observed by Verisign in Q2 2018 was a User Datagram Protocol (UDP) fragment flood that peaked at approximately 42 Gigabits per second (Gbps) and 3.5 Million packets per second (Mpps) and lasted approximately three hours. The highest intensity DDoS attack observed by Verisign in Q2 2018 was a multi-vector attack that peaked at approximately 38 Gbps and 4.7 Mpps, and lasted for approximately two hours.
