The trend of significant growth in DDoS attack size continues. In 2016, Arbor’s ATLAS system reported 558 attacks over 100 Gbps, as opposed to 223 in 2015.
Customers remain the number one target for DDoS attacks, with over two-thirds of attacks targeting them.
The largest attack reported this year was 800 Gbps, a 60 percent increase over last year. Other respondents reported attacks of 600 Gbps, 550 Gbps and 500 Gbps.
The proportion of respondents seeing DDoS attacks targeting cloud-based services has grown from 19 percent two years ago, to 29 percent last year and now 33 percent this year — a clear trend.
Infrastructure continues to be the most popular attack target reported by EGE respondents.
Nearly 60 percent estimate their downtime costs above $500/minute, with some indicating much greater expense.
Attack frequency is on the rise, with 45 percent experiencing more than 10 attacks per month — a 38 percent year-over-year increase.
