The third quarter of 2016 was one like no other in the history of the internet.

The period was punctuated by an unparalleled set of Distributed Denial of Service (DDoS) attacks, to which internet content delivery network and service provider Akamai, had a front row seat.

Akamai released its third quarter 2016 State of the Internet Security report on Nov. 15, providing insight into the scale of the attacks it observed during the quarter.

Among those attacks was a massive 623 Gbps attack against security blogger Brian Krebs, whose site was being protected by Akamai’s technology. Krebs’ site wasn’t the only one being hit by high-bandwidth DDoS attacks in the third quarter, Akamai reported a 138 percent year-over-year increase in the number of attacks greater than 100 Gbps. Overall, there was a 71 percent increase in the total number of DDoS attack reported during the third quarter of 2016.

Among the many techniques used by attackers with increasing success is DNS reflection, which helps to amplify the total attack bandwidth directed at online targets.

This slide show looks at some of the key findings in the third quarter 2016 Akamai State of the Internet Security report.
