The use of reflection-based distributed denial-of-service (DDoS) attacks continues to be on the rise, according to one recent study.
Arbor Network's “ATLAS Q3 2014 DDoS Attack Trends,” which combines traffic data from more than 290 service providers, found that reflection-based attacks dominated the third quarter findings, with SSDP reflection attacks accounting for 42 percent of “all events tracked over 10Gb/sec.”
Although NTP reflection attacks reduced in frequency compared to Arbor's Q1 and Q2 findings, they still accounted for more than half of all volumetric attacks greater than 100 Gbps.
The size of events also continues to trend upward, with 16.5 percent of attacks coming in at more than 1Gbps, an increase from 15.3 percent in Q2 findings. Additionally, a majority of attacks – 91.2 percent – lasting less than one hour has increased.
